●Outline
Piercing the outer gap arrester suitable for distribution 10kV overhead insulated wire, which uses a patented puncture entered the arc head structure, penetrate wire insulation electrical connection; arc does not arc and lightning top of the lower head in contrast, the formation of a series 60 ~ 130mm spacing of the outer discharge gap, and its distance from the lower portion of the arrester by the relative movement of the two mounting plates to be adjusted. Under normal conditions, the high resistivity sheet and the discharge gap arrester blocking the action; only exceed the lightning overvoltage occurs, the breakdown of the discharge gap to form a short-circuit path, the continuous frequency gap between the arc will burn out the release over-voltage energy to protect the wires from burns. After the release voltage, high resistance arrester varistor recovery gap discharge stops.
● Conditions of Use
1, ambient temperature: -40 ℃ ~ +50 ℃;
2, altitude less than 2000m;
3, the power frequency is 50 ~ 60Hz;
4, the maximum wind speed does not exceed 35m / S;
5, 8 degree earthquake intensity and for the following areas.

● Installation Buju
1, choose the right type of installation based on the actual needs and puncture-type series outer gap arrester.
2, the first mounting plate in an ordinary steel pin insulators.
3, select the appropriate location of the puncture arc head mounted on a wire, divided evenly tighten the bolts until the last moment to twist off the cap, while the teeth should be deep puncture the insulation layer and the outer layer should be close to the wire on the online slots. (Note: There is a little grease on the insulation piercing teeth, used to enhance water resistance, do not rub off during installation)
4, the installation of the insulation cover, the electrical contact portion is fully wrapped in the insulating material of the cover exposed, and improve the safety line.
5, adjust the distance between the head and puncture arc arc on the head arrester installed below the fixed distance between the two arresters (specific size relationships are shown in Table 2)
6、运行过程中，特别是恶劣天气后应及时循环检查产品是否遭受雷击放电。如有发现雷击受损严重的，应及时更换。 |
