  • Insulated winding, together with process and semi-finished product for the production thereof
    Patent number: 5455392
    Abstract: The invention concerns an electrical winding with a conductor layer (14) which is sealed in an insulating layer (30) of polyethylene. The polyethylene has a degree of crosslinking of at least 60% and contains an anti-oxidant. The starting material used is a not yet crosslinked polyethylene to which a foaming agent is added so that, when heated to be crosslinked, during which it also melts, the polyethylene penetrates between the individual turns (20) in the conductor layer (14). The protective insulating layer (24) round the individual turns of the winding consists of a material which is stable at the crosslinking temperature.
