Type Disconnector 12KV 24KV 36KV GN24-12 10KV disconnector
Product Description
Product Description
GN24-12 (indoor),used for in the three-phase AC 50/60Hz,rated voltage 12KV power system, comply with CS6-1tyepe manual operation mechanism which can be used for opening and closing loading current overloading current and short-circuit.Some type can also be used at heavy pollution or high altitude area.
Product feature
1. Scientific design and innovative structure.
2. Contacting points distribute on two planes, small operating moment, and release pressure to small and easy adjustment.
3. Improved driving and conducting part.
4. Column moving contact that can decrease operating strength and ensure reliability of circuit conduction.
Service Conditions:
1. Altitude: 1000m;
2. Ambient temperature: -25 ~+40 ;
3. Relative humidity: daily average 95 , monthly average 90 ;
4. Earthquake intensity: 8 degree;
5. Applicable occasions should free from inflammables, explosives, corrosives and severe vibration.
