Abstract

The subject of the invention is the method of producing self-rolling elongate element, in particular an electric cable and self-rolling elongate element, in particular an electric cable intended especially for power and signal transmission wires, ropes and cords. The essence of the method, according to the invention, consists in applying to the power transmission wires, the outer coating (1) of a polymer composite, consisting of a polymer and a material, which has magnetic properties in the amount of from 10% to 60% by weight and subsequently, the power transmission wire (2) with the applied outer layer (1) is being magnetized in the magnetic field, which lines are situated along the axis of element rolling, wherein the magnetic induction is equal to at least 2 Tesla. The element has the outer layer (1) contacting directly with the environment of the cable is made of polymer composite, consisting of a polymer and a material, which has magnetic properties in the amount of from 10% to 60% by weight, wherein the outer coating is magnetized along the axis of the element rolling.
