The conductivity is improved by the heat-resistant aluminum alloy lead on an outer layer, the T700 high-strength carbon fiber composite core with the density being 1.80g/cm<3> and the tensile strength being more than or equal to 4900MPa is adopted as the wire core to improve the tensile strength of a line, and realize a large-span transmission line with large capacity and the tower spacing being more than or equal to 3km; and the lead has light weight, small expansion coefficient and small sag, so that the sag of the lead is reduced.
Description
Technical field
The utility model relates to a kind of high-strength carbon fibre core heat-resistant aluminum alloy wire, belongs to power industry transmission line technical field.
Background technology
Employed lead is main with steel reinforced aluminium conductor basically in China's overhead transmission line at present; Its heat resistance, decay resistance and tensile strength relatively a little less than, so the transmission line capability of circuit, useful life receive certain restriction, aluminium alloy conductor is the renewal product of ordinary steel core aluminum stranded wire; Also be energy-conservation, material-saving, the product of save land (practicing thrift the transmission of electricity corridor); Adopt the core of carbon fiber complex core, further improved the tensile strength of lead as lead, thus span between the tower of the longer distance of realization; Especially cross over complex-terrains such as rivers, hills, have the advantage of highly significant.Yet in existing invention, novel patent or the disclosed document, the transportion wire road for the heat-resistant aluminum alloy wire realization >=3Km tower spacing that adopts the high-strength carbon fiber core is crossed over is not shown in report.
Summary of the invention
The purpose of the utility model is the problem that proposes to background technology, proposes a kind of high-strength carbon fibre core heat-resistant aluminum alloy wire, improves conductance with outer heat-resistant aluminum alloy wire, and employing density is 1.80g/cm
3, tensile strength>=4900MPa T700 type high-strength carbon fiber composite core increase circuit tensile strength as core, the big leap transportion wire road of realizing big capacity, tower spacing>=3km, lead in light weight, the coefficient of expansion is little, sag is little, has reduced the lead sag.
The technical scheme of the utility model is: a kind of high-strength carbon fibre core heat-resistant aluminum alloy wire, comprise high-strength carbon fiber composite core and heat resistant aluminum alloy wire, and it is characterized in that: the centre is that sectional area is 44.2～70.9mm
2The high-strength carbon fiber composite core, tensile strength>=4900MPa, density are 1.80g/cm
3, core coats heat resistant aluminum alloy wire all-in-one-piece overhead power transmission conducting wire outward, and conductor cross-section is 345.5～725.5mm
2Its beneficial effect is: owing to 150 ℃ of aluminium alloy conductor long-term work temperature, conductance >=60%IACS, working temperature and ampacity all are more than 2 times of ordinary steel core aluminum stranded wire, have improved the utilance of aluminium; The high-strength carbon fiber core is in light weight, the coefficient of expansion is little, sag reduces, can reduce the lead sag; Can realize >=tower of 3Km between span; Can realize the big leap stringing of complex-terrain, can reduce floor space again, alleviate the not enough problem of the nervous headroom in circuit corridor.
