Abstract
The invention relates to a carbon fiber composite core type aerial insulation cable. The carbon fiber composite core type aerial insulation cable is characterized in that: the cable takes a carbon fiber composite core at the center as a bearing wire core, the carbon fiber composite core is externally stranded by a soft aluminum single wire, the soft aluminum single wire is externally wrapped in a shielding layer, the shielding layer is externally wrapped in an insulation layer, the fiber composite core takes carbon fiber filament as a main material, and the carbon fiber filament in strands is stranded, is then dipped in resin and then is solidified by employing a baking oven to form the carbon fiber composite core. The carbon fiber composite core type aerial insulation cable is advantaged in that the carbon fiber composite core type aerial insulation cable has all advantages of a carbon fiber composite core cable, has an insulation protection effect, can be widely applied to old and new lines; the carbon fiber which is dipped in the resin and is solidified through the baking oven has soft texture, so the cable prepared by the processed carbon fiber has better soft performance and smaller bending radius and can better serve in a transmission line compared with a traditional carbon fiber cable.
Description
Technical field
The present invention relates to electric wire field, relate in particular to a kind of carbon fiber complex core type aerial insulated cable.
Background technology
Development along with China's economic construction, the continuous growth of electricity needs, cable is also increasing as the demand of the carrier of delivery of electrical energy, and mostly the cable conductor of current domestic use is steel reinforced aluminium conductor and aluminium alloy conductors steel, the weight of these wires is larger, resistance is larger, thereby cause transmission of electricity expense high, and operating temperature is lower, can not adapt to the operation under hot conditions, therefore electric power transfer becomes " bottleneck " of electric power industry development, and various countries are all at research novel overhead power transmission road wire, to replace traditional steel reinforced aluminium conductor.
Carbon fiber complex core cable is compared and is had the following advantages with traditional steel-core-aluminium strand cable:
(1) lightweight: the density of carbon fiber complex core be the density of steel be 1/4.Therefore, the shaft tower span of aerial cable can increase, and reduces tower bar number and is about 16% left and right, reduces floor space simultaneously.
(2) intensity is high, and Fracture Force is large.The hot strength of carbon fiber complex core cable is about 2399MPa, is 1.97 times of ordinary steel wire, is 1.17 times of high strength steel.
(3) conductance is high, and ampacity is large.Aluminum steel sectional area in same diameter carbon fiber complex core cable is 1.29 times of conventional steel-core-aluminium strand cable, and ampacity improves 29% left and right.
(4) line loss is little.Carbon fibre composite is a kind of nonmagnetic substance, when wire can not produce magnetic hysteresis loss and eddy current loss during by alternating current, presents less AC resistance.
(5) corrosion-resistant, long service life.Carbon fiber composite core rod has been avoided steel core electrochemical corrosion between aluminum steel and zinc-coated wire when energising, makes long-term use of aluminum conductor and ageing-resistant.
(6) coefficient of linear expansion is little, and sag is little.
But carbon fiber cable core flexibility of the prior art is bad, bending radius is large, and the cable bend performance of making is bad.
Summary of the invention
Technical problem to be solved by this invention is the defect that overcomes steel reinforced aluminium conductor cable in prior art, and overcomes the defect that in prior art, carbon fiber cable core flexibility is bad, bending radius is large, and a kind of carbon fiber complex core type aerial insulated cable is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of carbon fiber complex core type aerial insulated cable, it is characterized in that, described cable is usingd carbon fiber complex core as carrying core, stranded soft aluminium type single line outside described carbon fiber complex core at center, at described soft aluminium type single line outer cladding screen, at described screen outer cladding insulating barrier; It is main material that described carbon fiber complex core adopts carbon fiber wire, after the carbon fiber wire that becomes thigh is stranded, adopts resin-dipping, then adopts curing oven to form.
Further, the thickness of described screen is 0.6mm, and the thickness of described insulating barrier is 3.4mm.
The invention has the beneficial effects as follows: have all advantages of carbon fiber complex core cable, and have insulation protection effect, can be widely used in the old and new's circuit, can be applied to electric pressure is the low-voltage circuits such as 1kv, 10kv; Through resin-dipping and adopt the carbon fiber wire after curing oven, quality is soft, and the cable of making is better than traditional carbon fibres cable flexibility, has less bending radius, can better serve transmission line.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
