Description:
High Voltage Varistor: 1. Low residual voltage ratio; 2. Highcurrent withstand capability; 3. Stable ageing performance.High Voltage Varistor of 72mmDiameter for Class 3 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.
