GW9-12/24/36(W) outdoor AC high voltage disconnect switch ( disconnect switch for short)is used to open and close circuit with voltage but no-load 50/60Hz,6.6~24kV power system, anti-pollution type suitable for serious pollution area.
1. Altitude: ≤ 1000m;
2. Ambient temperature: -25 ~+40℃ ;
3. Wind speed: ≤ 35m/s;
4. Earthquake intensity: ≤ 8 grade;
5. Applicable occasions of normal type switch should be free from chemistry aggravation, dust and other volatile & caustic thing.
GW9-12/24/36(W) disconnect switch is single type.
1. This series switch have normal and anti-pollute two difference models, it composed of frame, support insulator, with power partand operating mechanism.
2. Each pole have two pieces blade, there is press spring near the contactor base and have adjusted nut to keep good contact press, there is a support structure on the blade, it can be locked after closing, so it will not be closing b y itself u nder any c ondition, under normal or short-circuit condition, it can ensure the reliable performance of dynamic and thermal stability.
