Abstract

The invention discloses a communication cable which comprises a cable core, wherein the cable core is externally wrapped by a tape; the surface of the tape is wrapped by a shielding layer; the shielding layer is externally wrapped by a cable sheath; the cable core at least comprises a conductor and a conductor sheath; the conductor sheath is tightly wound around the conductor; an insulating layer is arranged between the conductor and the conductor sheath; the insulating layer is made of polyethylene; a heat preservation material is arranged on the surface of the shielding layer; the shielding layer is made of a metal material. By adopting the communication cable disclosed by the invention, the consumption of materials can be reduced, the cost can be lowered, the shielding effect can be improved, and a heat preservation function is achieved.

Description

technical field [0001] The invention relates to a communication cable. Background technique [0002] Communication cables are cables used to transmit telephone, fax, TV, data information and other signals. They are generally made of more than one pair of insulated wires hinged. Communication cables have the characteristics of large capacity, high transmission signal stability, and good confidentiality. . In the actual application process, the cable needs to be installed under harsh environmental conditions, so some cables will have an outer sheath aging during use, causing signal interruption during transmission and affecting people's work and life. Contents of the invention [0003] According to the problems existing in the prior art, the present invention discloses a communication cable, which includes a cable core, the outside of the cable core is wrapped with a tape, the surface of the tape is wrapped with a shielding layer, and the outside of the shielding layer is w...
