YOUR POSITION: HOME >PRODUCTS >Silicone Rubber Insulated Zinc Oxide Surge Arresters
   INTRODUCTION
    Silicone Rubber Insulated Zinc Oxide Surge Arresters Applied to Transmission Systems Rated
    Voltage from 35kV up to 220kV

 
    Features    
   Type Specifications
 ■     Effectively restrain system transient over-voltage
          level
 ■     Superior water penetration protection from one-
          piece molding
 ■     Meet the strictest standard in the world---IEC 99-4
 ■     Elastic silicone rubberconstruction for lightness with
          longevity
 ■     Excellent mechanical strength, exploding resistant          and  safe to environment
 ■     Not only used as surge arrester, but also used as
          post insulator at the same time
 
 
  Applicable Fields: Z for Substation   R for Electric Capacitor  
                                        S for Distribution   G for Ring-main Unti
                                        D for Electric Generator and Motor    J for Neutral Grounding
                                        T for Electric Railway   X for Transmission Line
