Pkj-10/35 type distribution network copper plated ball type adjustable overvoltage protection device (lightning protection)

1. Product introduction The adjustable gap lightning protection device of the distribution line is connected in parallel at the two ends of the insulator of the distribution line, and the lightning discharge voltage of the gap is adjusted to be slightly smaller than the impact flashover voltage of the insulator. Under the action of lightning overvoltage, the gap acts and the lightning is applied. The overvoltage leaks into the earth to protect the insulator from damage. If it is an insulated wire, it can prevent the arc from occurring between the insulated wire and the ground and blow the insulated wire.

Product Description

1. Product introduction
The adjustable gap lightning protection device of the distribution line is connected in parallel at the two ends of the insulator of the distribution line, and the lightning discharge voltage of the gap is adjusted to be slightly smaller than the impact flashover voltage of the insulator. Under the action of lightning overvoltage, the gap acts and the lightning is applied. The overvoltage leaks into the earth to protect the insulator from damage. If it is an insulated wire, it can prevent the arc from occurring between the insulated wire and the ground and blow the insulated wire.
The product consists of upper and lower fixed fittings, wire spherical electrodes, grounded spherical electrodes and adjustable fixing brackets.

2, the main features
◆ Ball-type electrode lightning impulse discharge voltage stability
◆ When the arc gap is burned, the arc is evenly distributed on the surface of the spherical electrode, and the arc surface is large. Therefore, the electrode surface is not melted like the rod gap, and the burr is formed to reduce the discharge voltage of the discharge gap.
◆ The ball gap can pass the 100KA lightning current will not be melted, which is far better than the rod gap.
◆ Adjustable gap to eliminate the effects of contamination and insulation degradation
◆ High-quality steel copper plating is anti-corrosion, anti-corrosion effective period can reach 20 years
◆ Simple structure, convenient installation, easy inspection and inspection, basically no maintenance
