The SRM6-12/24 series fully insulated and fully enclosed gas-filled metal switchgear (referred to as gas-insulated switchgear) is a completely sealed system, with all live parts and switches sealed in a stainless steel enclosure. The entire switchgear is not affected by external environmental conditions, ensuring operational reliability and personal safety, and achieving maintenance-free operation. By choosing expandable busbars, any combination can be achieved, realizing modularization. The expandable busbars are fully insulated and shielded, ensuring high reliability and safety. The gas-insulated switchgear can also provide industrialized automation solutions, forming the concept of intelligent switches and minimizing on-site installation and commissioning work.
All high-voltage live parts are located inside a stainless steel box, with the box shell being stainless steel sealed welding, filled with SF6 gas at a working pressure of 1.4 bar, and having a protection level of IP67. It can be installed in damp, sandy, dusty, salt-contaminated, mining, box-type substations, and any places where surface contamination is easily caused by air pollution without taking special preventive measures. No busbar cleaning or small animal prevention is required. Even the fuse chamber has a protection level of IP67. The expandable busbars are fully insulated and fully shielded to ensure they are not affected by external environmental changes and are maintenance-free.
The SRM6 series gas-insulated switchgear complies with the relevant provisions of standards such as GB3906, DL/T404, G131984, and JB/T3855.
