Description
技术领域 technical field
本实用新型涉一种高强碳纤维芯耐热铝合金导线，属电力行业输电线路技术领域。 The utility model relates to a heat-resistant aluminum alloy wire with a high-strength carbon fiber core, which belongs to the technical field of power transmission lines in the electric power industry.
背景技术 Background technique
目前我国架空输电线路中所使用的导线基本上以钢芯铝绞线为主，其耐热性能、耐腐蚀性能及抗拉强度相对较弱，因此线路的输电容量、使用寿命受到一定的限制，铝合金导线是普通钢芯铝绞线的更新换代产品，也是节能、节材、节地(节约输电走廊)的产品，采用碳纤维复合芯作为导线的线芯，进一步提高了导线的抗拉强度，从而实现更长距离的塔间跨距，尤其是跨越江河、丘陵等复杂地形，具有非常显著的优势。然而现有发明、新型专利或公开的文献中，对于采用高强度碳纤维芯的耐热铝合金导线实现≥3Km塔间距跨越的输送电线路，未见于报道。 At present, the conductors used in my country's overhead transmission lines are basically steel-cored aluminum stranded wires, and their heat resistance, corrosion resistance and tensile strength are relatively weak, so the transmission capacity and service life of the lines are limited to a certain extent. Aluminum alloy wire is a replacement product of ordinary steel-cored aluminum stranded wire. It is also a product that saves energy, materials, and land (saving transmission corridors). The carbon fiber composite core is used as the wire core of the wire to further improve the tensile strength of the wire. In order to achieve a longer span between towers, especially across complex terrain such as rivers and hills, it has very significant advantages. However, in existing inventions, new patents or published documents, there is no report on transmission lines that use heat-resistant aluminum alloy conductors with high-strength carbon fiber cores to achieve tower spacing ≥ 3Km.
发明内容 Contents of the invention

The outer heat-resistant aluminum alloy wire improves the conductivity, and the density is 1.80g/cm 3 , and the tensile strength is ≥ 4900MPa. The T700 high-strength carbon fiber composite core is used as the core to increase the tensile strength of the line, and realize a large-span transmission line with a large capacity and a tower spacing ≥ 3km. The weight of the wire is light, the expansion coefficient is small, and the sag is small, reducing the sag .

Composite core, tensile strength ≥ 4900MPa, density 1.80g/cm 3 , the wire core is covered with a heat-resistant aluminum alloy wire to form an overhead power transmission conductor, and the conductor cross-section is 345.5-725.5mm 2 . Its beneficial effects are: due to the long-term working temperature of aluminum alloy wire at 150°C and conductivity ≥ 60% IACS, the working temperature and carrying capacity are more than twice that of ordinary steel-cored aluminum stranded wire, which improves the utilization rate of aluminum; high-strength carbon fiber The core is light in weight, small in expansion coefficient, reduced in sag, can reduce conductor sag, and can achieve a span between towers of ≥ 3Km, which can not only realize large-span wiring in complex terrain, but also reduce the occupied area and ease the burden on the line. The problem of insufficient headroom in tight corridors.
