A smart solution for transformers

Transformer Connection System

For transformer connection systems the challenges are the dielectric design and the epoxy resin casting process. Thanks to our know-how in the field of production technology and materials these complex processing technologies are no issue for our team. We choose the suitable production technique and adapt the product to create the best solution.

Plug and Power – Completely Dry-Type

Prefabricated GIS Cable Termination

Prefabricated, dry-type cable terminations are state of the art in the field of GIS cable terminations. The GIS compartment is delivered with pre-installed socket, the plug is assembled on site. Our scope is the development of your termination as complete package, including the combination of stress cone and epoxy resin socket, the contact system as well as the required spring assembly and the cable gland.

Oil Filled or Dry-Type


To realize a smooth transition to an overhead line, we develop your outdoor termination according to your environmental requirements. With respect to the environment, oil insulated terminations cause significant issues. That’s why we developed a dry-type outdoor termination as a prefabricated accessory – Without the need of additional supporting insulators!
