Euromold 800SA

Medium & High Voltage Surge Arresters | MV HV

Euromold 800SA is a surge arrester (11kV-42kV) specified to protect MV-HV cables terminated into substations and connecting medium/high voltage cables in the following voltage classes:

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

Euromold 800SA surge arrester can be supplied with straight connector (450SR) or a tee connector (480TB, 484TB or 489TB)  or a coupling connector (800PB, 804PB or 809PB) – all suitable for use with Interface C Compact type bushings on SF6 gas-insulated switchgear.

Surge arrester designed to protect 12, 24, 36 and 42 kV class components, including transformers, equipment, cable and accessories from high voltage surges resulting from lightning or switching.

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

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