Problems solved by technology

[0002] With the rapid development of cable technology, the steel core cable core has been replaced by a higher strength non-metallic fiber composite core, which significantly reduces the weight and sagging of the cable, and improves the original steel core cable core. There are disadvantages such as large demand for metal and poor corrosion resistance, but this type of composite material core also has problems such as looseness, which is not conducive to curing, poor fatigue resistance, and easy fracture.

Abstract

The invention relates to the technical field of power cables, in particular to a carbon fiber cable core. The carbon fiber cable core comprise a conductor wire core layer, a conducting medium layer and an insulating layer, wherein the conducting medium layer is attached to the outside of the conducting wire core layer; and the insulating layer is coated outside the conducting medium layer. The carbon fiber cable core is characterized in that: the conducting wire core layer consists of carbon fibers and a bonding agent, wherein the bonding agent is prepared from the following components in parts by weight: 100 parts of bisphenol type A epoxy resin, 50-70 parts of curing agent, 1-3 parts of accelerant, 5-20 parts of ceramic fiber and 1-5 parts of organic silicon coupling agent. Due to the adoption of the carbon fiber cable core, the properties such as dead weight, tensile strength, bending resistance and the like of a cable are further improved, and the use requirements of a transmission cable on the aspects of hardness, corrosion resistance, safety coefficient and the like are met.
