GW10 type isolating switch
The GW10 type isolating switch has a single arm vertical telescopic structure for its main switch blade, forming a vertically oriented insulation single break in the open state. It has the smallest phase to phase distance and longitudinal length, and is widely used in power systems.
(1) Adopting a clamp type structure, the static contact has a large contact range and clamping force;
(2) The conductive part is made of high-strength aluminum alloy material, which has high mechanical strength, light weight, and strong anti-corrosion ability;
(3) The conductive key uses a soft connection structure, which is simple in structure and easy to install;
(4) The transmission part adopts composite shaft sleeves, which have good self-lubricating performance, low friction, reliable mechanical transmission, low operating force, high strength and toughness of the operating lever shaft, and excellent corrosion resistance.
