  • 6/10 (12kV)
  • 6.35/11 (12kV)
  • 8.7/15 (17.5kV)
  • 12/20 (24kV)
  • 12.7/22 (24kV)
  • 18/30 (36) kV
  • 19/33 (36) kV
  • 20.8/36 (42) kV

Euromold 400PB plug-in surge arrester can be used with Euromold 400TB and 440TB tee connectors  – all suitable for use with Interface C Symmetrical type bushings on SF6 gas-insulated switchgear.

This surge arrester is a metal oxide varistor surge arrester in an elbow configuration that is tested for AC withstand and partial discharge prior to leaving the factory.

Connector accessories include: dead-end receptacle, dead-end plug, stand-off plug and earthing plug for type C interfaces.

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.
