12kV Fully insulated inflatable ring switch equipment

RM-12(C)/630-25 Gas Filled SF6 metal-enclosed fully insulated series ring main unit is widely used in 10kV/6kV power distribution systems,and is the preferred switch product for all types of substation and distribution systems for urban and rural users. The switchgear is a modular unit mode, which can be combined according to different purposes; there are two types of fixed unit combination and expandable unit to meet the flexible use of compact switchgear in various substations.

RM-12(C)/630-25 gas filled ring main unit is a completely sealed system, and its live parts and switches are enclosed in a stainless steel body. The entire switchgear is not affected by external environmental conditions, thereby ensuring operational reliability and personal safety,so as to achieve maintenance-free. By choosing an expandable bus, any combination can be made to achieve full modularity. The safety insulation and shielding of the extended bus bar ensure reliability and safety. RM-12(C)/630-25 gas filled ring main unit can also provide IV-based automation solutions, forming the concept of intelligent switches, and minimizing the workload of on-site installation and commissioning.
