Lightning Surge Arrester 

Description

When lightning surge arrester is under normal working voltage, the current flowing through the arrester is only micro-ampere, which is equivalent to an insulator. When it is over-voltage, the resistance of the arrester is drastically reduced, so that the current flowing through the arrester can be instantaneously increased to kiloampere, the arrester is conducting state, releasing the over-voltage energy, thereby effectively limiting the over-voltage damage to the transmission equipment.

Advantage of Lightning Surge Arrester

1. Simple structure, low cost and stable performance.

2. After the action of lightning over-voltage, there is no power-flow current, so that the energy passing through the arrester is greatly reduced, thereby extending the working life.

3. The zinc oxide resistor has a large flow capacity, which improves the operational load capacity and current withstand capability of the arrester, the resistor can be placed directly in the SF6 combined electrical appliance or in the oil-filled equipment.
