YH5W 10KV 15KV 20KV 30KV 66KV Metal Oxide Surge Arrester

1. YH5W Type Lightning Arrester Metallic Zinc-Oxide Arrester Zinc Oxide Surge Arrestor

Metal oxide arresters are the most advanced protection devices for current over-voltage. They are widely used in power generation, power transmission and distribution systems to protect the insulation of electrical equipment from overvoltage.

The organic jacket metal oxide arrester is a scientific research achievement combining the advantages of organic insulating material and traditional porcelain sleeve metal oxide arrester technology. It not only has the advantages of porcelain sleeve metal oxide arrester, but also has good electrical insulation performance and dielectric. High strength, anti-leakage, anti-corrosion, heat resistance, cold resistance, aging resistance, explosion-proof, water-repellent, good sealing performance.
