Hybrid cable integrating electric power and data transmission
ActiveCN104835559AImprove crosslink strengthExcellent electromagnetic wave shielding performancePower cables including communication wiresPower cables with screens/conductive layersPolyesterCopper conductor
The invention discloses a hybrid cable integrating electric power and data transmission. The cable comprises two electric power copper conductors and two data copper conductors. The two data copper conductors are respectively wrapped by a shielding insulating layer. A single-sided aluminum foil layer wraps the outer surfaces of the two shielding insulating layers. A polyester tape layer wraps surfaces of the single-sided aluminum foil layer, an inner sheath layer, and a filling rope. A double-sided aluminum foil layer wraps the outer surface of the polyester tape layer. A flame-retardant layer wraps the outer surface of the double-sided aluminum foil layer. An outer sheath layer wraps the outer surface of the flame-retardant layer. The shielding insulating layer contains PVC resin, ethylene-vinyl acetate copolymer, isodecyl phthalic acid, polythiophene, siloxane, fumed silica, cerium oxide, antimonous oxide, and asbestos wool. The cable improves reflection and absorption of low-frequency electromagnetic waves, and has good physical and mechanical property of stretching and tearing strength while improving crosstalk and signal attenuation, and improves flame retardation performance.

The invention discloses an integrated data cable for a communication power source. The integrated data cable comprises an aluminum core, two electric power copper wires, two data copper wires and a herringboned frame; two data copper wires are respectively wrapped with a shielding insulated layer; and an insulating foamed layer, a single-sided aluminum foil layer and an inner sheath layer are respectively located in the first cavity, second cavity and third cavity of the herringboned frame. The shielding insulated layer is composed of the following components by weight: 100 parts of PVC resin; 40 to 60 parts of ethylene-vinyl acetate copolymer; 10 to 12 parts of isodecyl phthalate; 15 to 20 parts of polythiophene; 5 to 10 parts of siloxane; 20 to 25 parts of fumed silica; 0.5 to 1 part of cerium(III) oxide; and 5 to 10 parts of antimony(III) oxide. With the integrated data cable of the invention adopted, the reflection and absorption of low-frequency electromagnetic waves can be improved, the problem of crosstalk and signal attenuation can be solved, and the crosslinking strength of base materials is improved. The integrated data cable has better physical and mechanical properties such as high tensile and tearing strength.
