Lightning-proof pin insulator with external-set gap

1. heigher bending strength 2. to protect insulator and conduction line 3. white steel external discharging gap

Lightning-proof pin insulators with external series 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 series gap are a patent product and each index is higher than current lightning-proof devices.

1. The device 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 series gap has acupuncture wire clamp which convenient to installation and has insulated protecting casing suitable to conducting lines of 352-2402.

2. The device uses special reduce flow components burning out arc immediately and release micro-residual voltage at the same time, protects insulator and conduction line.

3. The device 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.

4. While soil resistivity ≤30Ω, no grounding.
