Description

Technical Field

[0001] The utility model relates to the field of cable production, and more specifically to a wire feeding device of a tubular stranding machine for cable production. Background Art

[0002] Cable is made of one or more mutually insulated conductors and an outer insulating protective layer, which transmits electricity or information from one place to another. Some cables have long transportation distances and large current carrying capacity. In order to ensure that the cable has certain bending performance and is not damaged. The cables on the market are now made of multiple strands of wire cores. The stranded wire is achieved by twisting the single wire around the strand axis with equal angular velocity and the stranded wire moving forward at a uniform speed. There are two commonly used copper and aluminum wires. Copper and aluminum wires can be twisted into conductor cores of various cross-sections and different types of wires and cables. It is suitable for occasions with high operating frequencies and excessive skin effect and proximity effect losses of single-strand wires. The use of stranded wires can reduce the operating temperature. Compared with single-strand wires of the same cross-sectional area, stranded wires have higher mechanical properties and flexibility. In the past, stranding machines were usually only used for the production of cables of fixed specifications, which was very inconvenient.
