Product Overview
Eaton Cable Support Solutions 4
Strut Support Systems
B-Line series strut systems is engineered to provide structural support in
any environment. A wide variety of finishes, configurations, and fittings
meet any construction need. B-Line series strut systems works in
conjunction with B-Line series ladder tray as a preferred method of cable
support. Seismic solutions also available.
Marine Ship Ladder
B-Line series marine ship ladder is ideal for offshore and confined space
applications. A full line of galvanized and stainless steel sections and
radiused fittings are available along with key accessoies.
Perforated & Solid Bottom Cable Tray
B-Line series perforated and solid bottom cable tray provides a continuous
bottom surface, allowing for constant cable support with no cable sag.
Radiused cable fittings allow the cables to adhere to cable manufacturer's
bend recommendations. An inside or outside flange on top of the tray
provides added strength. Additional flange options available.
Steel Cable Ladder
B-Line series cable ladders utilize an engineered I-Beam siderail profile, the
strongest available siderail shape. The I-Beam provides more strength using
less material than C-shaped siderails. The added strength means that the
ladders are lighter and easier to install. Rungs for all cable
ladders support a 90kg concentrated load beyond the
cataloged cable load.
Aluminum Cable Ladder
Ideal for onshore and offshore applications, B-Line series aluminum cable
ladders are manufactured from marine-grade aluminum. Similar to the steel
cable ladders, aluminum cable ladders include the I-Beam siderail for added
strength. Options are available to minimize the number of
supports required for the ladder, including mid-span splice
plates and extra-long lengths.
Cable Cleats
B-Line series cable cleats are designed to support and retain your cables
within your cable tray system in everyday conditions. More importantly,
they help prevent damage in short circuit conditions. Cable cleats are one
of the first lines of defense to help protect your personnel, your cables, and
your cable ladder and tray systems.

Lower total install cost solution through
reduction of structural steel supports
Eaton provides solutions that de-risk by design and drive value to our end customers. With Eaton’s
B-Line series cable ladder, Eaton provides support recommendations that meet and exceed NEMA
VE-2 requirements. These methods have been applied across the globe on multiple applications and
projects, and have saved customers millions of dollars on structural steel.
This brochure provides an overview of Eaton’s recommendations for structural steel supports when utilizing Eaton’s B-Line
series cable ladder, !ttings and splice plates. For additional information, and online resources and tools, visit Eaton.com/SSS.
Cable ladder best practice
To maximize cost savings on any cable ladder project, it
is essential that:
tElectrical and structural engineers and contractors
communicate effectively
tSupport plans and layouts are discussed early on within
the project life cycle (FEED - Front End Engineering
Design) to ensure proper support placement, minimize
construction complexity, and reduce budget spend
Support location best practice
1/4 Span - The method of placing supports at 1/4 span
away from a splice plate location on continuous runs.
tRecommended installation method by NEMA VE 2 and
Eaton’s B-Line series
tUp to 50% de\"ection reduction over simple beam or
mid span installations
tEliminates hold down clamp and splice hardware
interference issues during thermal expansion and
contraction
tSee Fig. 1A and Fig. 1B for visual stress comparison
Mid-Span - The method of placing supports at 1/2 span
away from a splice plate location on continuous runs.
tExcessive system de\"ection and stress experienced
compared to 1/4 span support methodology
tRequires additional supports to account for proper
thermal expansion and contraction
tSplice plate performance becomes more in\"uential on
de\"ection
tSee Fig. 2A and Fig. 2B for visual stress comparison
Simple Beam (Over Support) - The method of placing
supports directly under the splice plate locations on
continuous runs.
tMaximum system de\"ection and stress experienced
tLeads to possible installation issues not allowing for
proper thermal expansion and contraction
tSee Fig. 3A and Fig. 3B for visual stress comparison

