Cable

Abstract

The invention discloses a cable. The cable comprises cable cores, wherein each cable core comprises an aluminum conductor, a copper conductor and an inner insulator layer in sequence from inside to outside; the cable cores are externally wrapped by a metal protection layer; the metal protection layer is internally provided with a filler; the metal protection layer is externally wrapped by an outer insulator layer; the outer insulator layer is internally provided with sensing fibers. According to the cable, the metal protection layer can prevent animals, such as mice, from damaging the structure in the metal protection layer; besides, the copper conductor and the aluminum conductor are comprehensively used, so that the damage of insulation layers can be found in time and the fire resistance is high; through the setting of the outer insulator layer, the cable has the characteristics of high temperature resistance and safety; the cable is simple and reasonable in structure, convenient to use, heat-resistant, pressure-resistant and wide in applicability.

Description

Technical field [0001] The invention belongs to the field of metal materials, and specifically relates to a cable. Background technique [0002] Existing cables are generally all-copper or all-aluminum. Because copper cables have better oxidation resistance, welding performance and conductivity than aluminum, they are widely used in transmission cables with large currents. However, copper wires are more expensive than aluminum. It is expensive and high in density. It is replaced by aluminum wires under certain conditions of use. With the continuous development of technology, the use of cables becomes more complicated and diversified. Copper or aluminum wires are also somewhat inadequate in comprehensive use; in addition, Such cables are susceptible to being bitten by animals such as mice and ants, exposing the core conductors, causing problems such as short circuits in the cables. Summary of the invention [0003] (1) Technical problems to be solved [0004] In order to solve the ...
