40.5kV 1250A

SSOD double column series outdoor column isolation switch (hereinafter referred to as isolation switch) is a hook rod operation type isolation switch, the knife has a self-locking device. This series of isolating switches is suitable for the isolation of 12 ~ 40.5kV overhead lines, and the opening and closing operations are carried out under no load. The main function is to isolate the voltage during equipment or line maintenance to ensure safe operation. Use with circuit breakers or load switches and provide a safe visible break for the line.

Key words:

40.5kV 1250A
