Abstract
The utility model relates to a novel big crossing structure sky cable conductor for the transmission line especially relates to a special high strength steel core aluminium alloy stranded conductor (JLHA1G6A -500400 -6061). By 61 ghents high strength galvanized steel wires as strengthening the core, to have two -layer conductivity be the 52.5%IACS high strength aluminum alloy stranded conductor to spiral winding on strengthening the core, high strength aluminum alloy stranded conductor inlayer is provided with 27 52.5%IACS high strength aluminum alloy stranded conductors, high strength aluminum alloy stranded conductor skin is provided with the spiral winding opposite direction of 33 52.5%IACS high strength aluminum alloy stranded conductors, adjacent two -layer high strength aluminum alloy line. The enhancement core divide to adopt special high strength steel line G6A. The high strength aluminum alloy stranded conductor adopt high strength aldray line. Special high strength steel core aluminium alloy stranded conductor's aluminum steel cross -section than being 1.24.
Description
Technical field
The utility model relates to a kind of novel Great span overhead transmission line cable, particularly relate to a kind of Extra High Strength steel core aluminium alloy stranded conductor (JLHA1/G6A-500/400-60/61).
Background technology
Cable is widely used in transmission line of electricity, especially aerial high-voltage power transmission line.For the cable for Great span aerial high-voltage power transmission line, do not require nothing more than its transmission capacity meeting circuit, simultaneously need to wire has and bigger draws anharmonic ratio, meet the sag requirement of span line.Existing frequently-used steel core aluminum alloy stranded wire can meet general large cross line, but cannot meet and cross over the large cross line that distance is bigger.
Summary of the invention
The purpose of this utility model is the Extra High Strength steel core aluminium alloy stranded conductor providing for above-mentioned weak point and meeting line requirements.
In order to achieve the above object, this utility model have employed techniques below scheme realize:
Extra High Strength steel core aluminium alloy stranded conductor by 61 Gents High Strength Steel line (G6A) as strengthening core, on strengthening core, spiral winding has two-layer conductivity to be 52.5%IACS high-strength aluminum alloy twisted wire, high-strength aluminum alloy twisted wire internal layer is provided with 27 52.5%IACS high-strength aluminum alloy twisted wires, high-strength aluminum alloy twisted wire outer layer is provided with 33 52.5%IACS high-strength aluminum alloy twisted wires, and the spiral winding of adjacent two layers high-strength aluminum alloy line is in opposite direction.
Described strengthening core 1 part uses Extra High Strength steel wire G6A.
Described high-strength aluminum alloy twisted wire uses high-strength aluminium-magnesium-slicon alloy wire.
The aluminum steel cross section ratio of described Extra High Strength steel core aluminium alloy stranded conductor is 1.24.
The extra-high steel core aluminum alloy stranded wire of this utility model (JLHA1/G6A-500/400-60/61) has 60 52.5%IACS high-strength aluminum alloy twisted wires, high-strength aluminum alloy twisted wire uses high-strength aluminium-magnesium-slicon alloy wire, structure is that internal layer is provided with 27, outer layer is provided with 33, different from the structure of conventional large-span conductors aluminium alloy, aluminum steel cross section ratio is 1.24, and domestic large-span conductors still belongs to the first.Secondly, Extra High Strength steel core G6A mechanical performance is higher than the highest standard of current domestic overhead stranded conductor galvanized strand wires so that the overall stretching resistance of wire is improved, and meets and crosses over apart from big large cross line requirement.
