Carbon fiber reinforced aluminum alloy conductor cable

Abstract

The invention relates to a carbon fiber reinforced aluminum alloy conductor cable which comprises wire cores consisting of aluminum alloy conductors and insulating layers extruded outside the aluminum alloy conductors, wherein more than two wire cores are twisted to form a cable core; an inner lining layer is wrapped outside the cable core; an interlocking armor layer is wrapped outside the inner lining layer; an outer sheath layer is extruded outside the armor layer; a carbon fiber reinforced core is arranged in a gap between the wire cores; an optical unit is arranged in a gap between the cable core and the inner lining layer, and comprises a plurality of optical fibers; and at least one optical fiber is a grating optical fiber inscribed with a temperature measurement grating. The cable has the benefits that the cable is high in strength, can better substitute for a copper conductor cable and solves the problems of easy oxidation, poor creep resistance and the like of an electrical pure aluminum conductor; communication is available; and the temperature of the cable can be monitored in real time.

Description

Technical field [0001] The invention belongs to the field of cables, in particular to a cable using a new type of aluminum alloy material and structure. Background technique [0002] In China in the 1950s and 1970s, copper was used as a strategic resource, and the national policy for electrical applications was "substituting aluminum for copper". Copper cables could not be used in civil buildings, and most of the cable conductors used were electrical pure aluminum conductors. ; By the mid-1980s, the problems in the use of aluminum conductor cables were exposed, especially the oxidation of aluminum conductor joints caused many fires. At that time, the price of copper and aluminum was not much different, and copper conductors were used in electrical, mechanical, and durable applications. The superiority in performance has gradually become copper-based in application; after the 1990s, a number of national standards and specifications also required the use of copper cables in civil ...

AI Technical Summary

Problems solved by technology

Since the existing electrical pure aluminum cables are prone to oxidation and corrosion, which can cause problems such as joint fires, it is necessary to study and apply a new type of aluminum conductor to solve such problems and improve the reliability of aluminum cables.

[0003] In addition, the existing cables have insufficient tensile strength and low tolerance to natural disasters such as freezing rain and snow; now there are photoelectric composite cables with optical fiber communication functions and power transmission functions, which can realize various control signals, network signals and power transmission functions. Transmission, to meet the needs of multi-network integration of telecommunication network, broadcasting network, Internet, power network

However, the temperature rise of this kind of photoelectric composite cable cannot be monitored during operation, and it is easy to cause the whole cable to be damaged due to the temperature rise caused by the increase of the power conductor load.
