12kv Medium Voltage Switchgear , Electrical Solid Insulation Mv Switchgear Rmu
12KV Medium Voltage Switchgear Solid Insulation Switchgear RMU
Overview
GXGT1-12 Solid Insulation Switchgear is an environmental equipment which is fully insulated and sealed, live parts are sealed in epoxy resin insulating cylinder with earthing shielding painted on outside surface and silicone rubber sealing busbar. Plug-in type solid insulation busbar is used to connect two neighbor switchgears. Whole switchgear is not influenced with external environment.
GXGT1-12 solid insulation switchgear consists of vacuum load switchgear, vacuum load switch-fuse combination equipment cabinet and vacuum circuit breaker cabinet. It is suitable for three phase AC 10kV, 50Hz single busbar system for acceptance and distribution of energy equipment. It has control, protection, supervision and communicating functions for circuit. It is applied in airport, subway, large buildings, secondary substation and industrial and mining enterprises, etc, especially for the place with narrow space, bad environment, high altitude and request for maintenance-free.
