Info:Main features:l The product adopts the overall structure of a single column,lightweight, with simple structure.l It canceled the internal equalizing capacitor,improved the grading ring structure, Measured Non-Uniform voltage coefficient is less than 10%,with high reliability.l It adopts double sealing structure. The core encapsulates by molded silicone rubber which solves the sealing problem of porcelain housed products.l Nitrogen Purged for drying to prevent inner flashover, with higher inner insulation level than air insulation.l It has pressure release structure.l Zinc oxide varistor as its core element has a good pressure ratio and consistency, with 2500A flow capacity.l The creepage distance of porcelain housed produces is wide which is suitable in IV level heavy pollution areas.
