30KV 5KA Porcelain Surge Arrester

Find a huge selection of 30KV 5KA Porcelain Surge Arrester from China at Jecsany. Provide professional after-sales service and the right price, looking forward to cooperation.The zinc oxide surge arrester is the most advanced over-voltage protector in the world. Due to make the resistor disc of core component mainly adopt zinc oxide arrester. Compared with the conventional siliconcarbide arrester, this prescription of the product improves greatly the volt-ampere characteristics of the resistor disc and increase through current capability at over-voltage so as to bring a rad local-changes for the characteristics of the arresters.

Product Description


Wholesale 30KV 5KA Porcelain Surge Arrester made in China. Jecsany is a 30KV 5KA Porcelain Surge Arrester manufacturer and supplier in China.  Y5W-30 Metal-Oxide lighting arrester is one kind most world advanced over voltage protector at present. Due to its core components of resistance applying ZnO and othermetal oxide to make of, comparing with traditional carborundum arrester, it improves greatly V-A characteristics of Resistance, increases the getting trough abilty of resistance, thereby it brings fundamental Under normal working voltage, the current passing arrester only A class,when bearing over voltage, the excellent non- linear V-A features of arrester would make effect, the current passing through the arrester increase high to thousands of Ampere instant,the arrester is under getting through state, to release over-voltage energy, therefore it effective limits t he damage to power transmission equipment due to over Voltage.
