Abstract
The invention discloses a composite core carbon fiber electric heating cable and a preparation process. The cable comprises a conductive layer consisting of a composite core carbon fiber bundle, an insulating heat-conducting and temperature-resistant layer, an insulating water-proof and moisture-proof protective layer and an outer insulating sheath, and is characterized in that the composite core carbon fiber conductive layer is a composite material which is formed by mixing glass fibers in the carbon fiber bundle, compounding the compound carbon fiber bundle into a rope and finally curing the rope into a whole by a thermosetting resin, wherein the composite carbon fiber bundle passes through the centers of two aluminum wire layers to form an aluminum-based carbon fiber composite core; and the diameter of the composite core is 3.0 to 4.0mm. The composite core carbon fiber electric heating cable has the advantages of higher conductivity than that of a steel core cable, lower weight than that of the steel core cable, high tensile strength and simple production technology.
Description
Technical field the present invention relates to the electric heating field, is a kind of composite core carbon fiber electric heating cable and preparation technology concretely.
Background technology is 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, the weight of these leads is bigger, resistance is bigger, thereby cause transmission of electricity expense height, 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 are all at the novel overhead power transmission of research road lead, to replace traditional steel reinforced aluminium conductor, carbon fiber composite core wire arises at the historic moment thus.Have only the U.S. and Japan to develop this novel conductive wire at present in the world, they also reach tacit agreement: to the 3rd state output, Japan accounts for the world about 40 once the output of tame carbon fiber lead enterprise.China electric wire research institute, electrical building research institute and national grid Co., Ltd have all begun the experimental study work to the ACCC lead at present.
Summary of the invention the present invention promptly is at the deficiencies in the prior art, provide a kind of in light weight, thermal coefficient of expansion is little, intensity is high, capacity is big, the composite core carbon fiber electric heating cable of high temperature resistant, low degree of speeding, corrosion-resistant, low line loss characteristics.
For achieving the above object, the technology used in the present invention solution is: a kind of composite core carbon fiber electric heating cable comprises conductive layer, insulating heat-conductive heat-resistant layer, insulative water-proof moisture protection layer and outer layer insulation sheath by composite core carbon fiber Shu Zucheng.The electric conduction of carbon fiber layer coats the insulating heat-conductive heat-resistant layer outward, and the insulating heat-conductive heat-resistant layer coats insulative water-proof moisture protection layer outward, and the outer layer insulation sheath is coated on insulative water-proof moisture protection layer outside.
The preparation technology of a kind of composite core carbon fiber electric heating cable of the present invention, it is characterized in that said composite core carbon fiber conductive layer is that glass fiber is mixed in the carbon fiber bundle, again the compound carbon fiber bundle is combined into rope, be integral by thermosetting resin cured more at last, carbon fiber wire is that a kind of alloying element content that strengthens with high strength and high modulus carbon fiber mixing is: Mg 1-4%, Cu 1-4%, the aluminium of Mn 0.2-0.4% is matrix, carbon fiber is continuous, and the content of carbon fiber is the composite material of 20-50%.Composite material is made filament by pipe mold, sneaks into the compound bunchy of glass then, the carbon fiber reinforce plastic bundle is penetrated the center of two-layer aluminum steel again, forms the aluminum base carbon fiber composite core, and the diameter of composite core is 3.0-4.0mm.
Advantage of the present invention be the conductance of composite core carbon fiber cable than steel core cable height, weight ratio steel core cable is low, and tensile strength is big, production technology is simple.
