Why Install Surge Arresters?
Surge arresters provide primary circuit protection to MV-HV cable and power systems against high voltage surges caused by atmospheric (lightning) and switching over voltages. Nexans medium and high voltage surge arresters protect substation switchgear (both air and SF6 gas insulated type), transformers, cables, overhead transmission lines and capacitors. Protection levels include 6.6kV, 11kV and 33kV (up to 42kV) – call to discuss your requirements.
