Photoelectric composite cable

Abstract

The invention relates to the field of cables and provides a photoelectric composite cable comprising at least two single-strand cables. Each single-strand cable comprises at least three conductors (4); each conductor is covered with an insulating layer (6); the single-strand cables are covered with a shield layer (9); filler (5) fills a gap between the shield layer (9) and the single-strand cables; the shield layer (9) is covered with an inner sheath layer (8); at least three fibers (1) are disposed within the inner sheath layer (8); the fibers (1) are covered with a waterproof layer (2); the inner sheath layer (8) is covered with an outer sheath layer (3).

Description

technical field [0001] The invention relates to the technical field of cables and provides a photoelectric composite cable. Background technique [0002] The existing cables have a simple structure, and most of them have poor shielding performance, which cannot meet the requirements of anti-magnetic field, anti-radio frequency, and anti-static, and there are no fusion optical cables for many cables. [0003] Since the world's first low-voltage power cable (rubber belt wrapped copper conductor) was produced in 1836, wire and cable have developed into a large product category with a wide range of uses and varieties. After more than 70 years of development, my country's wire and cable industry has also made great progress. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. At present, there are about 5,000 state-owned and above-scale enterp...
