Aging-resistant data cable for comprehensive wiring

Abstract

The invention discloses an aging-resistant data cable for comprehensive wiring. The aging-resistant data cable comprises an aluminum core and two data copper wires, wherein an insulation layer wraps each data copper wire, a shielding sheath layer wraps an outer surface of a flame-retardant layer, a partition plate is arranged between an insulation foaming layer and a single-sided aluminum foil layer, a first lateral tail wing part and a second lateral tail wing part are respectively arranged at two ends of the partition plate, the shielding sheath layer comprises the following constituents of 1,3-butadiene, styrene 5, an ethylene-vinyl acetate copolymer and chlorinated polyethylene, and the insulation layer comprises the following constituents: 60 parts of nitrile rubber, 40-50 parts of methyl vinyl silicone rubber, 25-35 parts of ethylene-vinyl acetate copolymer, 20-35 parts of chlorinated polyethylene and 10-12 parts of tetrabromophthalic anhydride. By the aging-resistant data cable, the reflection and the absorption of a low-frequency electromagnetic wave are improved, the crosstalk and the signal attenuation are improved, meanwhile, the crosslinking strength of a base material is also improved, and the aging-resistant data cable has relatively excellent stretching performance.

Description

technical field [0001] The invention relates to an access network cable, in particular to an anti-aging data cable for integrated wiring. Background technique [0002] In the existing integrated wiring system, 4 pairs of ordinary digital cables are generally used for Internet access and data transmission, local telephone cables are used for wiring, telephone and voice transmission, and ordinary coaxial cables are used for Internet TV and high-definition TV viewing, 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 de...

[0002] In the existing integrated wiring system, 4 pairs of ordinary digital cables are generally used for Internet access and data transmission, local telephone cables are used for wiring, telephone and voice transmission, and ordinary coaxial cables are used for Internet TV and high-definition TV viewing, 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
