The different versions of the switchgear and transformer terminations are designed for operation voltage up to 550 kV. The terminations comply to the standards where dimensions and scope of supply are specified, i.e. IEC 60859 for the switchgear termination and EN 50299 for the transformer termination.
Upon request the terminations can be adapted to fit into existing housings not in compliance with these standards.
The termination is equipped with an epoxy resin insulator. Like the outdoor terminations, the same prefabricated stress cone made of silicone rubber is used. Also in this case the interior of the insulator is filled with silicone oil. The epoxy resin insulator is cast in one piece with an integrated insulating ring at the bottom. In this way it is possible to isolate the cable metal screen from earth. Thus, the overall size of the termination is compact allowing installation even in confined space.
