●Outline
Currently the process of urban and rural 10kV overhead insulated or less quickly, but work in the area of distribution transformer pole switches, surge arresters, wiring clips, pillars and other connecting parts of the multi-multi-point failure brought the run, security conditions are poor insulation, installation complexity, maintenance difficulty large and high costs, research and development pillars HY5WBG-17/50 type arrester devices, energy saving, cost savings, security, the United States faces, simplified lines and other features.
● Conditions of Use
1, ambient temperature: not higher than +50 ℃, not lower than -40 ℃;
2 Altitude: not exceed 1000m;
3, the wind speed: less than 35m / s;
4, the contamination level: Level III;
5, non-flammable, explosive and violent vibration places.
