Product Overview
The SRM6-12 gas-insulated metal-enclosed switchgear is a three-phase AC 50Hz, fully insulated and fully sealed metal-enclosed switchgear using SF6 gas.
It adopts a modular design, using vacuum circuit breakers, load switches, load switch-fuse combination devices, isolating switches, and other main switches as functional units, placed in a sealed gas chamber to form various gas-filled compartment units. The busbar can be expanded in the left and right directions through busbar connectors, and the incoming and outgoing lines use plug-in cables. It is not affected by the environment, has high safety, is maintenance-free, and has strong reliability.
Widely used in industrial and civil ring network distribution systems and power supply terminals, especially suitable for small secondary substations, industrial and mining enterprises' switchgear, urban residential communities, airports, railways, and other places.
