Description:
ZnO Varistor: 1. Low residual voltage ratio; 2. High currentwithstand capability; 3. Stable ageing performance.4.5kV-5kA ZnO Varistor for Coreof Surge Arrester
Brief
Yikun Electric isspecialized in manufacturing metal oxide varistor blocks for surgearrester ranged from 32mm diameter to 115mm diameter withalternative height.
Our MOV block canwithstand 65kA and 100kA high current impulse and the specifiedlong duration current impulse.
The surge arresterassembled by our blocks has passed KEMA type test and been exportedto many countries such as Yugoslavia, Turkey, India, Pakistan,Iran, Korea, Japan and Argentina.