Metric Cable Ladder Technical Guide
The technical data contained within this guide is intended to provide the engineer with adequate information
to design and specify an efficient and robust cable ladder system. Eaton recommends that the engineer
considers the following subjects when designing the cable ladder system which are detailed within the
corresponding sections of this guide:
1. Side Rail and Rung Design
2. Materials
3. Finish
4. Corrosion
5. Load Performance Type Tests
6. Environmental Loads
7. Impact
8. Electrical Continuity
9. Free Base Area
10. Thermal Contraction and Expansion
11. Support and Installation Recommendations
12. Cable Restraint
1. Side Rail and Rung Design
B-Line series cable ladder side rail uses a high performance extruded (aluminum) and rolled (steel)
I-Beam profile. The more complex the structural profile, the higher the strength yielded by the profile.
The I-Beam profile provides greater performance than standard C-section and complex C-section
profiles commonly used in cable ladder designs. Due to the higher performance provided by the
I-Beam it allows for a reduced material gauge thickness, reducing product weight.
The slotted steel side rail is designed to provide equally spaced slots along the entire length. These
allow for the installer to field cut and modify the standard length and connect new lengths and/or
fittings with a standard splice plate without the need for on-site drilling. The slots also allow the
designer and installer to use the slots for the attachment of additional accessories and equipment,
again without the need to drill the cable ladder. In addition, the slots result in a lighter weight ladder
with increased ventilation.

Steel Grade S275:
B-Line series cable ladder is manufactured from continuously roll formed Grade S275 structural steel or
equivalent. Use of a structural grade steel guarantees the material to meet the minimum structural and
chemical properties specified in the BS EN 10025-2 : 2004 standard.
Aluminum:
Aluminum cable ladders are fabricated from structural grade “copper free” (marine grade) aluminum
extrusions. Aluminum’s excellent corrosion resistance is due to its ability to form an aluminum oxide film
that when scratched or cut reforms the original protective film. Aluminum has excellent resistance to
“weathering” in most outdoor applications. Aluminum cable ladder has excellent corrosion resistance in
many chemical environments and has been used for over forty years in coastal petro-chemical plants and
offshore FPSO facilities located globally. Typically, aluminum cable ladders can perform indefinitely, with
little or no degradation over time, making it ideal for many chemical and marine environments.

Stainless Steel Grade 1.4404 (AISI 316L):
B-Line series cable ladder is manufactured from continuously roll formed Grade 1.4404 (AISI 316L) stainless
steel. Grade 1.4404 is a non-magnetic stainless steel and part of the “austenitic” group of stainless steels.
It is designed to withstand corrosive atmospheres, low and high ambient and operating temperatures.
Grade 1.4404 is a superior grade of stainless steel due to it containing molybdenum. This enhances its
resistance to corrosion and makes it appropriate for use in marine salt laden saliferous environments. The
importance of using Grade 1.4404 (AISI 316L) relates to the corrosion resistance of the steel after welding.
Stainless steel resists corrosion because it forms an impervious passive oxide layer on its surface which
forms when oxygen is present. When stainless steel is welded it may lead to a chromium carbide to
precipitate at the grain boundaries, depleting the chromium within the austenite and preventing the passive
oxide layer from forming. Due to the grain boundaries being small and highly anodic, a rapid corrosion can
occur. This process can be prevented by using stainless steels with a carbon content of less than 0.03%.
Grade 1.4044 typically has less than 0.03% carbon content.
There are a number of important factors that can make the use of stainless steel imperative. These factors
can include long term maintenance costs, corrosion resistance, aesthetic appearance, and ambient
operating temperature. Grade 1.4404 stainless steel exhibits stable structural properties such as yield
strength and high creep strength at lowered and elevated ambient operating temperatures.
B-Line series cable ladder is welded using a stainless steel welding wire to ensure each weldment exhibits
the same corrosion resistance as the base metal. Localized staining in the weld area/heat effected zone
may occur when exposed to severe corrosive environments. The shielding gases and low carbon materials
used in our welding processes minimise carbon contamination during welding to reduce staining and stress
corrosion.

