Nexans Euromold Bushings | MV HV Switchgear Transformers

Nexans Bushings

The correct selection and specification of Nexans Euromold connectors is dependent on the cable specification and the equipment bushing type. There are 6 bushing interfaces common to MV electrical equipment (A, B, C, D, E or F).

The MV-HV electrical equipment to which Nexans Euromold connectors are fitted to must have the correct bushing Interface and be designed to suit the cable specification.

Euromold connectors are suitable for connecting single and 3 core polymeric insulated cables with copper wire or tape screens up to 33kV – this has recently been increased to 72kV to cater for offshore wind farm cable terminations onto 66kV equipment.
