Abstract
The invention provides a high-strength aerial cable, comprising a conductor, and an insulating layer. The conductor is made of high-strength aluminium alloy. The aluminium alloy conductor is in a cylindrical shape. A complex fiber core comprises carbon fiber filaments and fiber glass filaments. An insulating film wraps outside the conductor, and then the complex fiber core is winded on the periphery of the conductor, and finally, a protective coating is extruded on the periphery of the complex fiber core and the conductor. The protective coating is made of duplex-polyvinyl chloride. First, proper amount of Cr, Cu, and Mg is added in the aluminium alloy, solution strength of the aluminium alloy is increased, so strength of the aluminium alloy, especially tensile strength of the aluminium alloy are substantially improved. In addition, on the periphery of the conductor is the complex fiber core, so tensile strength of the cable is greatly increased. Moreover, the outermost layer uses the duplex-polyvinyl chloride, so tensile strength of the cable is enhanced to a certain extent.
Description
Technical field
The present invention relates to technical field of electric wires and cables, relate in particular to a kind of carbon fiber heating water-proof cable.
Background technology
Carry at a distance in the application at electric power, generally speaking, aerial part adopts steel reinforced aluminium conductor usually, and under ground portion adopts the insulated cable of outer extruded insulation layer.In the prior art, adopt steel reinforced aluminium conductor, rather than ordinary steel wire, because the tensile strength of ordinary steel wire is smaller, just be that high-tensile steel wires do not reach long pulling force apart from setting up between the cable yet.In addition, built on stilts span is restricted, and built on stilts yardstick is large, not only causes cost to raise, and opposing external wind and the ability of rainy day are relatively poor, if run into thunderstorm gale weather, and hail is freezing, easily fracture and cause accident.Therefore, providing a kind of aerial cable with higher-strength is those skilled in the art's urgent problems.
Summary of the invention
In order to solve the problems of above-mentioned existence, the present invention aims to provide a kind of high-intensity aerial cable.
The invention provides a kind of high strength aerial cable, comprise conductor and insulating barrier, described conductor is that high-strength aluminum alloy is made, affiliated aluminium alloy conductor is cylindric, and diameter is 2mm-6mm, and the alloying element of affiliated aluminium alloy according to mass fraction percentage is, Cr0.2-0.8%, Cu0.1-1.5%, Mg0.15-0.45%, all the other are Al; Also comprise composite fiber core, described composite fiber core comprises carbon fiber wire and glass fiber, metalling Cu on the described carbon fiber wire, and immersion plating Cu on the described glass fiber is shaped into rope then with the two mixing, and by phenolic resin curing; Then described conductor outer wrapping one deck dielectric film is wrapped in described composite fiber core the periphery of described conductor; Periphery at described composite fiber core and conductor extrudes one deck overcoat at last, and affiliated overcoat is duplex-polyvinyl chloride.
Further, described conductor is according to mass fraction percentage, and its component is Cr0.3-0.6%, Cu0.2-1.3%, Mg0.25-0.40%.
Further, described conductor also comprises rare earth element ce, and its content is 0.02-0.08%.
Further, the diameter of described composite fiber core is 0.2mm-1.0mm.
The invention provides a kind of high strength aerial cable, comprise conductor and insulating barrier, described conductor is that high-strength aluminum alloy is made, affiliated aluminium alloy conductor is cylindric, and diameter is 2mm-6mm, and the alloying element of affiliated aluminium alloy according to mass fraction percentage is, Cr0.2-0.8%, Cu0.1-1.5%, Mg0.15-0.45%, all the other are Al; Also comprise composite fiber core, described composite fiber core comprises carbon fiber wire and glass fiber, metalling Cu on the described carbon fiber wire, and immersion plating Cu on the described glass fiber is shaped into rope then with the two mixing, and by phenolic resin curing; Then described conductor outer wrapping one deck dielectric film is wrapped in described composite fiber core the periphery of described conductor; Periphery at described composite fiber core and conductor extrudes one deck overcoat at last, and affiliated overcoat is duplex-polyvinyl chloride.
Based on technique scheme, at first, added an amount of Cr in the aluminium alloy, Cu and Mg have increased the solution strengthening of aluminium alloy, so that the band of the intensity of aluminium alloy, particularly tensile strength promotes significantly; In addition, what be wrapped in the conductor periphery is composite fiber core, has greatly increased tensile strength and the toughness of cable; Moreover duplex-polyvinyl chloride that outermost layer uses has also been strengthened the tensile strength of cable to a certain extent.
