GW1-10 type outdoor AC high voltage isolation switch is composed of three identical single-pole isolation switches.
In the installation, the three poles are formed into a whole by the pipe connecting rod, and the CS8-1 manual operation mechanism is used.
Each single-pole isolation switch has a separate iron frame with two post insulators installed at both ends and contacts installed on them.
There is a rotating shaft in the middle of the iron frame, and the tool brake is closed by means of a tie rod insulator.
