Communication cable with low smoke, flame retardance and water resistance

Abstract

The invention discloses a communication cable with low smoke, flame retardance and water resistance, belonging to the technical field of cables. The communication cable comprises a cable core and a sheath. The communication cable is characterized in that the cable core is formed by double-twisted pairs twisted by a plurality of pairs of insulating wire cores; water-resistant fillers are arranged in gaps among the double-twisted pairs; each insulating wire core is formed by extruding a polyolefin insulating layer on each conductor; the double-twisted pairs are lapped with aluminium-plastic composite belts; the conductors are copper-clad aluminium solid core wires; the outer surface of the cable core is wrapped with a tin-plated copper wire weaving layer which is lapped with a polyester-belt lapping layer; and the polyester-belt lapping layer is externally extruded with the low-smoke and halogen-free polyolefin sheath. The communication cable disclosed by the invention has the advantages that the structure is reasonable and simple, the production and the manufacture are easy, the transmission performance of communication signals of the cable is good, and the signal transmission is stable; and the cable core is provided with the water-resistant fillers, the aluminium-plastic comprehensive sheath is adopted and is made of low-smoke and halogen-free polyolefin, so that not only are the flame retardance, the water resistance and the moisture resistance realized, but also the mechanical performance of the cable is enhanced.

Description

technical field [0001] The invention relates to a structure of a cable, in particular to a structure of a low-smoke, flame-retardant and water-resistant communication cable with good anti-interference performance, and belongs to the technical field of cables. Background technique [0002] In the field of communication, it is often necessary to use twisted pairs to transmit various electrical signals. Traditional communication cables are mainly composed of insulated cores and sheaths. The copper cores are all made of TR-type copper wires. Data communication cables are used in various intelligent buildings, In the integrated wiring market, there is a great demand, but at present, copper resources are in short supply, and copper prices are rising rapidly. The consumption of copper materials accounts for most of the cost of the entire communication cable, which brings huge cost pressure to the production of communication cables. In order to maximize the function of limited coppe...
