10KA Polymer Surge Protection Varistor Lightning Arrester 18KV

10KA Medium Voltage Silicone Housing Polymeric Metal Oxide ZnO Surge Lightning Arrester for Transformer

Polymeric Surge Lightning Arrester:

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.
