Bitai electric  offers Metal Oxide Varistor(MOV) for most economical ,the largest selection for low voltage, distribution-class, riser pole, intermediate-class, and station-class surge arresters for overhead and underground applications in the industry.  

          ZnO blocks  are generally employed in AC and DC power systems, due to the  protection  of energy program from the lightning impulse. 

          The M.O.V. Direct Connect Arrester combines metal (zinc) oxide varistor technology in a premolded rubber elbow to provide overvoltage system protection in an insulated, fully shielded, submersible, deadfront device.
