12kv Medium Voltage Switchgear,Intelligent Electrical Solid Insulated switchgear Cabinet,RMU
Overview
The solid insulated switchgear is a completely insulated and sealed environmental protection device. The live parts are sealed in an epoxy resin insulation cylinder, the outer surface is coated with a grounding shielding layer, and the silicon rubber seals the bus. The plug-in solid insulation busbar is used to connect two adjacent switchgears. The entire switchgear is not affected by the external environment.
The solid insulation switch cabinet is composed of a vacuum load switch cabinet, a vacuum load switch fuse combination equipment cabinet and a vacuum circuit breaker cabinet. Suitable for three-phase AC 10kV, 50Hz single bus system, used for receiving and distributing energy equipment. With circuit control, protection, supervision and communication functions. It is suitable for airports, subways, large buildings, secondary substations and industrial and mining enterprises, etc. It is especially suitable for places with narrow space, harsh environment, high altitude and maintenance-free.
