Description
Technical field
The utility model composite material core strengthens transmission cable and belongs to the electric power transfer field of materials, relates to a kind of thermosetting resin carbon fibre composite core transmission cable.
Background technology
Along with the continuous development of China's economic construction, the continuous growth of electricity needs, cable is also increasing as the demand of the carrier of electric energy transmitting; And mostly the cable conductor of present domestic usefulness is steel reinforced aluminium conductor and aluminium alloy conductors steel, and the weight of these leads is bigger, and resistance is bigger; Thereby cause the transmission of electricity expense high; And operating temperature is lower, can not adapt to the operation under hot conditions, so electric power transfer becomes " bottleneck " of electric power industry development; Various countries all use lead on the novel overhead power transmission of research road, to replace traditional steel reinforced aluminium conductor.
Carbon fiber cable is compared with traditional steel core aluminium strand cable and is had the following advantages:
1, intensity is 2 times of plain conductor.The tensile strength of ordinary steel wire is 1240Mpa-1410Mpa, and the carbon fiber of ACCC lead mixes the curing plug, is the former twice.
2, conductance is high, and energy-conservation 6%.Since magnetic loss and thermal effect that carbon fiber cable does not exist wire material to cause, and under the condition of carrying same load, have lower operating temperature, can reduce transmission loss about 6%.
3. low arc drop reduces sag more than 2 times.Carbon fiber cable is compared with steel core aluminium strand cable has significant low sag characteristic, and sag can effectively reduce the insulating space corridor of overhead wire less than 1/2 of steel reinforced aluminium conductor under hot conditions, has improved the fail safe and the reliability of lead operation.
4. 10-20% in light weight.The proportion of carbon fiber composite core wire is about 1/4 of steel, and under identical external diameter, the aluminium sectional area of ACCC is 1.29 times of conventional steel core aluminium strand cable.The carbon fiber cable unit weight has shown the lightweight advantage of carbon fiber cable than the light 10-20% of conventional steel core aluminium strand cable.
5, corrosion-resistant, be higher than 2 times of plain conductor useful life.Carbon fibre composite and environment are affine, have avoided conductor couple corrosion problem between aluminum steel and the galvanized steel wire when energising simultaneously, delay the aging of lead effectively, are higher than 2 times of plain conductor useful life.
6, same capacity track investment cost is lower than plain conductor.Because the operation of carbon fiber cable times capacity, and characteristics such as tensile strength is high, sag is little, in light weight, the span between bar, the tower is increased, highly reduce, the capacity line cost is lower than plain conductor equally.
The utility model content
The utility model purpose is exactly to above-mentioned deficiency, proposes a kind of both good conductivity, in light weight, again the cable of the also higher composite material core enhancing of intensity.
The thermosetting resin carbon fibre composite core transmission cable of the utility model is characterized in that the power transmission cable skin is that the aluminum steel of multilayer conductive, center contain many mixed carbon fibre aluminum matrix composite cores; The diameter of cable is 16-40mm, around one group of composite material core, is provided with the multilayer aluminium stranded conductor, and the quantity of composite material core is 7～19, and aluminum steel is 1～3 layer on every side.
Further, composite material core number is 7 in the cable; The outer number of plies is one deck, and the aluminum steel number is 12, aluminum steel diameter 3.2mm; The outside diameter of cable is 16mm.Cable weight is 411.6kg/km.
The utility model has overcome the conduction rate variance of original cable, transmission lag, not corrosion resistant shortcoming; Have corrosion-resistant, the anti-hysteresis, thermal coefficient of expansion is little, high conductivity, the beneficial effect of light weight.
