SF6 inflatable ring network cabinet

Back to superior

Product name: SF6 inflatable ring network cabinet

product description

All high-voltage live parts of the SF6 inflatable ring network cabinet are located in a stainless steel cabinet with an IP67 protection rating. It can be installed in any place where air pollution can easily cause surface flashover without special precautions. It has a reliable pressure relief channel to ensure operational reliability and personal safety, and to achieve maintenance-free during the life cycle.

Performance characteristics

Gas box is filled with SF6 gas, compact structure, small footprint

Can be used alone or integrated with secondary intelligent power distribution terminal equipment

Adopt laser welding full-sealing technology, synchronous vacuum helium leak detection, strong environmental adaptability

6 modules, more than 6 modules can be configured, and expansion bus connection can be used

Can realize different primary power distribution schemes
