6.6kV power distribution lightning arrester for heavy salt resistance
Otowa Electric Industry Co., Ltd.
About This Product
■Features
1.Excellent stain resistance properties
-Double-skirted insulator structure prevents contamination from progressing and almost no leakage current flows.
・Even when contaminated, there is almost no effect on the discharge characteristics.
2.No follow current due to non-linear resistance of ZnO element
Suitable for protection against severe lightning surges.
3.Excellent protection performance
Since the limiting voltage is sufficiently lower than the JEC standard value, the protection range is expanded.
4.Can be used for a long time without maintenance or inspection
Completely sealed structure requires almost no maintenance or inspection.
