1. VITZROTECH LA & SA (Lightning Arresters & Surge Absorbers) INTRODUCE


 1-1 LA (Lightning Arresters) 


  ● VITZRO TECH Polymer Type Lightning Arrester is the 18kV, 5kA product that is

      used at distribution line and general consumers. In order to prevent the explosions due  

      to humidity absorption deterioration, the major faults that are generated at the existing  

      porcelain-type lightning arrester, winding is done using FRP insulators. The interface  

      between the FRP insulator and high-molecular rubber housing is treated and both  

      ends of polymer-type lightning arrester are air-tightened using the cap. It is a product  

      made up of high-molecular materials so that the polymer-type lightning arrester does  

      not spatter when exploded. 


  ● LA for VITZRO TECH Power Distribution is developed into the most-wanted 18kV,  

      2.5kA using only our technology and passed KERI test to be adopted as the domestic  

      product. Also, this product is applied with the non-linear resistance of ZnO element. 


  ● It is designed and manufactured based on the accumulated experiences and actual
      test evaluation 

    - It is superior in preventing the moisture absorption since its air-tightening is excellent. 

    - It is light-weighted (2.4kg) when compared to the porcelain-type lightning arrester. 

    - It prevents secondary accidents (fragment scattering and etc.) when it explodes due to internal  

      temperature rise and expansion of arc resulting from the transient fault current. 

    - It is safe since the disconnector is a resistance-type. 

    - Creeping leakage distance is 645mm or more. 

    - It used an insulated rubber cover that does not allow the rain to penetrate to the upper terminal part. 

    - Applied Standard : IEC60099-4, IEEEStd C62-11 

1-2 SA (Surge Absorbers) 


   ● It is a surge absorber (SA) that is applied with the advanced insulating material,

      POLYSIL, and it is fully air-tightened into a mold structure. There is no drop of 

      residual voltage due to outside burning and it performs a perfect surge protection  

      without changing the characteristic even at the polluted area.


  ● Features 

    - It adopted POLYSIL full-molding that can be used outdoors. 

    - Based on the optimal design for outdoors, it is light-weighted. 

    - It is recognized for its quality since it passed IEC Test for the first time in the country. 

    - It ensures the stability by applying incombustible materials when there is a fault inside the distribution


    - Applied Standard : IEC60099-4, IEEEStd C62-11
