Embodiment Construction

[0031] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0032] Such as Figure 1 to Figure 4 As shown, a communication cable according to the present invention includes an outer sheath tube; the outer sheath tube 1 is made of the following raw materials:

[0033] 85-90 parts by weight of polyolefin; 5-8 parts by weight of glass fiber; 6-10 parts by weight of clay; 3-4 parts by weight of plant ash; 2-3 parts by weight of acetyl tri-n-butyl citrate; 2-4 parts by weight of gum ; 0.6-1 parts by weight of silane coupling agent; 1.5-2 parts by weight of stearic acid; 0.7-0.9 parts by weight of white carbon black; 4-5 parts by weight of electrolytic zinc acid leaching residue;

[0034] The polyolefin is ethylene-1-octene copolymer; the gum is gum arabic;

[0035] The preparation method of the outer sheath p...

Abstract

The invention belongs to the technical field of power equipment, and particularly relates to a communication cable which comprises a wire core, an insulating layer, a thin film layer and an outer sheath pipe. The insulating layer is in a circular tube shape, and uniformly arranged bearing plates are fixedly connected on the surface of the insulating layer; uniform bubbles are distributed in the bearing plates. Inert gas is uniformly filled into the bearing plates at intervals in the extrusion molding process of the bearing plates so that the bubbles filled with the inert gas are formed; the wire core formed by a plurality of communication wires is wrapped in the cavity of the insulating layer; the thin film layer uniformly covers the surface of the insulating layer; the thin film layer ismade of PET or fluororesin and has a thickness of 4 [mu] m or more. The surface of the thin film layer is designed to be rough; the filler is filled between the thin film layer and the outer sheath pipe. The cooling cavity is arranged in the outer sheath pipe to isolate the external temperature from the interior so that the problem that the service life of the cable is shortened due to acceleratedaging of the internal insulating layer, the wire core and the like caused by high temperature influence is avoided.

Description

technical field [0001] The invention belongs to the technical field of power equipment, in particular to a communication cable. Background technique [0002] Through-wire cables are cables for the transmission of telephone, telegraph, fax documents, television and radio programmes, data and other electrical signals. It consists of more than one pair of mutually insulated wires twisted together. Compared with overhead open wires, communication cables have the characteristics of large communication capacity, high transmission stability, and good confidentiality. With the development of science and technology, the use environment of communication cables is becoming more and more diverse. In a high-temperature environment, it can only produce a flame-retardant effect, but cannot effectively isolate the impact of high temperature on the interior, so that the cable will accelerate aging in a high-temperature environment, or even be directly damaged. [0003] A through-wire cable...
