Wind speed / pressure (outdoor): 34m/s  /  700Pa

Pollution level: e-level

Icing thickness: not more than 20mm

Humidity: average daily relative humidity, not more than 95%, average monthly relative humidity not more than 80%

Earthquake resistance: horizontal acceleration 0.3m/2, vertical acceleration 0.15m/s2

Safety factor: sinusoidal resonance three cycle wave, safety factor above 1.67.

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.
