Hybrid cable integrating electric power and data transmission

Abstract

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.

Description

technical field [0001] The invention relates to a hybrid cable, in particular to a hybrid cable for integrated power and data transmission. Background technique [0002] In our existing integrated wiring system, generally use 4 pairs of ordinary digital cables for Internet access, data transmission, etc., use local telephone cables for wiring, telephone, voice transmission, etc., use ordinary coaxial cables for network TV, high-definition TV Watching, etc., when the above cables are wired, they need to be wired in the same pipeline to affect and interfere with each other. [0003] Due to the limitations of the above-mentioned structure and wiring of the cables, the influence of electromagnetic radiation and capacitive coupling at low frequencies becomes more and more prominent, which seriously affects the electrical performance of each cable, resulting in the comprehensive wiring of each cable to the home. The speed, the quality of telephone calls, and the definition of hig...

[0002] In our existing integrated wiring system, generally use 4 pairs of ordinary digital cables for Internet access, data transmission, etc., use local telephone cables for wiring, telephone, voice transmission, etc., use ordinary coaxial cables for network TV, high-definition TV Watching, etc., when the above cables are wired, they need to be wired in the same pipeline to affect and interfere with each other

[0003] Due to the limitations of the above-mentioned structure and wiring of the cables, the influence of electromagnetic radiation and capacitive coupling at low frequencies becomes more and more prominent, which seriously affects the electrical performance of each cable, resulting in the comprehensive wiring of each cable to the home. The speed, the quality of telephone calls, and the definition of high-definition images will all be affected to varying degrees, and since each cable is an independent unit, after years of heating and heating, it is easy to cause the sheaths of the cables to stick to each other, etc. , eventually lead to broken skin, even leakage, burning, and eventually a fire
