Realizing the new structure of the lightning arrester and insulator integration, the product has both insulation support and lightning protection function. Using Daten current ZnO resistor, the current passing performance is improved to 130kA, which is more than 50% higher than that of the general lightning arrester, and the lightning trip rate is significantly reduced. Taking Hunan as an example, compared with the lightning trip rate of 8.0 times/(100km•a) before the application, the lightning trip rate is lower than 0.36 times/(100km•a) after the application of 35kV lines (under the condition of no ground wire).
The lightning protection section is provided with protection devices. When the lightning current exceeds the design value, the protection device action, effectively prevents the resistance sheet from lightning current damage and product damage. Simple and convenient installation, no special grounding treatment, to meet the requirements of a natural grounding tower.
