Made by advanced technology, our indoor medium voltage switchgear features stable performance, safety and reliability. The gas insulated switchgear comes in full range of specifications, and is mainly used as a monitor and protector by electric power plants, industrial and mining enterprises, secondary substation power distribution systems, and large-scale high-voltage motors.
The XGN15 series air insulated switchgear for secondary distribution system consists of cabinet and handcart. The cabinet is divided into several functional compartments by metal partitions:
1. busbar room
2. circuit breaker room
3. cable room
4. operating mechanism, interlocking mechanism, low voltage control room
As the user needs, the XGN15 type RMU can be equipped with SF6 load switches, circuit breakers, relays, CT, PT, arrestors, earthing switches, disconnectors and overcurrent, short circuit fault indicators. Circuit breakers and disconnectors can implement mechanical interlock, and can meet remote control requirements.
The main switch of the medium voltage switchgear can be of the following brands:
1. Tellhow-FLN36, FLN38 SF6 load switch, Tellhow-TZNH series vacuum circuit breaker.
2. ABB-SFG load switch, ABB-HD4 vacuum circuit breaker.
3. Schneider-SC6 load switch.
4. Imported ISM series permanent magnetic actuator vacuum circuit breaker.
