      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.
