Problems solved by technology

According to the different structures of ordinary cables and coaxial cables, it is not difficult to find that due to the addition of shielding and insulation layers, coaxial cables have higher requirements for the tensile strength of the inner conductor, especially in the case of long wiring distances. The tensile strength of the cable is not enough It is dangerous and can only be compensated by adding overhead equipment, which will significantly increase the cost of use

Abstract

The invention discloses an aluminum alloy for cables. The aluminum alloy is prepared from the following elements in percentages by weight: 0 to 0.10% of Si, 0.80% to 1.26% of Fe, 0.15% to 0.25% of Cu, 0 to 0.03% of Ti, 0 to 0.01% of impurity element monomers and 0 to 0.15% of impurity element summation and the balance of Al. The aluminum alloy disclosed by the invention is particularly applicable for inner conductors of coaxial cables, and the tensile strength of the aluminum alloy is higher than that of existing other aluminum alloys for cables, so that the problems that the tensile strength of an aluminum ally rod for copper-clad aluminum inner conductors of the coaxial cables at present is relatively low and the requirement cannot be met in some application occasions are solved.

Description

technical field [0001] The invention belongs to the field of cables, especially coaxial cables, and in particular relates to an aluminum alloy for cables and a preparation method and application thereof. Background technique [0002] Cables are used to transmit electric (magnetic) energy, information and wire products that realize electromagnetic energy conversion. According to the use, it can be divided into bare wire products, power cables, communication cables, optical fibers and winding wires. The materials used in cable products can be divided into conductive materials, insulating materials, filling materials and sheath materials according to their use parts and functions. Made of copper, aluminum, copper-clad steel, copper-clad aluminum and other non-ferrous metals with excellent electrical conductivity. [0003] Ordinary cables are usually rope-like cables twisted by several wires or groups of wires. Each group of wires is insulated from each other, and is often twi...