3. Finish
Zinc Coatings
Zinc protects steel in two ways. First it protects the steel
as a coating and second as a sacrificial anode to repair
bare areas such as cut edges, scratches, and gouges. The
corrosion protection of zinc is directly related to its
thickness and the environment. This means a .2 mil coating
will last twice as long as a .1 mil coating in the same
environment.
Zn
Fe
ZnFe
ZnO
Galvanizing also protects cut and drilled edges.
Hot Dip Galvanized After Fabrication
(Hot dip galvanized or batch hot dip galvanized)
Hot Dip Galvanized After Fabrication cable ladder products are fabricated from steel and then completely
immersed in a bath of molten zinc. A metallic bond occurs resulting in a zinc coating that completely
coats all surfaces, including edges and welds.
Another advantage of this method is coating thickness. Cable ladders hot dip galvanized after fabrication
to provide an average minimum zinc coating thickness in accordance with BS EN ISO 1461.
The zinc thickness is controlled by the amount of time each part is immersed in the molten zinc bath
as well as the speed at which it is removed. The term \"double dipping\" refers to parts too large to fit
into the galvanizing kettle and, therefore, must be dipped one end at a time. It does not refer to extra
coating thickness.
The layer of zinc which bonds to steel provides a dual protection against corrosion. It protects first as
an overall barrier coating. If this coating happens to be scratched or gouged, zinc's secondary defense
is called upon to protect the steel by galvanic action.
Hot dip galvanizing after fabrication is recommended for prolonged outdoor exposure and will protect
steel for many years in most outdoor environments and in many aggressive industrial environments .
4. Corrosion
IEC 61357 : 2006 section 6.5.2, Table 1 “classification for resistance against corrosion” defines the
classification class of various materials and finishes used in the manufacture and supply of cable
ladder systems against resistance to corrosion.
In accordance with this classification table, B-Line cable ladder can be supplied as to meet the
following classifications:
Steel HDG : Class 6
Stainless Steel 1.4404 : Class 9B
Passivated Stainless Steel 1.4404 : Class 9D
Stainless Steel
Several important conditions could make the use of stainless steel imperative. These include long
term maintenance costs, corrosion resistance, appearance and locations where product
contamination is undesirable. Stainless steel exhibits stable structural properties such as yield
strength and high creep strength at elevated temperatures.

5. Load Performance Type Tests
B-Line series aluminum and steel cable ladder has been performance load tested in full compliance with
the requirements of IEC 61537 : 2006 standard titled “Cable Management - Cable Tray Systems and
Cable Ladder Systems” and load and deflection results published within this catalog are based upon
these tests. Type load tests have been witnessed by DNV and BV independent third party inspectorates.
We recommend that the specifying engineer insists upon independent third party certificates confirming
compliance to the IEC standard and published load tables within the manufacturer's catalog.
Eaton has tested B-Line series cable ladder to the following type tests detailed within the IEC 61537
standard:
Type Test - II
6. Environmental Loads
Wind Loads
Wind loads need to be considered for all
outdoor cable ladder installations. The most
severe loading to be considered is impact
pressure normal to the cable ladder side
rails.

Technical Data
When covers are installed on outdoor cable
ladders, another factor to be considered is the
aerodynamic effect which can produce a lift
strong enough to separate a cover from a
ladder. Wind moving across a covered ladder
(see detail 2) creates a positive pressure inside
the ladder and a negative pressure above the
cover. This pressure difference can lift the cover
off the ladder.
Eaton recommends the use of high performance cover clamps when covered ladders are installed
in an area where strong winds occur.
Eaton’s engineering services can calculate direct
wind forces on B-Line series cable ladder systems,
the resultant forces at hold down clamp locations,
cover uplift forces, and FPSO modular transportation
effects.
Please reach out to a Eaton application engineer
for more information.

Ice Loads
Glaze ice is the most commonly seen form of ice build-up. It is the result of rain or drizzle freezing on
impact with an exposed object. Generally, only the top surface (or the cover) and the windward side of
a cable ladder system is significantly coated with ice. The maximum design load to be added due to ice
should be calculated as follows:
LI = ( W x TI ) x DI where; 1,000,000
LI= Ice Load (kg/m)
W= Cable Tray Width (mm)
TI= Maximum Ice Thickness (mm)
DI= Ice Density = 913 kg/m3
The maximum ice thickness will vary depending on location. A thickness of 12mm can be used as a
conservative standard.
Snow Loads
Snow is measured by density and thickness. The density of snow varies almost as much as its
thickness. The additional design load from snowfall should be determined using the building codes
which apply for each installation.
7. Impact
B-Line series cable ladder conforms to an Impact Test Value of 50J based on the IEC 61537:2006,
Section 10.9 at a temperature of -60°C.
8. Electrical Continuity
Electrical continuity testing of B-Line series cable ladder was conducted in accordance with
IEC 61357 : 2006, section 11.1.2 and results in an electrical impedance less than 50milli ohms across
the joint and 5 milli ohms per metre without a joint. No bonding jumper cables are required except for
expansion splice locations and mechanically discontinuous sections.
9. Free Base Area
In accordance with IEC 61537; 2006, section 6.8, Table 5 “Free Base Area Classification”, B-Line
series cable ladder has a classification of ‘Y’ on standard 300mm rung spacing and a calculated free
base area of 86%. B-Line series aluminum I-Beam style rung has a classification of “Z” on standard
300mm rung spacing and a calculated free base area of 90%.

