Carbon fiber reinforced self-temperature-measurement composite cable with aluminum alloy conductors

Abstract

The invention relates to a carbon fiber reinforced self-temperature-measurement composite cable with aluminum alloy conductors. An elastomer is arranged among a plurality of conductors coated with insulating layers, and the section of the elastomer is a quadrangle, four sides of which are concave to be cambered; a carbon fiber reinforced core is arranged at the inner side of the elastomer; a belting layer and a jacket layer coat the outer sides of the four conductors coated with the insulating layers in sequence, a plurality of through holes are annularly distributed on the inner edge of the jacket layer, and the sections of the through holes are elliptic; an optical unit is arranged in a gap between the conductors and the belting layer, and at least one optical fiber is a grating fiber marked with temperature-measuring grating. The carbon fiber reinforced self-temperature-measurement composite cable has the following beneficial effects that the carbon fiber reinforced self-temperature-measurement composite cable has larger intensity and can better replace a copper conductor cable; and communication and real-time cable temperature monitoring can be both realized.

Description

technical field [0001] The invention relates to cables, in particular to a carbon fiber reinforced aluminum alloy conductor self-temperature-measuring composite cable. Background technique [0002] Power cables with aluminum alloy conductors are mainly suitable for power transmission and distribution systems with a rated voltage of 35kV and below, for power transmission and distribution, and are widely used in electric power, construction, industrial and mining, metallurgy, petrochemical, transportation and other departments. When the demand for cables continues to increase today, copper resources are gradually being exhausted, copper prices continue to rise, and product use costs are relatively high. [0003] This kind of power cable is extruded by the outside during the process of processing and installation, which leads to the interaction between the insulating layers of the cable and is easy to be damaged, so that the conductors contact each other, thereby affecting the...

AI Technical Summary

Problems solved by technology

[0003] Due to the external extrusion of this kind of power cable during the process of processing and installation, the insulation layers of the cable interact and are easily damaged, making the conductors contact each other, thus affecting the information transmission of the cable.

[0004] 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.
