Abstract
Przewód energetyczny z rdzeniem kompozytowym otoczonym drutami charakteryzuje się tym, że ma rdzeń (1), który ma część wewnętrzną, zawierającą ułożone wzdłużnie lub splecione włókna 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 epoksydową utwardzaną termicznie, w ilości od 10% do 50% objętości gotowego rdzenia (1), i ma powłokę otaczającą część wewnętrzną i związaną z nią trwale, złożoną z żywicy epoksydowej utwardzanej termicznie, wypełnionej na przestrzeni całej objętości proszkiem ferromagnetycznym lub proszkiem magnetycznym, w ilości od 1 cm3 do 10 cm3, korzystnie 7 cm3 w każdym metrze gotowego rdzenia (1), a przy tym rdzeń (1) otoczony jest co najmniej jedną warstwą drutów z aluminium i/lub z aluminium wyżarzonego, korzystnie o przekroju okrągłym a najkorzystniej o przekroju trapezowym.A power cable with a composite core surrounded by wires is characterized in that it has a core (1) which has an internal part containing longitudinally arranged or intertwined armor fibers of one or more types of material, with a tensile strength of at least 1200 MPa, in an amount of 50% up to 90% of the volume of the finished core (1), permanently bonded to a thermally cured epoxy resin in an amount of 10% to 50% of the volume of the finished core (1), and has a coating surrounding and permanently bonded to the inner part consisting of a cured epoxy resin thermally, filled over the entire volume with ferromagnetic powder or magnetic powder, in an amount from 1 cm3 to 10 cm3, preferably 7 cm3 in each meter of the finished core (1), while the core (1) is surrounded by at least one layer of aluminum wires and / or annealed aluminum, preferably circular and most preferably trapezoidal.