It is important that thermal
contraction and expansion be
considered when installing cable
ladder systems. The length of the
straight cable tray runs and the
temperature differential govern the
number of expansion splice plates
required (see Table 2 below).
The cable ladder should be
anchored at the support nearest
to its midpoint between the
expansion splice plates and
secured by expansion guides
at all other support locations
(see Figure 1). The cable ladder
should be permitted longitudinal
movement in both directions from
that fixed point. When used,
covers should be overlapped at
expansion splices.
Accurate gap settings at the time
of installation are necessary for the
proper operation of the expansion
splice plates. The following
procedure should assist the
installer in determining the correct
gap: (see Figure 2)
Plot the highest expected
metal temperature on the
maximum temperature line.
Plot the lowest expected
metal temperature on the
minimum temperature line.
Draw a line between the

11. Support and Installation Recommendations
Deflection
Deflection in a cable ladder system is primarily an aesthetic consideration. When a cable ladder system is
installed in a prominent location, a maximum simple beam deflection of 1/100 of support span can be used
as a guideline to minimize visual deflection.
There are two typical beam configurations: simple beam and continuous beam.
An example of a simple beam is a single straight section of
cable ladder supported, but not fastened at either end. When the
ladder is loaded the cable ladder is allowed to flex. Simple beam
support is seldom used in field installations.
Continuous beam is the beam configuration most commonly used
in cable ladder installations. An example of this configuration is
where cable ladders are installed across several supports to form
a number of spans. The continuous beam possesses traits of both
simple and fixed beams. When equal loads are applied to all spans
simultaneously, the counter balancing effect of the loads on both
sides of a support restricts the movement of the cable ladder at
the support. The effect is similar to that of a fixed beam. The end
spans behave substantially like simple beams. When cable ladders
of identical design are compared, the continuous beam installation
will typically have approximately half the deflection of a simple
beam of the same span. The following factors should be
considered when addressing cable ladder deflection:
1. Deflection in a cable ladder system can be reduced by decreasing the support span, or by using a
taller or stronger cable ladder.
2. Economic consideration must be given when addressing cable deflection criteria. Eliminating deflection
can mean purchasing a stronger ladder at higher cost.
3. The location of splices in a continuous span will affect the deflection of the cable ladder system. The
splices should be located at points of minimum stress whenever practical. Eaton recommends
the following for splice installation:
Straight section lengths should be equal to or greater than the span length to ensure not more than
one splice between supports.
See the figures below for splicing configuration samples.

Future Expansion Requirements
One of the many features of cable ladder is the ease of adding cables to an existing system. Future
expansion should always be considered when selecting a cable ladder, and allowance should be made
for additional fill area and load capacity. A minimum of 50% expansion allowance is recommended.
Installation
Shorter cable ladder lengths are typically easier to maneuver on the job site during installation. Two
people may be needed to manipulate longer cable ladder sections, while shorter sections might be
handled by one person. Although longer cable ladder lengths are more difficult to maneuver, they
can reduce installation time due to the fact that there are fewer splice connections. This trade-off
should be evaluated for each set of job site restrictions.

12. Cables and Cable Restraint
Type of Cable
In general, small, highly flexible cables should be installed in cable ladders with close rung
spacing of 225mm or less. Larger, less flexible cables are typically installed in cable ladders
having 300mm rung spacing. Cable ladders having rung spacing greater than 300mm should be
used for very large, stiff cables to reduce cost and facilitate cable drop-outs.
Cable Exposure
Many cable jackets are manufactured to withstand the environment without additional protection,
favoring the use of the cable ladder. Cable jackets should be evaluated during project design for
suitability in the project application.
Cable Attachment
A major advantage of cable ladder is the freedom of entry and exit of the cables. Another
advantage of cable ladder is the ability to secure cables in the cable ladder. With standard rungs,
the cables may be attached with either cable ties or cable clamps. Cable attachment is particularly
important on vertical runs or when the ladder is installed on its side. Ladder rung spacing should
be chosen to provide adequate cable attachment points while allowing the cables to exit the
system.
Cable Flexibility
The proper bend radius for cable ladder fittings is usually determined by the bend radius and
stiffness of the cables to be installed. Typically, the cable manufacturer will recommend a minimum
bend allowance for each cable. The fitting radius should be equal to or larger than the minimum
bend radius of the largest cable which may ever be installed in the system. When several cables
are to be installed in the same cable ladder, a larger bend radius may be desirable to ease cable
installation.
Space Limitations
The overall dimensions for a cable ladder fitting will increase as the bend radius increases. Size
and cost make the smallest acceptable fitting radius most desirable. When large radius fittings are
required, the system layout must be designed to allow adequate space.

