GW4A-40.5W Series

Indoor Single Phase DC Isolation Switch

GN22-1.5kV/3150A isolaion switch is a high current indoor high-voltage isolaion switch, suitable for rated voltage DC1.5kv, andused as a circuit breaker in power systems with voltage and no load. It adopts a two-step locking method, which ensures excellenthermal stablity and low operating force of the switch, lt adopts new materials and processes such as epoxy resin and insulators.as well as tin or siliver plating, to improve the conductivity of the switch, make it smal in size, and lightweight.lts output terminals areeasy to connect with vacuum circuit breakers, oil circuit breakers, and busbars, which can reduce the volume of the switchgearreduce transition ioints.and lower costs.
