Abstract

The invention provides a carbon fiber rod, a power cable and a manufacturing method of the carbon fiber rod, and relates to the technical field of power cables. The carbon fiber rod comprises a steel core special-shaped carbon rod; and the steel core special-shaped carbon rod comprises a dispersible steel wire rope and a plurality of bonded special-shaped carbon rods, the steel wire rope is arranged in the center of the plurality of special-shaped carbon rods and is stranded with the plurality of special-shaped carbon rods, the plurality of special-shaped carbon rods are tightly twisted in a circumferential manner, and the gap between the surfaces of the adjacent special-shaped carbon rods is zero, gaps between the plurality of special-shaped carbon rods and the steel wire rope are filled with an adhesive, and the outer layers of the plurality of special-shaped carbon rods are coated with insulating layers. In the prior art, a twisted composite reinforcing core is formed by twisting round carbon rods, a compression type strain clamp cannot be used, and if a resin pouring joint technology is adopted, the overall length is large. With the carbon fiber rod, the power cable and the manufacturing method of the carbon fiber rod adopted, the above technical problems can be solved.

Description

technical field

[0001] The invention relates to the technical field of power cables, in particular to a method for manufacturing a carbon fiber rod, a power cable and a carbon fiber rod. Background technique

[0002] With the continuous development of my country's modern industry, the total amount of energy demand is rapidly expanding, the energy layout and industrial distribution are seriously unbalanced, and the pollution of air, land and water sources in densely populated urban areas is becoming increasingly serious. Therefore, long-distance transmission of electric energy has always been an important task. important subject.

[0003] In recent years, some companies have developed reinforcement cores to replace the steel reinforcement cores used in traditional overhead aluminum stranded wires. They have significant advantages such as light weight, high strength, large transmission capacity, and low line loss, making them widely used in power transmission.
