Abstract

A carbon fiber compound core of a power transmission circuit comprises an inner core body and an outer core body. The outer core body wraps the periphery of the inner core body, wherein the inner core body is carbon fibers prepared by carbonizing polyacrylonitrile fibers, the outer core body is high-strength glass fibers or basalt fibers, the inner core body and the outer core body are fixed and formed by heating cured resin, the cured resin is high-temperature-resistant special pultrusion epoxy resin prepared by adding modified anhydride compounds, the carbon fiber inner core body is of a straight-line type, and the high-strength glass fibers or basaltic fibers are of a twist increasing bundling type. The strength of a compound wire produced by the carbon fiber compound core is twice higher than the strength of an existing wire of the same type, the electric conductivity is higher, magnetic loss and heat loss are not generated, energy can be saved by more than 6%, the sag is lower due to the fact that the weight of the wire is reduced by 10-20%, and the compound core further has the advantages of being wearproof and long in service life.

Description

technical field [0001] The invention relates to a core wire bearing the weight of a cable between two iron towers in a power transmission line, in particular to a composite material core wire, in particular to a carbon fiber composite core of a power transmission line. Background technique [0002] Since 1800, there have been few major innovations in the wires used for overhead power transmission. Among them, steel-cored aluminum wires have been used the most, as the steel strands that bear the weight of overhead power transmission cables. Magnetic loss and thermal effects cause line loss in the output line. In addition, the tensile strength of the steel strand is not high enough to bear the weight of ice and snow, and it is easy to cause the tower to collapse in bad weather. With the development of the power industry, the requirements for transmission wires are getting higher and higher, and a new type of composite material composite wire, namely carbon fiber core aluminum ...
