Abstract
The invention discloses a heating cable, and relates to special equipment or methods for manufacturing conductors or cables. The problems of the twisting and the bending of a cable, the non-rounding condition and the instable forming degree of the extruded cable, the loosening of a cable core, the reduced tensile strength and the shape deformation of the cable, due to the turnover of a special-shaped insulating wire core after the adoption of an existing cable extruding machine and the addition of heating and filling materials containing EPDM rubber 40 nm in grain diameter, can be solved. Theheating cable comprises an outer protective layer, an armor layer, an inner protective layer, an insulating layer and a conductor layer, wherein the above layers are sequentially wrapped from outsideto inside. Four to six anti-shielding layers are distributed on the outer ring of the conductor layer. The anti-shielding layers are located between the conductor layer and the insulating layer. Heating and filing materials are filled between the conductor layer and the insulating layer. According to the technical scheme of the invention, the twisting and the bending of the cable, caused by the turnover of the special-shaped insulating wire core, can be avoided. The invention further discloses equipment for machining and extruding the heating cable.
Description
technical field [0001] The invention relates to special equipment or methods for manufacturing conductors or cables, in particular, a heating cable and its extrusion equipment. Background technique [0002] The main production process of power cables (power cord series) has the following steps: [0003] Commonly used copper and aluminum rods for wire and cable, at room temperature, use a wire drawing machine to pass through one or several die holes of the drawing die to reduce the cross section, increase the length and improve the strength. Wire drawing is the first process of each wire and cable company, and the main process parameter of wire drawing is mold matching technology. [0004] When the copper and aluminum monofilaments are heated to a certain temperature, the toughness of the monofilaments is improved and the strength of the monofilaments is reduced by means of recrystallization, so as to meet the requirements of electric wires and cables for conductive cores. ...
