Lightning Arresters/Surge Arresters
We are leading surge arresters manufacturers, suppliers and exporters. Lightning arresters/surge arresters are are made from high-quality raw materials and are used to safeguard electrical equipment from medium and high voltages.
Application
A lightning arrester/Surge Arrester is a device used on electrical power systems to protect the insulation of transformer and conductors of the system from the damaging effects of lightning. The typical lightning surge arrester has a high-voltage terminal and a ground terminal. When a lightning surge (or switching surge, which is very similar) travels along the power line to the arrester, the current from the surge is diverted through the arrestor, in to earth.
