Weather-proof cable for power and data transmission

Abstract

The invention discloses a weather-proof cable for power and data transmission, comprising two power copper conductors, two data copper conductors and a filler cord. Each power copper conductor is covered with an insulating layer; the insulating layers are disposed in parallel and placed in an B form; an inner sheath layer externally covers the surfaces of the insulating layers; a partition is located between the inner sheath layer and a single-side aluminum foil layer; two ends of the partition are provided with a first side tail part and a second side tail part; the partition is in a spiral structure in the lengthwise extension direction; a polyester tape layer covers the surfaces of the single-side aluminum foil layer, the inner sheath layer and the filler cord; a shielding insulating layer comprises, by weight, 100 parts of PVC (polyvinyl chloride) resin, 40 to 60 parts of ethylene-vinyl acetate copolymer, 10 to 12 parts of diisodecyl phthalate, and 15 to 20 parts of polythiophene.

Description

technical field [0001] The invention relates to an integrated data cable, in particular to a weather-resistant cable with 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 defini...

[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
