Product Description

Production Description

The zinc oxide varistor installed within arresters, it has excellent nonlinear volt-ampere characteristic. In normal operating voltage, it displays large resistance, its leakage current is only microampere grade. While over-voltage appear, it translates low resistance immediately, releases energy and limits over-voltage range, it resumes large resistance immediately after over-voltage disappear, and ensures electric power system running safely.Wortai Electric has manufactured the zinc oxide varistor for more than 20 years. The quality of our products is one-up in china, its residual voltage ratio is little and ageing performance is excellent.
