Problems solved by technology

However, the currently commercially available high-temperature and cold-resistant cables are mainly silicone rubber cables. The cable material has certain high-temperature and cold-resistant properties, but it is easy to break after a period of use. Chinese invention patent CN201310044263 discloses a carbon fiber composite cable Wire, the cable material has good high temperature resistance, but in extreme cold conditions, the degree of shrinkage is relatively large, and it is prone to breakage

Abstract

The invention belongs to the technical field of cables and discloses a cable for electric transmission lines. The cable is composed of a cable conductor and insulating materials wrapping the cable conductor. The invention further discloses application of the cable for the electric transmission lines. The cable for the electric transmission lines is good in cold resistance and high temperature resistance, and application region is wide; influences of extreme temperature conditions on the cable is small, tensile strength, fracture parameters, hardness and other performance parameters are not changed obviously.

Description

[0001] technical field [0002] The invention belongs to the field of electric wires and cables, and in particular relates to a cable used for power transmission lines and its application. [0003] Background technique [0004] A cable is usually made of one or more mutually insulated conductors covered with insulation and protective layers. It is a wire that transmits power or information from one place to another, and is widely used in power systems. There are many types of cables, currently widely used mainly include: XLPE insulated power cables, rubber-sheathed flexible cables, resistance cables for coal mines, marine cables, aluminum stranded wires and steel-cored aluminum stranded wires, PVC insulated Control cables, PVC insulated wires, submersible pump cables, elevator cables, railway signal cables, computer-specific cables, etc. [0005] The section of the power system from the outlet of the step-down distribution substation to the user end is called the transmiss...
