Aerospace cable

Abstract

The invention discloses an aerospace cable. The aerospace cable comprises a cable core, wherein the cable core comprises an I-shaped nylon framework, wire cores are placed on the left side and right side of the I-shaped nylon framework respectively, each wire core comprises a conductor, each conductor is covered with a foamed plastic insulating layer, a copper wire winding layer and an aluminum strip linkage armor layer in sequence, each conductor is also sleeved with an oval nylon framework, and the cable core is covered with a tensile belt, a plastic film, a zinc-coated steel wire braided shielding layer and an outer sheath in sequence. According to the aerospace cable, due to the fact that each conductor is sleeved with the corresponding oval nylon framework and the cable core is covered with the tensile belt, the plastic film and the zinc-coated steel wire braided shielding layer, the electrical characteristic, the mechanical characteristic, the high-temperature characteristic, the low-temperature characteristic, the low-friction characteristic, the chemical resistance, the weather resistance and the flame resistance are excellent.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an aerospace cable. Background technique [0002] When the existing cables receive mechanical vibration and bending deformation due to external force, the insulating layer and the sheath are prone to deformation, resulting in changes in the center distance of the conductors and affecting the electrical performance of the cable; in addition, they also have weather resistance, non-combustibility, The disadvantage that performance such as chemical resistance cannot be taken into account at the same time. [0003] In addition to excellent physical and mechanical properties and electrical insulation properties, wire and cable outer sheath materials also need to have good oil resistance, heat resistance, corrosion resistance and other properties. Traditional cable sheath materials are increasingly unable to meet harsh working environments. . Contents of the invention [0004] The pu...

[0003] In addition to excellent physical and mechanical properties and electrical insulation properties, wire and cable outer sheath materials also need to have good oil resistance, heat resistance, corrosion resistance and other properties. Traditional cable sheath materials are increasingly unable to meet harsh working environments.
