Product Description

Medium Voltage Gas Insulated Switchgear - 12kv, 24kv, 36kv, 40kv Rmu
 

Product Description
GRM type completely sealed completely insulated ring network switch equipment Gis, RMU ,Ring Main Unit (short for gas tank) is a new generation of modular switch equipment designed and developed by our company in combination with the characteristics of domestic and foreign products. In the same gas box, there are 6 buses (no line and outlet) units that can be configured at most. Each unit has its own function. When the system requires more than 6 units, two or more than two gas boxes can be connected in the form of extended bus bars. Each gas box can be arbitrarily extended on the left and right sides, and can be arranged arbitrarily according to different design schemes, so as to realize different configuration requirements.
