    Silicon Rubber Zinc Oxide Lightning Arrester 33KV Surge Diverter for Transformer Protection

    Silicon Rubber Lightning Arrest , Polymer Surge Diverter Protect for Transformer​


    Description:


    Polymer surge arrester is a device to protect electrical equipment from over-voltage transients caused by external (lightning) or internal (switching) events. Also called a surge protection device (SPD) or transient voltage surge suppressor (TVSS), thisclass of device is used to protect equipment in power transmission and distribution systems. (For consumer equipment protection, different products called surge protectors are used.) The energy criterion for various insulation material can be compared by impulse ratio, the surge arrester should have a low impulse ratio, so that a surge incident on the surge arrester may be bypassed, to the ground instead of passing through the apparatus.
