To achieve these goals, the technical solution of the utility model: a kind of high strength steel core high-strength aluminium-magnesium-slicon alloy twisted wire, by becoming with outer high-strength aluminium-magnesium-slicon alloy wire fabric as conductor as the internal layer High Strength Steel core group of reinforcement; Described internal layer High Strength Steel core group is by a zinc-plated steel core of circle and outer successively around the zinc-plated steel core group of the second layer that coats, the 3rd layer of zinc-plated steel core fabric one-tenth; Described outer high-strength aluminium-magnesium-slicon alloy wire group is outwards become around the 4th layer of aluminium-magnesium-slicon alloy wire group that coats, layer 5 aluminium-magnesium-slicon alloy wire group, layer 6 aluminium-magnesium-slicon alloy wire fabric successively by internal layer High Strength Steel core group; Wherein, the diameter of the aluminium-magnesium-slicon alloy wire in described the 4th layer of aluminium-magnesium-slicon alloy wire group, layer 5 aluminium-magnesium-slicon alloy wire group, the layer 6 aluminium-magnesium-slicon alloy wire group is 2～5mm.
The beneficial effects of the utility model: in Al-Mg-Si aluminium alloy, magnesium and silicon form hardening constituent Mg in aluminium
2Si, its solubility changes along with the increase of temperature, therefore can heat-treat.Carry out artificial aging after the aluminium-magnesium-slicon alloy wire cold working again, can significantly improve the ageing strengthening effect, electric conductivity also is improved thereupon simultaneously.Data show simultaneously, diameter is that the tensile strength of 2～5mm aluminium-magnesium-slicon alloy wire is 315～325MPa, the tensile strength of comparing hard-drawn aluminium wire of the same type is 160～180MPa, promoted tensile strength greatly, and ampacity is also improved accordingly, loss reduces, therefore, the high strength steel core high-strength aluminum alloy twisted wire that adopts aluminium-magnesium-slicon alloy wire to cooperate zinc-plated steel core to make has the intensity height, and is in light weight, corrosion-resistant, line loss is low, and creep-resistant property is good, than similar steel reinforced aluminium conductor, ampacity can improve 5%-8%, running wastage falls 5%, and economic benefit is obvious, guarantees that simultaneously the reliability that transmission line is powered under extreme natural environment closes fail safe, applicable to big leap, the overhead transmission line of heavy icing area and old transmission line capacity-increasing transformation etc.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is sectional view of the present utility model.
Embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of high strength steel core high-strength aluminium-magnesium-slicon alloy twisted wire as shown in Figure 1 is by becoming with outer high-strength aluminium-magnesium-slicon alloy wire fabric as conductor as the internal layer High Strength Steel core group of reinforcement;
Described internal layer High Strength Steel core group is by a zinc-plated steel core 1 of circle and outer constitute around the zinc-plated steel core group 2 of the second layer, the 3rd layer of zinc-plated steel core group 3 of coating successively;
Described outer high-strength aluminium-magnesium-slicon alloy wire group outwards is made of around the 4th layer of aluminium-magnesium-slicon alloy wire group 4, layer 5 aluminium-magnesium-slicon alloy wire group 5, the layer 6 aluminium-magnesium-slicon alloy wire group 6 that coat successively internal layer High Strength Steel core group;
Wherein, the diameter of the aluminium-magnesium-slicon alloy wire in described the 4th layer of aluminium-magnesium-slicon alloy wire group 4, layer 5 aluminium-magnesium-slicon alloy wire group 5, the layer 6 aluminium-magnesium-slicon alloy wire group 6 is 2～5mm.
The zinc-plated steel core group 2 of the second layer in the utility model, the 3rd layer of zinc-plated steel core group 3, the 4th layer of aluminium-magnesium-slicon alloy wire group 4, layer 5 aluminium-magnesium-slicon alloy wire group 5, layer 6 aluminium-magnesium-slicon alloy wire group 6 all are closely to be arranged into ring-type by zinc-plated steel core or aluminium-magnesium-slicon alloy wire by circle, and layer overlaps between the adjacent layer, global shape is cylindrical to meet the shape need of present most cable core.
Be compared as follows for the parameter between high-strength aluminium-magnesium-slicon alloy wire and the hard-drawn aluminium wire:
