Abstract
The utility model relates to an aluminum twisted line, in particular to a steel core trapezoid-section soft aluminum twisted line, which comprises a steel twisted line. A soft aluminum bow-shaped line layer is wrapped outside the steel twisted line. The steel core trapezoid-section soft aluminum twisted line is simple in structure, light, high in strength, capable of resisting high temperature and corrosion, low in line loss and high in conductive rate.
Description
Technical field
The utility model patent relates to a kind of aluminium stranded conductor, relates in particular to the soft aluminium stranded conductor in a kind of steel core trapezoid cross section.
Background technology
Along with the develop rapidly of power industry, overhead transmission line conductor is had higher requirement in the present prior art, the conductive performance of traditional steel reinforced aluminium conductor is poor, and the progress of science and technology forces scientific and technical personnel to develop the various novel conductive wires to satisfy the demands.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the prior art, provides a kind of simple in structure, and
The soft aluminium stranded conductor in steel core trapezoid cross section that result of use is outstanding.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The soft aluminium stranded conductor in a kind of steel core trapezoid cross section comprises steel strand wire, and described steel strand wire are coated with soft aluminium bow molded lines layer.
The tensile strength of annealed aluminum wire is 1/2 of hard-drawn aluminium wire, and elongation is greater than 10 times of hard-drawn aluminium wire; The conductance of annealed aluminum wire than hard-drawn aluminium wire high 2%.
Annealed aluminum wire has the very low and very big characteristic of elongation of yield strength; Therefore when the working temperature of twisted wire arrives the migration point temperature; The mechanical load that twisted wire bears all " transfer " is given steel core, also promptly bears whole tension force by steel core, and working temperature then depends on the softening temperature of steel core.Steel reinforced soft aluminum strand has made full use of the natural characteristic and the design feature of material, can bring up to 270 ℃ and not obvious reduction tensile strength to serviceability temperature.
As preferably, described steel strand wire are coated with the soft aluminium bow molded lines layer of two layers of mutual superposition.
Therefore, the soft aluminium stranded conductor in a kind of steel core trapezoid cross section of the utility model, simple in structure, in light weight, intensity is big, and is high temperature resistant, corrosion-resistant, and line loss is low, and conductance is high.
Description of drawings
Fig. 1 is the sectional structure sketch map of the utility model.
