Product Description

GENERAL
The GN22-1.5kV/3150A disconnector is a large current indoor high-voltage disconnector, which is applicable to the rated voltage of DC1.5kV and is used as the opening and closing circuit with voltage and without a load in the power system. It adopts a two-step locking mode so that the dynamic and thermal stability of the switch is excellent and the operating force is small. New material processes such as epoxy resin, insulator, and tin or silver plating are adopted to make the switch conductive, small in size, and light in weight. Its outlet terminal is convenient for the connection with the vacuum circuit breaker, oil circuit breaker, and busbar, which can reduce the volume of the switch cabinet, reduce the over-current connector and reduce the cost.
