It is a completely sealed system, all live parts and switches are sealed in a stainless steel housing. The entire switchgear is not affected by external environmental conditions, thereby ensuring operational reliability and life safety, and achieving maintenance-free. By choosing an expandable bus, any combination can be achieved to achieve modularity. The extension bus is completely insulated and shielded to ensure high reliability and safety. The inflatable cabinet can also provide industrialized automation solutions, forming the concept of intelligent switches, and minimizing the workload of on-site installation and commissioning.

    All high-voltage live parts are located in the stainless steel box, the box shell is stainless steel sealed and welded, filled with SF6 gas with a working pressure of 1.4Bbar, and the protection level is IP67. It can be installed in damp, sandy, dusty, salty, mines, box-type substations and any places where air pollution is prone to surface pollution without taking special precautions. There is no need to clean the bus and prevent small animals. Even the fuse room has an IP67 degree of protection. The extension bus is fully insulated and fully shielded to ensure that it is not affected by changes in the external environment and is maintenance-free.
