switchgear

Description

SF6 gas insulated switchgear ring main unit for the secondary distribution network. We can be supplied in 10 different configurations suitable for most switching applications in 12/24/36 kV distribution networks. It is have Non-extension and extension able modular compact switchgear, they represent a complete solution for 12/24/36 kV secondary distribution networks. FGRMU and FGRMU-plus have identical user interfaces. FGRMU is a completely sealed system with a stainless-steel tank containing all live parts and switching functions. A sealed steel tank with constant atmospheric conditions ensures a high level of reliability as well as personnel safety and a virtually maintenance-free system. The FGRMU concept offers a choice of either switch-fuse combination or circuit-breaker with relay for protection of the transformer. FGRMU can be supplied with an integrated RTU remote control and monitoring unit.
