lightning arrester
Product Name Polymer Lightening Arrester
Purpose The polymer lightening arrester limits the overvoltage due to different types or surge and prevents voltage breakdown as well as protecting human lives and equipment from explosion.
Characteristic
Features of Polymer Lightening Arrester
  • Polymer lightening arrester has excellent protective insulation as it uses ZnO, which has a high limiting voltage
  • As this is a spindle type lightening arrester, it has adequate response characteristics. It also has guaranteed activity on surge that overlaps.
  • As it uses ZnO, which has a high current impulse withstand, it absorbs surge perfectly despite long-term usage.
  • As this is a Gapless type arrester using ZnO, it is maintenance free.
  • The structure of this lightening arrester is FRP filament winding, which leads to excellent pressure relief. This means that it is safe from accidents from explosion and scattering (polymer-type)The structure of this  is FRP filament winding, which leads to excellent pressure relief.

  • Because it’s made up of silicone, it has less danger of breaking due to external pressure. (polymer type)
  • It uses silicone, which is an excellent water repellent. This makes it suitable for use in damaged areas or outdoors. (polymer type)
