Abstract
The invention discloses an aluminum core wire carbon fiber transmission cable which comprises a central aluminum wire. Three carbon fiber heating wires are twisted outside the central aluminum wire. Three carbon fiber heating wires are arranged in the shape of a Chinese character 'pin'. The carbon fiber heating wires are coated with a heat dissipating layer. A silicon rubber insulation layer is arranged outside the heat dissipating layer. According to the invention, due to the fact that the structure is adopted, the tensile strength of the twisted wire is improved, and the tensile strength can reach 1800Mpa and is improved by 9 to 10% compared with the tensile strength of the carbon fiber reinforcement core in the prior art; due to the fact that the tensile strength is improved, the cable's ability to resist different kinds of wind, rainstorm and other different kinds of harsh environments is greatly improved; the overhead span is increased about 10%; the cable can meet the erection demands of wide rivers and mountain areas; and due to the fact that the tensile strength is improved, the overhead tension is decreased and the height of an erection bar is reduced, and the combination greatly reduces the erection cost.
Description
Technical field
The present invention relates to a kind of carbon fiber cable, especially a kind of aluminum core line carbon fiber power transmission cable.
Background technology
Electric power is carried at a distance, and overground part adopts steel reinforced aluminium conductor usually, the underground mining insulated cable of extruded insulation layer outside.Steel reinforced aluminium conductor, if adopt ordinary steel wire, its twisted wire tensile strength is only the 1240Mpa left and right, as adopted high-tensile steel wires, also only reaches the 1410Mpa left and right.Built on stilts lay span and be restricted, and built on stilts degree of speeding is large, not only cause that to set up cost high, and opposing external force ability, meet unexpected external force as strong wind, heavy rain, the broken string accident easily occurs.Thereby the existing steel reinforced aluminium conductor tensile strength of generally using is low, has become the electric power transfer bottleneck.
Summary of the invention
The invention provides a kind of aluminum core line carbon fiber power transmission cable, good bandability, tensile strength is larger, and temperature tolerance is good, has reduced production cost, has improved useful life.
For addressing the above problem, the present invention adopts following technical scheme: a kind of aluminum core line carbon fiber power transmission cable, comprise the center aluminum conductor, outer stranded three carbon fiber heating lines that have of its center aluminum conductor, three carbon fiber heating lines are isosceles triangle and arrange, carbon fiber heating line is wrapped with heat dissipating layer, and heat dissipating layer is outside equipped with silicone rubber insulation layer.
Optimize, above-mentioned aluminum core line carbon fiber power transmission cable, its carbon fiber heating line comprises some carbon fiber lines and some glass fibers, the stranded connection of carbon fiber line and glass fiber, be provided with resin fillers between carbon fiber line and glass fiber.
Optimize, above-mentioned aluminum core line carbon fiber power transmission cable, be provided with the anti-folding silk of toughness in its silicone rubber insulation layer, be provided with soft tension silk in heat dissipating layer.
Type of the present invention, owing to adopting said structure, has not only improved the tensile strength of twisted wire, and its tensile strength can reach 1800 Mpa, can strengthen core raising 9-10% by more above-mentioned prior art carbon fiber; The raising of tensile strength, greatly improved the ability of the various adverse circumstances such as the anti-various strong wind of cable, heavy rain, and can make built on stilts span increase by 10% left and right, can meet broad river, set up in Ji Da mountain area, river, and tensile strength improves, also make built on stilts degree of speeding reduce, can reduce the hack lever height, both combinations, the larger reduction set up cost.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below with best embodiment, the present invention is described in detail
.
As shown in Figure 1, the present invention is a kind of aluminum core line carbon fiber power transmission cable, comprise center aluminum conductor 1, outer stranded three carbon fiber heating lines 2 that have of its center aluminum conductor 1, three carbon fiber heating lines 2 are isosceles triangle and arrange, carbon fiber heating line 2 is wrapped with heat dissipating layer 3, and heat dissipating layer 3 is outside equipped with silicone rubber insulation layer 4.Carbon fiber heating line 2 comprises some carbon fiber lines 21 and some glass fibers 22, and carbon fiber line 21 and the stranded connection of glass fiber 22, be provided with resin fillers 23 between carbon fiber line 21 and glass fiber 22.Be provided with the anti-folding silk 41 of toughness in silicone rubber insulation layer 4, be provided with soft tension silk 31 in heat dissipating layer 3.Type of the present invention, owing to adopting said structure, has not only improved the tensile strength of twisted wire, and its tensile strength can reach 1800 Mpa, can strengthen core raising 9-10% by more above-mentioned prior art carbon fiber; The raising of tensile strength, greatly improved the ability of the various adverse circumstances such as the anti-various strong wind of cable, heavy rain, and can make built on stilts span increase by 10% left and right, can meet broad river, set up in Ji Da mountain area, river, and tensile strength improves, also make built on stilts degree of speeding reduce, can reduce the hack lever height, both combinations, the larger reduction set up cost.
Finally it should be noted that: obviously, above-described embodiment is only for example of the present invention clearly is described, and is not the restriction to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And the apparent variation of being amplified out thus or change are still among protection scope of the present invention.
