Superconducting copper tri-filar photoelectric composite cable

By placing the conductor and optical fiber separately in different rectangular jackets in the optoelectronic composite cable, and setting notches and color markings on the jackets, combined with an insulation layer, an aerogel layer, a vacuum insulation layer, and a liquid nitrogen circulation system, the problems of difficult separation of the conductor and optical fiber and overheating in optoelectronic composite cables are solved. This improves the ease of operation and heat dissipation, and ensures the safety and construction efficiency of the cable.

AI Technical Summary

Technical Problem

The existing optical fiber composite cable has a circular cross-section, which makes it difficult to separate and arrange the optical fiber and conductor. In addition, the small gaps inside the cable result in poor ventilation, which can easily lead to overheating of the conductor and may cause damage to the optical cable and economic losses.

Method used

Design a superconducting copper three-part four-wire optoelectronic composite cable, in which the conductor and optical fiber are respectively placed in different rectangular jackets and connected into a whole by a connector. The jacket is provided with notches and color markings to improve the ease of operation and heat dissipation. An insulation layer, an aerogel layer and a vacuum insulation layer are provided on the outside of the conductor to enhance the heat dissipation capacity. A liquid nitrogen circulation system is provided at the joint for cooling.

Benefits of technology

It enables convenient separation and connection of conductors and optical fibers, improves operational convenience and heat dissipation, prevents conductor overheating, reduces the risk of optical cable damage, and enhances cable safety and construction efficiency.
