Lightning Arresters Polymer Type LA Type Rated voltage Applied circuit voltage Nominal discharge current Discharge withstand current rating (4×10㎲) Rated frequency VITZROEM polymer type LA is a 18kV-5kA product that is used in KEPCO distribution lines and general high-voltage customers. To prevent explosion by hygroscopic deterioration, which accounts for most accidents in existing porcelain type LAs, winding by FRP insulation material was conducted on the ZnO element and internal components, the interface between FRP insulation material and polymer rubber housing was treated, and both ends...

Lightning Arresters Porcelain Type LA Type Rated voltage Applied circuit voltage Nominal discharge current Discharge withstand current rating (4×10㎲) Rated frequency 18kV, 2.5kA VITZROEM 18kV/2.5kA LA for distribution line was developed by our proprietary technology, and selected by KEPCO after passing the tests of KEPCO and KERI. It also has the following features according to the excellent non-linear resistance characteristic of ZnO element. Ideal steep response characteristic by gapless type Small and light-weight (80% of gap type in size) High reliability ensured by the simplification...

Surge Absorbers Surge Absorbers VITZROEM SA is manufactured with an advanced insulation material polysil, in the nation’s first mold structure ensuring perfect tightness. It shows no decrease of discharge voltage by external damage, and protects against surges without characteristic changes even in a polluted area ● Completely molded polysil for outdoor use Light-weight due to its optimal external design Passed KERI test for the first time in the country Stability ensured due to non-combustible material in case of accidents in the switch cabinet Rating of the surge absorber Type Rated...
