Background technology
Overhead power transmission conducting wire is that electric energy is held the carrier that is transported to receiving end from generating, and what generally adopted at present is the wire-core cable.This traditional wire-core cable by the round steel wire bar of (the Φ 6mm or the Φ 8mm) of certain diameter as heart yearn and many stranded the forming of aluminum steel, there is following deficiency: when cable exceeds the quata to decide design load (about 100 ℃), wire cored wire generates heat and extends, its expansion and contraction＞10～20%, sag of chain is big, and wire cored wire tensile strength is lower, and when serious ice and snow disaster occurring, cable is very easily broken; The reaction that produces electrolysis of wire cored wire energising back and aluminum steel or other parts, the influence use is received the order, and its line loss rate reaches 29%; The wire cored wire weatherability is poor, easily produces oxidation reaction layer, reduction of service life under solar ultraviolet radiation or rainwater etch.
Summary of the invention
Technical problem to be solved by this invention provides a kind of compound ultra-high strong aluminum conductor, and it not only has superelevation tensile strength, and the deadweight alleviate significantly, its line ampacity is greatly enhanced.
The technical solution adopted for the present invention to solve the technical problems is: compound ultra-high strong core aluminum conductor of the present invention is characterized in that: this aluminum conductor constitutes by a compound ultra-high strong heart yearn with along the stranded aluminum steel thereon of its length direction; Described compound ultra-high strong heart yearn comprises high-performance carbon fibre bundle, the high-strength basalt fibre bundle master core of longitudinal extension, shape twines continuously the high-strength S glass fiber bundle of main core in the shape of a spiral, and with high-performance carbon fibre bundle, high-strength basalt fibre bundle, high-strength S glass fiber bundle is fixed is the modified thermoplastic resin of one.
The invention has the beneficial effects as follows, increased substantially the tensile strength of heart yearn, the comprehensive breaking strength of lead is reached about 7700Mpa, sag of chain is little when built on stilts, and ice and snow disaster ability to bear strengthens significantly; Compare loss of weight about 75% with traditional wire cored wire, serviceability temperature can reach 250 ℃, under the long-pending condition of same cross-sectional, can improve 2.5 times of line ampacitys, and can reduce tower erection cost about 20%; Heart yearn is an insulator, can improve 30～40 years useful life of lead.
