IHM-RMUA Air Insulated Switchgear

IHM-RMUA Air Insulated Switchgear adopts dry air as the insulating medium. The isolating switch and the arc extinguishing chamber are completely sealed in a gas tank filled with dry air. The gas tank is made of stainless steel and is automatically welded by the robot. The protection level of the gas tank reaches IP67. IHM-RMUA air-insulated switchgear does not use any greenhouse gases or harmful gases. It is compact, small , modular, and maintenance-free.

IHM-RMUA Air Insulated Switchgear consists of three types of switch module: Module V (circuit breaker unit), Module C (load break switch unit), and Module F (load break switch and fuse combination unit), which can be flexibly combined and expanded as per customer requirements.
