Problems solved by technology

However, after adding the anti-ultraviolet filling material of carbon black fiber with a particle size of 50nm, after using the wire drawing machine, it is easy to turn over the special-shaped insulated core and cause the twisting of the cable, and it is easy to appear out of roundness and formability of the cable after twisting. The instability of the cable core, the looseness of the cable core, the decrease of the tensile strength, and the deformation of the cable shape

Abstract

The invention discloses an anti-ultraviolet photovoltaic cable and relates to special equipment or method for manufacturing conductors or cables. The problems that according to existing stranding technologies, after an anti-ultraviolet filling material where carbon black fibers with the particle size of 50 nm are added and a wire drawing machine is used, special-shaped insulating wire cores are likely to turn over, accordingly cables are twisted, the cable cores become loose, the tensile strength is reduced, and the cables deform are solved. The cable comprises an outer protective layer, an armor layer, an inner protective layer, an insulating layer and a conductor layer which are sequentially wrapped from outside to inside, wherein four to six anti-shielding layers are distributed on theouter ring of the conductor layer, the shielding layers are located between the conductor layer and the insulating layer, the portion between the conductor layer and the insulating layer is further filled with an anti-ultraviolet filling material, and the outer protective layer uses an irradiation cross-linked polyolefin sheath. According to the technical scheme, the situation that the special-shaped insulating wire cores turn over and accordingly the cables are twisted is prevented. The invention further discloses stranding equipment for processing the anti-ultraviolet photovoltaic cable.

Description

technical field [0001] The invention relates to special equipment or methods for manufacturing conductors or cables, in particular, a UV-resistant photovoltaic cable and its twisting 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 co...
