Model:SSA 48
Buy Direct 48KV High Voltage Metal Gapless Arrester with Low Price made in China.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.
Wholesale hot sale Factory Direct 48KV High Voltage Metal Gapless Arrester with low price. Jecsany is a Direct 48KV High Voltage Metal Gapless Arrester manufacturer and supplier in China. SSA 48 Metal oxides surge arresters without gaps are designed to prevent probable damages in the case of typical surges in energy systems while it has no negative effect on energy systems in normal operation voltage. This special feature of gapless arresters originating from non-linear characteristics of metal-oxide varistors between voltage and current scales. The non-linear feature is much higher compared to SiC surge arresters.
