General

RMR-36/40.5kV is completely insulated SF6 Gas insulated Switchgear.
This product is in conformity with the standards the GB/IEC standard and the design of a high safety combined switch cabinets.

The system of RMR-36/40.5kV of combined switch cabinets can be divided into three kinds of unit cabinet:

++++ 3 position cable connection unit (Cable switch unit), additional live shows and configuration of surge arresters and grounding fault component. Code C

++++3 position switch and fuse tripping system and earthing switch interlock system fuse combined electrical unit (Fuse combination unit), additional live shows and configuration of surge arresters and grounding fault component. Code F

++++3 position switch and vacuum circuit breaker combined appliances unit (Vacuum circuit breaker unit), additional current transformer, live shows and configuration of surge arresters and grounding fault component. Code V

The combination of the current transformer and the microcomputer protection to constitute the basic circuit protection function.

Microcomputer protection using passive protection and CT electric no need of additional PT
