Multifunctional electric power composite cable

Abstract

The invention discloses a multifunctional electric power composite cable. The cable comprises an aluminum core and two copper wires. The aluminum core is wrapped in a copper layer which is wrapped in an insulation layer. Each copper wire is wrapped in an insulation foaming layer equipped with multiple holes. The size of the holes is 50-70% of the size of the insulation foaming layer. The surfaces of the insulation layer and the insulation foaming layer are wrapped in a polyester belt layer. The polymer belt layer is wrapped in an aluminum foil layer. The outer surface of the aluminum foil layer is wrapped in an inflaming retarding layer. The size of the holes is 60% of the size of the insulation foaming layer. The aluminum foil layer is a double-faced aluminum foil layer. According to the invention, effects on the cable by high-frequency electromagnetic radiator and capacity coupling can be reduced; so the transmission performance of the cable is improved; and multiple cables like a coaxial cable and an electric power cable are integrated into one cable, so a phenomenon that the cables in a clutter is avoided.

Description

technical field [0001] The invention relates to a cable, in particular to a multipurpose power composite cable. Background technique [0002] Ordinary digital cable: Ordinary data transmission digital cable is generally a transmission wire made of electrical copper wire billet through drawing, annealing and other processes, and is coated with high-quality polyolefin to form a solid single wire; multiple solid single wires are combined with each other, according to a certain The twisted pitch is twisted to form a twisted pair wire; multiple twisted pair wires, according to the needs of integrated wiring, generally use 4 to 25 pairs of wires, and the total twisted wires are formed into a cable; finally, outside the cabled wire According to actual needs, generally, indoor cables are extruded with a layer of PVC polyvinyl chloride, and outdoor cables are extruded with a layer of PE polyethylene. [0003] With the rapid development of data communication and information technolog...

At the same time, there will be new electromagnetic interference sources in the surrounding environment. The higher the network operating frequency, the more serious the radiation, and the balance characteristics of UTP unshielded data cables are not enough to offset the electromagnetic radiation of the high-speed network itself and the electromagnetic radiation of the outside world. Interference (only able to meet the electromagnetic compatibility performance of 30~40MHz data transmission)

[0004] 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 Internet 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

[0005] Due to the limitations of the above-mentioned structure and wiring of the cables, the influence of electromagnetic radiation and capacitive coupling at high 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
