Abstract

The invention relates to the technical field of cables and provides a reinforced photoelectric composite cable. The reinforced photoelectric composite cable comprises single-strand cables, wherein each single-strand cable comprises at least 3 conductors (4), an insulating layer (6) wraps each conductor, a shielding layer (9) wraps at least two single-strand cables, filler (7) is arranged in gaps between the shielding layer (9) and the single-strand cables, an inner sheath layer (8) wraps the shielding layer (9), at least 3 optical fibers (1) are arranged inside the inner sheath layer (8), a water blocking layer (2) wraps each optical fiber (1), an outer sheath layer (5) wraps the inner sheath layer (8), and a metal wire layer (3) is evenly distributed between the inner sheath layer (8) and the outer sheath layer (5).

Description

technical field [0001] The invention relates to the technical field of cables and provides a reinforced photoelectric composite cable. Background technique [0002] The existing cables have a simple structure, most of them have poor shielding performance, and cannot meet the requirements of anti-magnetic field, anti-radio frequency, and anti-static, and there is no strengthening effect in the existing cables, and the cable's tensile capacity is weak, and the waterproof layer of the optical fiber of the existing photoelectric composite cable It is easy to be swollen by water, squeeze the optical fiber, and affect the transmission efficiency of the optical fiber. [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 p...
