Product Description

General

 

Outdoor high-voltage AC single-phase isolation switch (hereinafter referred to as "isolation switch"), for the 1 0kV line under the condition of voltage and no load, and the maintenance of high-voltage bus, circuit breakers and other electrical equipment and live high-voltage line for electrical isolation.

Service environment

 
  • The altitude does not exceed 1000m.

  • The ambient air temperature: Maximum+40°C; Minimum:-30°C,Paramos-40°C.

  • The wind pressure does not exceed 700Pa.(corresponding to 34m/s wind speed).

  • The earthquake intensity does not exceed 8 degrees.

  • The working situation hasn't frequent violent vibration.

  • The installation site of ordinary type isolator should be kept away from gas, smoke chemical deposition, salt-spray fog, dust and other explosive and corrosive maters that affect seriously insulation and conduction capability of the isolator.

  • Pollution-proof type isolator is applying to severe filthy conduction area; however, it shouldn't be any explosive matters and matters causing fire

 

Key Feature

  • It is a single-phase structure, and each phase is composed of a bottom frame, a pillar insulator, a knife and a contact.

  • The upper end of the knife is equipped with a fixed pull button and a self-locking device for opening and closing the insulated hook rod.

  • Silver brazed contact with new technology
