Heat-resisting type communication power source flexible cable

Abstract

The invention discloses a heat-resisting type communication power source flexible cable. The heat-resisting type communication power source flexible cable comprises two power copper wires and two data copper wires, wherein a separating plate is located between an inner sheath layer and a single-surface aluminum foil layer, a first lateral empennage part and a second lateral empennage part are arranged at the two ends of the separating plate respectively and located on the left and right sides of the separating plate respectively, and the separating plate is of a spiral structure in the length extending direction; the single-surface aluminum foil layer, the inner sheath layer and a filling rope surface are wrapped with a polyester belt layer; the outer surface of an inflaming retarding layer is wrapped with a shielding sheath layer, and the shielding sheath layer is composed of, by weight parts, PVC resin, ethylene-vinyl acetate copolymer, di-iso-decylphthalate, polythiophene, siloxane, cerium sesquioxide, antimonous oxide and asbestos wool. The electromagnetic wave shielding performance of a data cable is improved, the heat-resisting type communication power source flexible cable further has good tensioning and tearing strength physical mechanical performance, and the flame retardant property is further improved.

Description

technical field [0001] The invention relates to an integrated data cable, in particular to a heat-resistant communication power flexible cable. 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...

[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
