Product Features

The composite outer casing metal oxide arrester uses a metal oxide varistor sheet with excellent volt - ampere characteristics as the core body, and adopts a silicone rubber composite material which is resistant to electric corrosion, oxidation resistance, good elasticity, high mechanical strength and primary integral compression molding as an insulating jacket. The advantages of both organic composite insulation and metal oxide varistor are concentrated. The product has the advantages of small volume, light weight, no damage, easy to transport and install, water repellency and strong stain resistance, overall model compression molding, no air gap, good sealing performance, stable performance, reduced operation and maintenance, moisture proof and explosion proof. No risk of explosion, suitable for use in switch cabinets.

Place of use

The series of composite jacket metal oxide arresters are mainly used to protect distribution transformers, box power stations, cable heads, on-column switches, protective substation electrical equipment, and to suppress the re-ignition overvoltage generated by vacuum switch or oil switch switching capacitor bank. Protect the capacitor bank from over -current damage and protect the insulation of the generator, engine, and motor neutral from atmospheric overvoltage and operating overvoltage.
