  • Detailed Description
  • GW5 series Outdoor High Voltage Disconnectors consists of three single phase, V type for each phase, symmetrical angle  is 50°, disconnect switch is made  of pedestal, post insulator and electric part. They  are used in no-load condition to switch off the electric circuit and isolate  electrical equipment, such as high voltage bus, Circuit Breaker etc, and high  voltage line up to 252kV power system.

     

    GW5-40.5/72.5/126/252 outdoor high voltage disconnecting switch is used to make or break high voltage circuit in rated voltage 40.5kV, 72.5kV, 126, 252kV, AC 50/60Hz electric system. It can open and close small capacitance and inductive current. This disconnecting switch accords with standards: IEC62271-103 High voltage switches. GB1985: AC High voltage disconnect switch and Earthing Switch and IEC 60694 & GB/T11022: Common technical requirements of HV Switchgear and control equipment.
