Surge Protection

02B · Medium Voltage

Metal oxide (ZnO) surge arresters with polymer case desing up to 42kV for the protection of Medium Voltage Substations, Switchgears and Overhead Lines.

02B1 :: Outdoor surge arrester

They provide excellent TOV performance. Safe, non-shattering failure in the short circuit test by pre-failing to higher fault currents. High energy handling capability.

02B2 :: Indoor surge arrester

Applications for the indoor surge arresters include protection of air-spaced insulated medium voltage switchgear networks and equipment from lightning and switching surge related over-voltages in areas with relatively high iso-keraunic levels.

02B3 :: Screened Separable Surge Arresters

The screened gapless surge arrester are “T“-shaped products. They are designed for direct connection onto outer cone bushings in accordance with EN50180 or EN50181 with interface type “C” or for parallel connection mating to the rear entry of the RSTI base screened connector system designed for system voltage up to 41 kV.
