• VSG-12 1600A Big Current Medium Voltage Fixed Type Solid Pole Vacuum Breaker 12kV

  VSG-12 indoor high-voltage vacuum circuit breaker is an indoor and outdoor switching device used in 12KV power systems. It is used as a protection and control unit for power grid equipment and power design of industrial and mining enterprises. It is suitable for switching loads of different natures and frequent operations. The occasion of breaking short-circuit current for the first time. The product adopts VSG module integrated spring operating mechanism. The primary part of VSG-12 can use a sealed pole to seal the vacuum arc extinguisher and the main conductive circuit parts into a whole, protecting the arc extinguisher from collision, dust and condensation. It has strong environmental adaptability and greatly reduces the cost of the arc extinguisher. operation and maintenance costs

  Features:
  1. Integration, modularization, miniaturization and lightweight;
  2. High reliability, long life, more stable performance;
  3. High degree of generalization, inventory and standardization of parts;
  4. High transmission efficiency and more reasonable design;

  Applying Ambient Conditions:

  1.Ambient temperature -25℃– +40℃
  2.The height above sea level: ≤1000 m
  3.Relative humidity: the average humidity of a day should be no more than 95％; the average humidity of a month should be no more than 90％.
  4.Saturated vapor pressure: the average pressure of a day should be no mare than 2.2kPa; the average pressure of a month should be no more than1.8KPa.
  5.Earthquake intensity: not exceed 8 degrees
  6.It should be Installed in the places without fire, explosion, serious filth, and chemical erosion and violent vibration.
