Retractable multi-group longitudinal water seal photoelectric composite cable and manufacture process thereof

Abstract

The invention provides a retractable multi-group longitudinal water seal photoelectric composite cable and a manufacture process thereof. Signal lines for transferring control signals, communication signals, optical signals and radio-frequency signals and power lines for transferring electric energy are compounded to form one cable, wherein the signal lines include multiple tightly-wrapped optical cables 1 and coaxial cables 4, the coaxial cables 4 are arranged among the multiple tightly-wrapped optical cables 1, and multiple shielding twisted pair cables 2 are arranged in the coaxial cables 4. Multiple tensile aramid fiber filling ropes 3 are arranged around the signal lines and a power line 5 and at the gap positions, water-stopping wrapping bands 6 with water-stopping bands are wound in layers among the multiple shielding twisted pair cables 2, water-stopping glue 7 is arranged at the positions of twisting gaps of metal conductors and cabling and twisting sub-gaps, and a sheathed reinforcing layer 8 and an outermost polyurethane sheath 9 are arranged outside the twisted and cabled composite cable. The retractable multi-group longitudinal water seal photoelectric composite cable has the advantages of being tension-resisting, abrasion-resisting, and capable of resisting 4.5MPa longitudinal water pressure and being used in retractable mode and has multiple functions, and the trouble that multiple installation and layout times of various cables is avoided.

Description

technical field [0001] The invention is a retractable multi-group longitudinal water-sealed photoelectric composite cable and its preparation process, which is suitable for occasions with longitudinal watertight requirements such as submarines, warships, river and sea ships, seabeds, offshore oil platforms, large-scale water conservancy facilities, and tunnels. Realize the transmission of photoelectric signals such as power, control, communication, data, graphics, and video. Background technique [0002] At present, cables are usually divided into different fields such as power cables, control cables, communication cables, coaxial radio frequency cables, and optical fiber cables in the industry. Installation brings certain difficulties to the construction and installation, and the photoelectric composite cables on the market are mostly simple photoelectric combinations, which do not have good retractable and tensile functions, nor do they have longitudinal water sealing perf...

AI Technical Summary

Problems solved by technology

[0002] At present, cables are usually divided into different fields such as power cables, control cables, communication cables, coaxial radio frequency cables, and optical fiber cables in the industry. Installation brings certain difficulties to the construction and installation, and the photoelectric composite cables on the market are mostly simple photoelectric combinations, which do not have good retractable and tensile functions, and do not have longitudinal water sealing performance.

However, some special industries in the market are in urgent need of such high-performance and multi-functional optical composite cables. In view of the difficulty in producing such optical composite cables, they mainly rely on imports at present.
