Water-blocking communication cable

Abstract

The invention discloses a water-blocking communication cable which comprises a cable core and a sheath, and is characterized in that the cable core consists of a twisted pair which is stranded by multiple pairs of insulation wire cores, a water-blocking filler is arranged in a gap of the twisted pair, the insulation cores are formed by lapping polyolefin insulation layers on a conductor, a composite aluminium-plastics tape is lapped on the twisted pair, the conductor is a copper clad aluminum solid core wire, a polyester tape taped covering is lapped on the outer surface of the cable core, and the polyolefin aluminum plastic sheath is wrapped outside the polyester tape taped covering. The water-blocking communication cable has the advantages of reasonable and simple structure, easy manufacturing, good transmission performance of a cable communication signal, and stable signal transmission; and two layers of polyester tapes are overlapped and lapped on the cable core, thus the heat-resistance quality of the cable is improved. The cable core is provided with the water-blocking filler, the aluminum plastic comprehensive sheath is adopted and is made of linear low density polyethylene, and thus the water-blocking communication cable can be water-blocking and damp-proof and is enhanced in the mechanical property.

Description

technical field [0001] The invention relates to a cable structure, in particular to a structure of a water-blocking 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 copper, it is necessary to find a material...
