Abstract
The utility model relates to a middle-strength aluminum alloy conductor of an ultra-high-strength steel core, which comprises a steel core (1) and aluminum alloy single wires (2). The middle-strength aluminum alloy conductor of the ultra-high-strength steel core is characterized in that: the steel core (1) is obtained through twisting steel core single wires (3); and the aluminum alloy single wires (2) are twisted outside the steel core. According to the middle-strength aluminum alloy conductor of the ultra-high-strength steel core, the inner layer is made of ultra-high-strength steel core, and the outer layer is obtained through twisting the middle-strength aluminum alloy single wires with conductivity of 59%. Compared with the high-strength aluminum alloy conductor of the ultra-high-strength steel core, under a precondition that the cross sections are same, the middle-strength aluminum alloy conductor of the ultra-high-strength steel core is advantageous in that: the horizontal load and the vertical load are same; DC resistance at a temperature of 20 DEG C is reduced for 7%; when the environment temperature is 35 DEG C and the conductor temperature is 90 DEG C, capacity is improved for 3.1-3.3%; AC resistance loss is reduced for 7.5-8%; a reasonable structure is obtained; a smooth and compact surface is obtained; the conductivity exceeds 55% IACS; and the middle-strength aluminum alloy conductor of the ultra-high-strength steel core is more suitable for wide application on large-striding power transmission project than the high-strength aluminum alloy conductor of the ultra-high-strength steel core.
Description
Technical field
The utility model relates to lead, particularly strength aluminium alloy lead in a kind of extra-heavy steel core.
Background technology
Existing conventional wires is that power domain brings great convenience, and is widely used.At present, the current-carrying part of existing conventional wires adopts steel reinforced aluminium conductor, steel core be used for delivered current and aluminum steel for reducing corona and other losses.Along with Electricity Demand continues to increase, a kind of operating temperature height of grid power transmission field active demand, the novel transmission pressure of corrosion-resistant, big capacity replaces conventional wires, so aluminium alloy conductors steel occurred.Comprise steel core heat-resistant aluminum alloy wire, extra-heavy steel core high-strength aluminum alloy lead etc. in the aluminium alloy conductors steel, wherein steel core heat-resistant aluminum alloy wire long-term work temperature can reach 150oC and more than, and can make the stress of lead all concentrate on the steel core, make the lead core not be destroyed, the lead sag can not raise with temperature and strengthen, and ampacity is big; The extra-heavy steel core high-strength aluminum alloy lead of Chu Xianing had also obtained extensive use big the leap in the power transmission engineering afterwards.
Summary of the invention
For complying with aluminium alloy conductors steel in the development trend of power domain, the utility model provides strength aluminium alloy lead in a kind of extra-heavy steel core, and its internal layer adopts the strong steel core of extra-high-speed, and outer employing conductance is 59% stranded the forming of middle strength aluminium alloy single line.
For realizing above purpose, the technical solution adopted in the utility model is: strength aluminium alloy lead in a kind of extra-heavy steel core, and it comprises steel core (1) and aluminium alloy single line (2), it is characterized in that, described steel core (1) is by stranded the forming of steel core single line (3); Described aluminium alloy single line (2) is stranded in the outside (1) of steel core.
The material of described steel core single line (3) is the extra-heavy steel.
The material of described aluminium alloy single line (2) is middle strength aluminium alloy, and its conductance is 59%.
The beneficial effects of the utility model are: internal layer of the present utility model adopts the strong steel core of extra-high-speed, and outer employing conductance is 59% stranded the forming of middle strength aluminium alloy single line.With the strong steel core high-strength aluminum alloy of extra-high-speed lead at sectional area and aluminum steel when identical, have following advantage: horizontal loading, vertical load are identical; 20 ℃ of D.C. resistances descend 7%, 35 ℃ of ambient temperatures, and during 90 ℃ of conductor temperatures, ampacity increases by 3.1～3.3%; The AC resistance loss descends 7.5～8%; Rational in infrastructure, smooth surface is tight, and conductance surpasses 55%IACS; Be more suitable for being used widely big the leap in the power transmission engineering than extra-heavy steel core high-strength aluminum alloy lead.
