The SRM6-12 SF6 Gas Insulated Fully Enclosed Ring Network Switchgear is a metal-clad, SF6 gas-insulated switchgear with a modular unit design. It consists of two main categories: fixed units and expandable units. The equipment can be composed of modules such as load switch units, load switch-fuse combination units, vacuum circuit breaker units, and busbar incoming units. It is a completely sealed system, with live parts and switches enclosed in a stainless steel body. The entire switchgear is unaffected by external environmental conditions, ensuring reliable operation and personnel safety, and it is maintenance-free. By selecting expandable busbars, any combination can be achieved, reaching full modularity. The expanded busbar is safely insulated and shielded, ensuring reliability and safety. It is used in power systems with three-phase AC 50Hz and rated voltages from 6kV to 24kV, and can also provide automated solutions for TV-based systems, embodying the concept of intelligent switches and minimizing on-site installation and debugging efforts. It is widely used in industrial and civil cable ring networks and power end-user projects. The SRM6-12 SF6 Gas Insulated Fully Enclosed Ring Network Switchgear complies with standards such as GB3906, DL/T404, GB/T11022, and IEC298.
