A photoelectric composite cable with internal isolation strengthening

Abstract

The invention discloses an internal isolation enhanced photoelectric composite cable which comprises a sheath layer, an optical fiber unit aluminum tape protection layer, tight-buffered optical fiber units, a cable unit aluminum tape screening layer and twisted lead wire pairs, wherein the optical fiber unit aluminum tape protection layer and the cable unit aluminum tape screening layer are semi-round aluminum tape wrapping sleeves respectively; the tight-buffered optical fiber units are arranged in the optical fiber unit aluminum tape protection layer respectively; the twisted lead wire pairs are arranged in the cable unit aluminum tape screening layer respectively; a steel wire enhancement part is arranged in the middle of the internal isolation enhanced photoelectric composite cable. According to the internal isolation enhanced photoelectric composite cable disclosed by the invention, the twisted lead wire pairs and the tight-buffered optical fiber units are arranged in the symmetric aluminum tape wrapping sleeves respectively, compounded into a line and isolated from one another, the strength is enhanced, the production cost of power cables and optical cables is reduced, and the erection process is relatively simple and convenient.

Description

technical field [0001] The invention relates to the field of cable and optical cable design, in particular to a photoelectric composite cable with internal isolation and reinforcement. Background technique [0002] The wire and cable industry is the second largest industry in my country after the automobile industry. The total output value of wire and cable has surpassed that of the United States, becoming the world's largest wire and cable producer. [0003] With the continuous promotion of my country's communication network technology, the optical cable industry has developed rapidly, the number of new companies has continued to rise, and the overall technical level of the industry has been greatly improved. In some remote areas, the same bracket is used for the erection of cables and optical cables, which saves costs. However, in order to prevent the influence between cables and optical cables, cables and optical cables cannot use the same packaging line, and separate ded...

AI Technical Summary

Problems solved by technology

In some remote areas, cables and optical cables are erected using the same bracket, which saves costs, but in order to prevent the impact between cables and optical cables, cables and optical cables cannot use the same packaging line, and special lines need to be erected separately, which is costly. Increased wiring workload
