Abstract

The invention provides a power cable production device resistant to alternating working conditions. The device comprises a plurality of rotatable material racks and a winding device capable of rotating in multiple directions, wherein a container for accommodating lubricating materials is arranged under the material racks, the top of the container is provided with a plurality of wire inlets communicating with the hollow rotating shafts of the material racks, and a second porcelain tube for passing the strands is provided at the bottom of the container. By adopting the above scheme, a lubricating layer can be adhered to the surface of the raw material wires of the cable, that are, the oxygen-free copper wires, and the lubricating layer is a high-expansion graphite worm. By arranging the container in the stranding process, the stranding between the raw material wires can adsorb minute flake graphite between the raw material wires, which reduces the micro-friction between the oxygen-free copper wires in the power cable under alternating working conditions, greatly improves the service life of the power cable, and improves the trouble-free working time of the equipment.

Description

technical field [0001] The invention relates to the field of cable production equipment, in particular to a power cable production device resistant to alternating working conditions. Background technique [0002] Under alternating working conditions, the service life of the cable is not only related to the deformation capacity of the material itself, but also related to the micro-friction between the materials. In applications that require higher alternating speeds, the micro-friction between the cores causes greater wear and tear. Thus affecting the resistivity and electromagnetic shielding effect of the core. Chinese patent document CN105825915A describes a high-temperature-resistant flexible cable for automatic submerged arc welding machines. A thin layer of talc powder is provided in the cable, which can reduce micro-friction between wire cores and improve the service life of the cable under alternating working conditions. However, this solution is more difficult to pr...
