Features

◆Equipment for urban and rural power grid transformation can be matched with the controller to realize remote control, remote signaling, measurement and adjustment, realizing the "four remote" functions;

◆Flexible and convenient operation: It can store energy and open and close electrically, store energy and open and close manually, and can be operated at close or long distance;

◆Excellent breaking performance: 25kA rated short-circuit breaking current breaking times up to 30 times;

◆ Small operating power and high reliability: The operating power of the miniaturized spring operating mechanism (about 30W);

◆Reliable sealing performance: SF6 gas pressure is zero gauge pressure, and the sealing structure technology is adopted, the sealing performance is reliable and it is not easy to leak;

◆Unique way of inlet and outlet: Silicon rubber casing is used to make the insulation distance between the terminals sufficient and the external insulation performance is excellent;

◆Excellent safety performance: An explosion-proof device is installed on the top of the box. Even if an internal failure occurs, no high-temperature gas or splashing will leak out;

◆Flexible installation method: It can be installed by hanging on the pole or sitting on the pole.
