Description

Overview

EXLIM-T surge arresters are used for the protection of switchgear, transformers and other equipment in high voltage systems against atmospheric and switching overvoltages. For use when requirements of lightning intensity and energy capability are very high.

Application

The EXLIM-T surge arrester has been verified to meet Station class requirements of IEEE C62.11 (IEEE Standard for Metal-oxide surge arresters for AC power circuits) and line discharge class 5 requirements of IEC 60099-4 (IEC Standard for Metal-oxide surge arresters without gaps for AC systems).
