      1. General
       

          The VW1-12 series vacuum circuit breaker adopt the latest and mature technology of automatic Pressure Gelation (APG) to embed the vacuum interrupter and connection terminals within resin. The vacuum interrupter is casted in the resin, which makes the circuit-breaker poles particularly sturdy and reliability and protects the interrupter against shocks, accumulation of dust and humidity. Thanks to the embedded pole design, the distribution of electrical field of the pole is much even than in the assembly pole vacuum circuit-breaker, so the insulation strength of VW1 series MV embedded pole vacuum circuit-breaker is improved dramatically.

       
      2. Working Condition
       
      •     Guarantee the ambient environment temperature within -15~+40, the daily average      temperature not exceed +35;
      •     Daily average related humidity not exceed 95%, monthly not exceed 90%;
      •     The altitude not exceed 3000m above the sea level;
      •     Earthquake intensity is not more than 8 degree horizontal acceleration.
      •     The ambient air without contamination of erosion and combustible gas, vapor, etc.

       

      3. Characteristics:
       

      • Suit for width switchgear of 650mm,800mm,1000mm.
      • Unique embeded-pole design.
      • Upgraded into an intelligent embeded pole CB with monitoring on-line function device, which solves abnormal heating problem.
      • Options for embedded small size or general size floor type.
      • All copper contact arms with silver plated.
      • Simple spring operating mechanism,maintenance free in 10,000 times of operation.
      • Leading screw driving mechanism equipped with overruning clutch makes movements smooth and easier.
