• GW1 Outdoor AC High Voltage Isolation Switch With Ceramic Insulating Post

  GW1 outdoor AC high-voltage isolation switch is suitable for installation on outdoor high-voltage power distribution equipment line for cutting off the line and converting the line when there is voltage and no load. This product is a three-phase electrical appliance composed of three separate single-pole disconnect switches. Each single-pole disconnecting switch has the same components, such as base pillar insulator, front and rear static contacts, gate knife and arc angle.

  The isolating switch consists of three identical single-pole isolating switches, which, when installed, are formed into a single unit by a tube connecting rod and are equipped with a CS8-1 manual operating mechanism. Each single-pole disconnecting switch has a separate iron frame with two pillar insulators mounted at both ends, on which contacts are fitted. In the middle of the iron frame, there is a rotating shaft, with the help of the tie rod insulators to make the knife gate split and close. GW1 switch is a double-pillar outdoor high-voltage disconnecting switch consisting of three single-pole, the switch is a unidirectional opening type, which consists of a base, insulators, contact knife guides and a conductive part, with two pillar insulators for each pole fixed on the two sides of the base, and in the middle of which there are tie rod insulators, a crutching arm and a rotating shaft to open or close the switch, which is available with a The switch can be equipped with an anti-theft operating mechanism or with a common type operating mechanism.

  Environmental conditions:
  1. The altitude does not exceed 2000m or less.
  2. Ambient temperature upper limit +40°C, lower limit -30°C in general area.
  3. Wind pressure not exceeding 8 degrees.
  4. Seismic intensity does not exceed 8 degrees.
  5. Ice thickness not more than 1mm.
  6. No frequent and severe vibration in the installation place.
  7. Ordinary type installation place should seriously affect the isolating switch insulation and conductive fatigue of gas, steam, chemical deposition, salt spray, dust and other explosive and corrosive substances.
  8. Anti-fouling type is suitable for heavily polluted areas, but should not be used to induce excessive fire and explosion and other substances.
