product detail
GW4-12 Outdoor disconnector（isolate switch）12kv
GW4-12 outdoor AC high voltage disconnect switch (disconnect switch for short) is used to open and close circuit with voltage but no-load 50/60Hz, 12kV power system. It accords with standards of IEC129-1984 AC Disconnect Switch and Earthing Switch and GB1985 and other relative standards.
Service condition:
1. Altitude: ≤2000m;
2. Ambient temperature: -25℃~+40℃;
3. Wind speed: ≤35m/s;
4. Pollution degree: ≤III;
5. Earthquake intensity: ≤8 degree;
6. Applicable occasions should free from inflammable, explosives, caustic gas .
Products with special requirements, specifications and dimensions that need to be improved can be designed and manufactured according to user requirements.
