INTRODUCTION

Silicone Rubber Insulated Zinc Oxide Over-voltage Protectors for Over-head Distribution Lines
and Aerial Insulated Cables Rated Voltage from 1kV up to 35kV

Features

■   Effectively prevent over-head lines and insulators flashover or broken down
■   Superior water penetration protection from one-piece molding
■   Meet the strictest standard in the world---IEC 99-4
■   Elastic silicone rubber construction for lightness with longevity

Applications

Apply to over-head distribution lines and aerial insulated cables rated voltage from 1kV up to 35kV for preventing over--head lines operation safety from lighting over voltage, operating over voltage as well as over voltage flashover or broken--down.
