Abstract

The invention discloses a novel computer cold-resistant cable, and the cable comprises a cable core, wherein the cable core is formed by the intertwisting of four pair-twisted insulating wire cores. Each pair-twisted insulating wire core consists of a pair of stranded conductors located at the center, a stranded wrapping belt and a split-phase copper wire braided shielding layer, wherein the stranded wrapping belt and the split-phase copper wire braided shielding layer sequentially wrap the stranded conductors. A gap of the cable core is provided with a heating belt in an extruded manner, and the cable core is wrapped by a rock wool thermal insulation layer. The exterior of the rock wool thermal insulation layer is wrapped by a rubber and plastic inner sheath in an extruded manner. The exterior of the rubber and plastic inner sheath is provided with a steel wire layer in a braided manner, and the exterior of the steel wire layer is wrapped by a carbon screw thread outer sheath in an extruded manner. The cable is good in conductivity, and is strong in tensile capability. The outer sheath is not liable to crack, and the service life is long.

Description

technical field [0001] The invention relates to the field of cables, in particular to a novel computer cold-resistant cable. Background technique [0002] At present, as a kind of communication cable for transmitting signals, computer cables have made outstanding contributions to the development of my country's communication industry. With the development of industry, the coverage area of ​​communication signals is getting wider and wider. The armor layer of ordinary tensile cables is wound with steel wires, which increases the total weight of the cables. Some communication cables with large specifications and lengths are laid in an environment with a large height drop, and they are often damaged or even broken due to the weight of the cable. Cause communication signal transmission to be interrupted, resulting in irreparable economic losses. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, provide a new ...
