Product Description

Principle and characteristics

With the popularization and application of insulated overhead distribution lines, necessary and effective lightning protection measures can reduce the phenomenon of lightning breakage and insulator burning caused by direct and induced lightning. The product can cut off the continuous current of power frequency rapidly through the synergistic action of arc rod, zinc oxide arrester element and discharge gap. Effectively limit lightning overvoltage, avoid lightning break of wire and reduce lightning trip times. The power supply will not be interrupted and the power supply quality will not be affected.