Cable Ladder Construction - Straight Section Side Rails
B-Line series cable ladder side rails have an engineered I-Beam shape to provide system
integrity. The I-Beam is the most efficient structural shape, providing strength without
increasing the weight of the side rail itself. This shape, in conjunction with the slots in the side
rails, offers the optimum design.
In addition, the I-Beam shape has a number of other advantages:
Profile Dimensions
Side Rails: Strength and Safe Working Load
Side rails provide the strength of the ladder system. The load ratings for the side rails in this catalog
are based on testing to IEC 61537, 2006 Edition, Test Type II. Values in the catalog load charts are
based upon allowable deflection and safe working loads calculated using a 1.7 factor of safety.
Material Thickness
1) Roll-formed steel increases the strength of the steel itself
2) Enlarged top flange adds stiffness to the system
3) Bend in side rail to lock in rung position and provide more
material for a solid weld
4) Bottom rail surface provides positive support for rungs
5) Slotted side rail design reduces installation time

Rung Profile Dimensions
Cable Ladder Construction - Rungs
Rungs are designed to maintain the system strength and provide a convenient place to affix
cables. All rungs have slots on the upper surface, sized for M10 hardware, to allow for the
attachment of banding or cleats.
Rungs
Standard rungs (C) have a profile as shown in the rung profiles below. The standard rung
orientation is all rung openings down (D) with options of all rung openings up (U), or
alternating rung openings up and down (A).
There are two profiles of rungs available as shown in the rung profiles dimensions below.
A standard rung version (C) and a strut rung version (B).
Rung Options
• Rung Spacing: Rungs can be spaced at intervals other than 300mm on straight
sections only. To order an alternate rung spacing, change the default “300” value for
the spacing following the material type or finish. Non-standard rung spacing is
not available on fittings.
Example: 125G200CA15ILL-0600-3000 is a ladder with 125mm height,
hot dip galvanized finish, 200mm rung spacing, SDL Series, 600mm width,
and a 3m length.
• Strut Rung: A strut-type profile can be ordered instead of the standard profile.
To order a strut-type rung, change the default “C” value for standard rung to a “B” for
strut-type rung.
Example: 125G300BA15ILL-0600-3000 is a ladder with 125mm height, hot
dip galvanized finish, 300mm rung spacing, strut type rung, SDL Series,
600mm width, and a 3m length.
• Rung Orientation: Rungs can be oriented with open side up or alternating, instead of
the standard down orientation. To order rungs with all up or alternating orientation,
change the default “D” value for down rungs to “U” for all rungs with open side up
or “A” for alternating up and down rungs.
Example: 125G300CU15ILL-0600-3000 is a ladder with 125mm height, hot
dip galvanized finish, 300mm rung spacing, standard rung, all rungs oriented with
open side up, SDL Series, 600mm width, and a 3m length.

Cable Ladder Construction - Fittings
B-Line series cable ladder fittings are designed to carry loads greater than the straight
sections. The C-shape of the fitting side rails is designed with the same height and width
for easy attachment to straight sections.
Fittings
All fittings have a straight tangent section at each end. The tangent allows the splice plate
to be flush against both the straight section and the fitting when they are connected,
increasing the contact surface area and the strength of the overall system.
Standard rung spacing for fittings is 300mm, and the standard rung orientation is down.
Different rung types and orientations are available (see “Cable Ladder Construction - Rungs”
reference page 40).
Fitting Options
• Radius: Alternate radiuses may be available on request. Please consult B-Line for

Steel Cable Ladder
All dimensions are in millimeters unless otherwise specified.
Steel Cable Ladder - Straight Section Covers
A full range of covers is available for straight sections and fittings.
Solid covers should be used when maximum enclosure of the cable is desired and no accumulation of heat is expected.
Ventilated covers allow heat to escape and minimize effects of wind pressure in outdoor applications.
Eaton recommends that covers be placed on vertical cable ladder runs to a height of 1.5m to 2.5m above the floor to isolate both cables and personnel.
Cover clamps are not included with the cover and must be ordered separately.
