PBSRM6-12 Gas Insulated Metal Enclosed Switchgear

Short Description:

Product Detail

Product Tags


PBSRM6-12 gas-insulated metal-enclosed switchgear is a three-phase AC 50Hz, SF6 gas fully-insulated and fully-sealed metal-enclosed switchgear.
Modular design is adopted, and main switches such as vacuum circuit breaker, load switch, load switch-fuse combination electrical appliance, and isolating switch are used as functional units, which are placed in a sealed air box to form each inflatable compartment unit. The busbar can be connected through the busbar connector. Extend arbitrarily in the left and right directions, and use plug-in cables for incoming lines. Not affected by the environment, high safety, maintenance-free, and strong reliability.
It is widely used in industrial and civil ring network power distribution systems and power supply terminals, especially in small secondary power distribution stations, industrial and mining enterprise opening and closing stations, urban residential quarters, airports, railways and other places.
