ZW7-40.5 outdoor high voltage vacuum short circuiter is applicable to 40.5kV, 50HZ three-phase power distribution systems, for switching on/off load current, overload current and short-circuit current, featured with safe and reliable performance, easy maintenance and long maintenance period. Filled with new type insulating material, there is no condensation on the outside of the arc extinguishing chamber and on the inner wall of the porcelain cover. The transformer arranged in mechanism case is a integral structure, which is easy to install. In addition, the oil, gas leaks and toxicity problems of other switches are avoided.
