Electric wire and cable for flexible composite drag links and manufacturing process thereof

Abstract

The invention belongs to the technical field of wire and cable, especially relating to wire and cable for a flexible composite towline and its manufacturing process, which comprises a conductor, cable materials and stuffing. The cable materials are set outside of the conductor and stuffing. The conductor is a copper conductor while the stuffing is polypropylene reticular tearing fiber. The said cable materials is the insulating compound and covering materials which is composed of polyvinyl chloride soft packing, butyronitrile compound and elastomer. The cable provided in the invention has the advantages of compact structure in reason with less space occupation, outstanding flexibility in continuous bending and low price. The successful development of the wire and cable for flexible composite towline supplies a gap in domestic production. Batch production of the cable not only creates a business opportunity for enterprises, but also drives the same trades to make batch production of the wire and cable for the flexible composite towline, which brings invaluable economic efficiency of enterprises and inestimable social benefit.

Description

technical field [0001] The invention belongs to the technical field of technical wires and cables, and in particular relates to a wire and cable for a flexible composite drag chain and a manufacturing process thereof. Background technique [0002] The premise of the research and development of wire and cable technology for flexible composite towlines can only be carried out when the market demand, personnel quality, manufacturing capacity, and production environment have reached the level of qualified products. [0003] The key technology of wire and cable for flexible composite drag chain is to solve the conductor stranding process, tooling, and new cable material extrusion process. At present, the conductors of existing wires and cables have the problems of easily broken strands and large pitches. Therefore, it is a new subject to be developed urgently to manufacture a process that meets the requirements of the cable and select qualified insulation and sheath materials to...

AI Technical Summary

Problems solved by technology

Therefore, it is a new subject to be developed urgently to manufacture a process that meets the requirements of the cable and select qualified insulation and sheath materials to ensure that the composite cable can continue to bend up to 500 million times, and the cable can still work normally. At present, there is no wire and cable standard for flexible composite drag chains in China to refer to
