Outdoor Vacuum Disconnecting Load Switch

General:

 It uses new insulation structure design and vacuum explosion chamber. After switching off, the load switch has an obvious visible fracture. It also has functions of disconnecting switch. Additionally,with big switching capacity and no oil, long electricity life and non maintenance, it will not pollute environment and explode.

Service Environment

• Ambient temperature :+40℃~-40℃, daily temperature difference :25K;

• Altitude: no more than 2000 meters;

• Wind pressure does not exceed 700Pa(equivalent to 34m/s wind speed);

• Amplitude: no frequent violent movement, seismic intensity does not exceed 8 degrees.

• Air pollution level 3;

• Condensation may occur during periods of high humidity when the temperature drops;

• Not applicable to places with fire, explosion, chemical corrosion and violent vibration.

• Key Feature

• Using vacuum arc extinguishing chamber, no explosive danger.
  

• The isolation knife is connected with the three-phase vacuum interrupter, and there is an obvious isolation fracture when the brake is opened.

• Can pull the brake with load, safe and reliable, long electric life.

• All parts of the body are made of stainless steel, and the bottom frame is made of stainless steel or carbon steel with hot dip galvanizing and ultraviolet protection coating to ensure the normal operation of the body in the outdoor environment.

• The installation mode is double rod type, electric operation is the main, and manual or remote control operation can also be used.

• Widely used in rural urban network, railway and other configuration power line transformation.
