Manufacturing
Key Components
Core
The core material is made of high-quality cold-rolled grain-oriented silicon steel sheet
(amorphous alloy core uses amorphous alloy material). The core adopts 45º fully oblique
seam step-by-step lamination technology, the core-through screw pull plate structure, and
the automatic stacking robot technology of silicon steel sheets to ensure the size alignment of
the entire stack of silicon steel sheets and the lapping accuracy between sheets. High-quality
materials and complete technology can effectively reduce the no-load loss and noise level. The
outer surface of the core is coated with F-grade or H-grade black elastic two-component resin
paint, which can effectively prevent dust and rust.
HV winding
The HV winding adopts a cylindrical structure wound
continuously with insulated copper wire and double-layer
insulation. Under the vacuum state, the high-grade imported
epoxy resin is used for overall high-temperature curing and
molding. The mechanical strength after curing is very high, and
the ultimate surface tensile stress can reach the strength of
steel. The surface and air passage are very smooth, and it is
difficult for dust to adhere to the coil surface.
LV winding
The LV winding is made of a whole piece of round-edged
copper foil. The interlayer is insulated with thermosetting
epoxy prepreg cloth, which is cured at high temperature in
a curing furnace. There is no helix angle at the end of the
low-voltage foil winding coil, and the ampere-turn can be
automatically balanced in the axial direction according to the
distribution of the high-voltage coil, so that the short-circuit
electromotive force can be reduced to a minimum in the case
of a serious external short-circuit fault.
7
LV foil winding machine
The LV coil can be wound with electromagnetic wire, and Eaton
also produces LV transformers with foil coils, which have the
advantages of uniform electric field distribution and strong
short-circuit resistance. LV foil coils are tightly wound with highpurity round-edged foil tape and insulation pre-impregnated
with epoxy resin. The LV foil winding machine has the functions
of constant tension, deburring, and automatic deviation
correction.
Resin vacuum casting system
After the finished coil is pre-dried, it is transferred to the pouring
cabin of the epoxy resin vacuum casting equipment for vacuum
drying to remove moisture and gas in the insulation. At the same
time, materials such as epoxy resin and hardener are continuously
degassed in an independent material preparation tank. After the
processing process, the computer injects various chemical materials
into the mold according to the set ratio through the precision
metering system. After pouring, it is cured at high temperature in an
oven, and finally made into a strong solid coil.
Manufacturing
Production Process
Core automatic stacking equipment
The core is one of the key components of the transformer.
Eaton adopts first-class equipment, advanced technology, and
high-quality materials to ensure the quality of the core, which
greatly reduces the no-load loss and noise of transformers.
HV automatic winding machine
The HV coil automatic winding machine is controlled by a computer
program and has the functions of constant tension and automatic
winding. The HV coil is made of copper magnet wire, wound
together with insulating materials such as glass fiber, and adopts
a segmented cylindrical structure with low interlayer voltage and
strong overvoltage resistance. Larger capacity coils are equipped
with heat dissipation air passages, which have good heat dissipation
performance.

Optional Accessories
Optional Accessories
Cooling Fan
The transformer can be cooled by two modes: air natural cooling
(AN) and air forced cooling (AF). Forced-air AF output of the
transformer is up to 140% of the self-cooled rating, should be
used only for emergency non-recurring loads, and but is not
recommended for long-term running.
Steel-plate enclosure
The steel-plate enclosure is made of high-quality cold-rolled
steel plate, which is processed by CNC shearing machine,
CNC punching machine, and CNC plate bending machine. The
steel plate shell has the advantages of beautiful and exquisite
appearance, good ventilation performance, simple and quick
installation, and convenient transportation. The color of the steel
plate shell is RAL7032 computer gray or customized according to
user requirements.
Temperature Controller
The temperature is controlled by means of sensor provided
on each transformer. The sensor (PT100) is installed in the LV
winding. The digital controller shows the operating temperature
of each LV winding, sequentially. The temperature controller
performs the following functions of three-phase winding during
transformer running: automatically switch the cooling fans on at
100℃ and off at 80℃, it will send an over-temperature alarm at
130℃ , and will send emergency shutdown trip signal at 150℃
and sensor fault alarm.
Stainless steel enclosure
Stainless steel enclosure, the main material is stainless steel plate,
which is beautiful and anti-corrosion, and can be easily assembled
on site, with inspection doors on the front and back. The shell
protection device provides a safety barrier for the live parts, and
the protection level reaches IP20, IP23 and above. The IP20 casing
can prevent the entry of solid foreign objects with a diameter
greater than 12mm; the IP23 casing can also prevent the inflow of
water droplets within 60º from the vertical line.

干式变压器 Quality Control
Quality Control
Eaton quality control was carried out according
to ISO9001 quality management standard and
production standard, there are many quality
engineers working for IQC, PQC, FQC and OQC. All
transformers should be inspected and tested by
operator, auditor and inspector according to the
production standards and requirements before it
been transported to the next production process,
the failed product will be rejected. The product's
quality and reliability are ensured by our strict
management procedure, serious working attitude
and advanced testing equipments.
