Product Desciption

FZW28-12 type pole mounted high voltage AC vacuum load switch is suitable for installation areas on column, and has manual and electrical operation functions. Switch main body is improved based on the basis of VSP5-12 from Japan Toshiba, and is more suitable for our country's distribution network use requirements. This switch is maintenance free load switch, and use vacuum extinction and SF6 gas for insulation medium between ground and phase, it is suitable for 10kV distribution line user incoming demarcation point of responsibility, and also suitable for branch line connection point that meets requirements.

Switch use full insulation, full seal structure, and high voltage part, low voltage control circuit and operation mechanism are all sealed inside switch cabinet. And inside cabinet, there is SF6 gas, switch main circuit outlet terminal is protected by insulation cable.

Operation mechanism skillfully combines spring energy storage mechanism with electromagnetic mechanism which has free release device, to enable equipment to have manual/auto operation functions and switch operation more flexible. This enables reliable open for switch when under voltage loss situation.

Switch is mounted by suspension or sear type, which makes it more convenient and flexible to install on the pole.

Switch has distribution auto control interface. It can realize feeder automation function of distribution network by adding intelligent control box.
