1 Summary

1.1 Scope of application

The RM AirSeT Environmental protection gas insulated ring main unit is fully insulated and sealed according to GB and lEC standards, and does not require replenishment during the product life cycle.
Suitable for harsh environments.

Compact design, 3-position load switch: closing opening isolation earthing, multiple solutions to meet more stringent requirements.

1.2 Installation conditions

Environmental temperature: Lower or equal to 40 C; Above or equal to -25 C (For low-temperature use, please consult the manufacturer)

Altitude: ≤ 1000m (above 1000m, please consult the manufacturer)

Humidity: Less than or equal to 95% (24 hours); Less than or equal to 90% (1 month)

1.3 Product main features

Robust design

The structure of insulated metal enclosed switchgear reduces the difficulty of maintenance operations. With an undisputed leading position in the field of medium voltage secondary switchgear, the company has conducted a comprehensive experience feedback evaluation to improve quality and provide outstanding benefits:

• 30 years of research and development experience

• No need to refill the gas

• Long mechanical life

• New operating mechanism

• Composite materials require no lubrication and are already used extensively in the aviation and automotive industries

Totipotent architecture

The RM AirSeT Environmental protection gas insulated ring main unit (GIS) mainly used for medium voltage secondary distribution.

Can achieve 1-6 function common box, usually used in ring network or radiation distribution network connection, isolation or earthing.

Thanks to the new vacuum circuit breaker, RM AirSeT enables new applications such as closed-loop power distribution solutions:

• Automatic transfer switch (ATS)

• Closed-loop distribution network

• Automatic reclosing

Based on the successful concept of "free combination" launched by the company on the RM6 series a few years ago, RM AirSeT provides a more flexible combination solution:

• Easy to expand: The switchgear can be freely combined

• Up to 6 functions can be achieved in a shared box

• Modular design

Digitization

RM AirSeT has all the functions required for a smart grid

Plug and play: can be upgraded electrically on-site.

Optimized asset management: based on environmental monitoring sensor technology (temperature,

humidity, flood, intrusion...)

Openness: compatible with both company and other brand DTU

Progressiveness: provide highly integrated intelligent ring network cabinet, including many functions such as distributed DTU Easergy T300

2 Main technical parameters

Restrictions on free combination

① For special customization, please consult the manufacturer.

②PT (Voltage transformer cabinet) and M (metering cabinet) are independent: PT cabinet and M cabinet are specific functional units. Can only be modular and cannot be containerized. Can only be connected through scalable RM AirSeT (PT).
