12kV Gas-Insulated Switchgear

The TL series 12kV gas-insulated switchgear is a compact, fully insulated, modular distribution switchgear, suitable for 12kV and below power distribution networks. It uses SF6 gas as the insulating and arc-extinguishing medium, with a fully sealed structure and a five-interlock protection system, ensuring high safety, reliability, and an extended service life.

Due to its compact design and small footprint, it is especially suitable for locations with limited installation space, such as small distribution substations, urban residential areas, railway tunnels, and airports.

Taili Electric always puts product quality first, using high-quality components to ensure product stability and reliability.
