11kv~24kv high voltage automatic switch auto recloser sectionalizer

Product Description

Benefits:

1. Modular spring operating mechanism, easy installation and maintenance

2. New vacuum interrupter of high vacuum and ultra-low resistance,stronger breaking capacity,insulation recover faster, lower contact resistance

3. Item models fully cover the rated current from 630A to 4000A and the rated breaking current from 20kA to 50kA

4. Two installation type: fixed-type, draw-type

5. With wrong operation prevention interlock,keep risks away

6. Easy control and low maintenance

serving conditions:

1.Ambient temperature: -10 Deg. C to +40 Deg. C

2. Altitude: 1000m.

3. Humidity: 95%

4. Saturated vapor pressure: daily average≤2.2 kPa, monthly average≤1.8 kPa.

5. Earthquake intensity: ≤8.

6. Following situation will harm circuit breaker: fire, explosion hazard, pollution class above 2, chemical corrosion, intense vibration.
