Problems solved by technology

[0002] Communication cables are usually placed on high wire racks. In winter, snow will accumulate more snow or even freeze on the cables. When the accumulated ice and snow reach a certain weight, the cables will be bent or damaged. The outer insulation of the communication cable may even cause the cable to be pulled off, resulting in interruption of the communication line; if artificial deicing is used, the deicing efficiency will be low due to the influence of the installation height of the communication cable; and the communication cable is easily damaged by woodpeckers or Parrot's peck, causing damage to communication cables

Abstract

The invention discloses an overhead communication cable which is convenient for deicing, which comprises a communication cable body, a heating assembly is installed on the outer surface of the communication cable body, and the heating assembly includes a first wire and a second wire arranged parallel to the communication cable body. Conductive wires, several electric heating wires arranged at equal intervals between the first conductive wire and the second conductive wire, and the two ends of the electric heating wires are respectively fixedly connected to the first conductive wire and the second conductive wire , the outer side of the heating assembly is sheathed with a sheath, the outer side of the sheath is fixed with an outer wire, and the outer wire is parallel to the communication cable body. The convenient deicing overhead communication cable adopts electric heating to deicing the communication cable, and has a good deicing effect, and can drive away birds pecking at the communication cable through low-voltage electric shock, thereby ensuring the safety of the communication cable.

Description

technical field [0001] The invention relates to the technical field of communication cables, in particular to an overhead communication cable which is convenient for deicing. Background technique [0002] Communication cables are usually placed on wire racks with a high height. When it snows in winter, more snow will accumulate on the cables, or even freeze. When the accumulated ice and snow reach a certain weight, the cables will be bent, and at least they will be damaged. The outer insulation of the communication cable may even cause the cable to be pulled off, resulting in interruption of the communication line; if artificial deicing is used, the deicing efficiency will be low due to the influence of the installation height of the communication cable; and the communication cable is easily damaged by woodpeckers or Parrot pecks, causing damage to communication cables. Contents of the invention [0003] The technical problem to be solved by the present invention is to ov...
