GW5 series outdoor high-voltage isolation switchDetailed product description：

The GW5 series outdoor high voltage isolation switch is a three-phase AC 50HZ outdoor high voltage electrical device used for voltage and no-load division circuits.  
The GW5 series outdoor high-voltage isolation switches are divided into two types based on their external insulation capacity: ordinary type and pollution resistant type. Both types can be equipped with grounding switches, which can be single grounded or double grounded. Grounding switches are further divided into Type I and Type II based on their ability to withstand the thermal effects of short-circuit currents.

Structure:
The GW5 series outdoor high-voltage isolation switch is equipped with a CS17 manual operating mechanism, which is equipped with an electromagnetic lock and an interlocking board to achieve interlocking between the main switch blade of the isolation switch and the grounding switch.
