Rare earth aluminum alloy cable core and preparation method of cable

Abstract

The invention is applicable to the field of cables, and provides a rare earth aluminum alloy cable core and a preparation method of a cable thereof, the rare earth aluminum alloy cable core comprises a rare earth aluminum alloy cable core and a protective layer, a cable for transmitting data signals in the cable core comprises a central cable and inner layer cables uniformly distributed along the circumferential direction of the central cable, the central cable is tightly connected with the outer surface of the inner-layer cable, and the outer layer of the inner-layer cable is coated with a shielding layer. When the cable is manufactured, gaps among a plurality of cables are filled with the quick-dry pasty filler, the outlet of the cavity is in a regular shape, and the redundant filler on the surface of the cable is scraped off, so that each layer of the cable can be kept in a regular shape, and when a cable core of the cable is finally packaged, the outermost protective layer presents a regular and smooth shape, and the cable core of the cable is not damaged. Therefore, the appearance quality of the cable is ensured.

Description

technical field [0001] The invention belongs to the field of cables, and in particular relates to a rare earth aluminum alloy cable core and a preparation method of the cable. Background technique [0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating layer that transmits power or information from one place to another. It is usually a rope-like cable twisted by several or groups of wires (at least two in each group), each group of wires is insulated from each other, and is often twisted around a center, and the entire outer surface is covered with a high degree of insulation overlay. The cable has the characteristics of internal electrification and external insulation. [0003] In the existing cables, in order to ensure the stability of multiple groups of wires inside and prevent the entire cable from being deformed, fillers are usually placed inside the cables. The fillers are mostly ropes, rubber, rubber strips, etc., but the...

Problems solved by technology

[0003] In the existing cables, in order to ensure the stability of multiple groups of wires inside and prevent the entire cable from being deformed, fillers are usually placed inside the cables. The fillers are mostly ropes, rubber, rubber strips, etc., but these fillers also have a certain shape The thickness and thickness cannot completely fill the gaps between the multiple wires in the cable. Therefore, when the cable is made, the shape of the cable cannot be kept round, and there will always be bumps or depressions on the surface of the cable. The overall appearance quality cannot Guaranteed
