11kV Polymer Lightning-proof Pin Insulator With External Gap

With increasing rate of using insulator for power lines, the accidents caused by lightning, such as insulator wire break, switch tripping, and insulator flashover, happen frequently. How to prevent the accidents and improve the reliability of power supply is now the new topic of the power system that is badly in need of solution.

By cooperation with Jilin Power Limited Electric Power Research Institute and the department of Liaoning Power Limited, our company developed and manufactured the Lightning-proof pin insulators with external gap on base of extensive research and repeated tests. Lightning-proof pin insulators with external gap overcomes barriers of current lightning-proof devices on the areas of no arc blowout, stripping of external insulation lagging when installation, high voltage and current of unlimited reduce flow elements when discharging, instable discharging gap distance caused of climate influences fixed on conducting line. Lightning-proof pin insulators with external gap are a patent product and each index is higher than current lightning-proof devices.

● Lightning-proof pin insulators with external gap can replace pin insulators, set up conducting line directly and bending strength higher than pin insulators, the upper part of Lightning-proof pin insulators with external gap has acupuncture wire clamp which convenient to installation and has insulated protecting casing suitable to conducting lines of 352-2402.

● Lightning-proof pin insulators with external gap uses special reduce flow components burning out arc immediately and release micro-residual voltage at the same time, protects insulator and conduction line.

● Lightning-proof pin insulators with external gap uses white steel external discharging gap, sets up gap distance when production exit factory. And the device is not impacted of climate, discharge accurately, resistance to arc burning, discharge up to 10,000 times without damage, and do the long product life.

● When soil resistivity ≯30Ω, no grounding.
