Wear-resistant outdoor data cable

Abstract

The invention discloses a wear-resistant outdoor data cable which comprises an aluminum core, two data copper conductors and a filling rope, wherein a copper layer is coated with the aluminum core and an outer surface of the copper layer is coated with an insulation foam layer; each data copper conductor is coated with a shield insulation layer and outer surfaces of the two shield insulation layers are coated with a single-sided aluminum foil layer; a partition is positioned between the insulation foam layer and the single-sided aluminum foil layer, a first side tail fin part and a second side tail fin part are arranged at two ends of the partition respectively and positioned on a left side and a right side of the partition respectively, each shield insulation layer comprises specific components, the partition adopts a helical structure in a length extension direction, and the helical pitch of the partition is 75-90 mm; an outer surface of a flame-retardant layer is coated with an outer sheath layer. The wear-resistant outdoor data cable improves reflection and absorption of low-frequency electromagnetic waves, enhances the cross-linking strength of a basic material while improving crosstalk and signal attenuation, and has relatively high tensile and tear strength as well as physical and mechanical properties.

Description

technical field [0001] The invention relates to a composite cable, in particular to a wear-resistant outdoor data cable. 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 of Internet access, the quality of telephone calls, and the ...

[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 of Internet access, the quality of telephone calls, and the clarity 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., which will eventually lead to broken skin, even electric leakage, burning, and finally a fire
