Product Introduction

The SGC1-40.5C series gas insulated switchgear (C-GIS) is a new generation of switch products developed by XJ (Xiamen) Intelligent Power Equipment Co., Ltd. It adopts low-pressure SF6 (or N2) gas as the insulating medium inside, with vacuum circuit breakers and three-position switches as the main primary components, sealed inside the gas-filled compartment. The gas room is welded and formed from 3mm thick high-quality stainless steel plate and is not affected by the environment; it has the characteristics of reliable operation, safety guarantee, compact structural design, small footprint, maintenance-free, and long life.

The SGC1-40.5C series switchgear is a complete set of power distribution equipment for 40.5kV and 12kV three-phase AC 50Hz single busbar and single busbar sectional systems. It is mainly used for power reception, transmission, and starting of large high-voltage motors in power generation companies, small and medium-sized generators for power transmission, industrial and mining enterprise distribution, and power system substations, implementing control, protection, and monitoring.
