NEW: Dry-type, pluggable high voltage surge arresters

The new HV-CONNEX dry-type pluggable surge arrester for 145 kV voltage level offers various benefits compared to conventional surge arresters




Due to its insulation and field control made from solid silicone, no liquids or insulating gases relevant for the environment are present. This makes installation and operation particularly easy because it does not require regulations for pressure vessels to be followed and gas monitoring is therefore not necessary. The solid insulation also allows for enormous space savings when installing the surge arrester which is easy to remove or replace.

  • Solid insulation and field control made from silicone
  • No costly oil and gas work
  • Contact-safe design of transformer and GIS
  • Easy connection and pretestability of transformer and GIS with utilization of the full CONNEX system
