LY-12 Gas Insulated Switchgear Series

LY-12 Gas Insulated Switchgear Series

The LY-12 gas insulated switchgear series is a compact metal-sealed switchgear system designed for 10KV power distribution systems. It offers unique flexibility with its expandability, allowing for full and semi-modular combinations.

The stainless steel gas chamber of the LY-12 switchgear is filled with SF6 gas, providing complete sealing of all live parts and the switch, isolating them from external influences. This fully-sealed structure ensures reliability, safety, and maintenance-free operation.
