Abstract

Rdzeń kompozytowy przewodu energetycznego charakteryzuje się tym, że zawiera ułożone wzdłużnie lub splecione włókna (1a) zbrojące z co najmniej jednego rodzaju materiału, o wytrzymałości na rozciąganie przynajmniej 1200 MPa, w ilości od 50% do 90% objętości gotowego rdzenia (1), połączone trwale z żywicą (1b) epoksydową utwardzaną termicznie, w ilości od 10% do 50% objętości gotowego rdzenia, wypełnioną na przestrzeni całej objętości proszkiem (1c) ferromagnetycznym lub proszkiem (1c) magnetycznym, w ilości od 1 cm3 do 10 cm3, korzystnie 7 cm3 w każdym metrze gotowego rdzenia.The composite core of the power cable is characterized in that it contains longitudinally arranged or intertwined reinforcing fibers (1a) of at least one type of material, with a tensile strength of at least 1200 MPa, in an amount from 50% to 90% of the volume of the finished core (1), combined permanently with a thermally cured epoxy resin (1b) in an amount of 10% to 50% of the volume of the finished core, filled over the entire volume with ferromagnetic powder (1c) or magnetic powder (1c), in an amount of 1 cm3 to 10 cm3, preferably 7 cm3 in each meter of the finished core.
