12kv/24kv/36kv Switchgear/ Switchboard/ Electrical Cubicle/ Sf6 Ring Main Unit Made in China

Short Description:

SSR-12 Environment protection gas insulated ring network switchgear

★SSR-12 environment protection gas insulated ring network switchgear is a kind of digital ring network switchgear with environment protection materials, full insulation, full sealing, economic price and convenient operation

★All conductive parts in the mechanism are installed in a sealed stainless steel air box, with dry air as the insulation main body, the main mechanism adopts vacuum arc extinguishing, and the disconnector adopts three position structure. The adjacent switchgear are connected by solid insulated bus.

★The secondary circuit adopts integrated control technology, supports data transmission function.
