Problems solved by technology

This method is simple, but has limitations. Excessive twist will cause the carbon fibers to shear each other during stretching, resulting in loss of fiber strength.

Abstract

The invention discloses a carbon fiber reinforced polymer cable core with high elongation and a production method thereof. The carbon fiber reinforced polymer cable core structure is characterized by comprising a glass fiber insulating layer which is internally provided with a 2D (2-dimension) woven carbon fiber layer. The 2D woven carbon fiber layer is in a rope structure which comprises axial yarns and textile yarns. The axial yarns are made of aramid fibers, and the textile yarns are made of carbon fibers. The inner side of the 2D woven carbon fiber layer is provided with a high-strength glass fiber layer or an aramid fiber layer. The carbon fiber reinforced polymer cable core keeps the advantages of high carrying capacity, high working temperature, resistance to corrosion, light weight, high strength, low relaxation degrees and low loss of existing ACCC (aluminum conductor composite core) cable cores. However the elongation is increased and toughness of the cable core is improved, so that production and application of the cables are facilitated.

Description

technical field [0001] The invention relates to a carbon fiber composite cable core material structure with high elongation and a manufacturing method thereof. Background technique [0002] It is the current development direction of high voltage cables to replace the traditional steel core reinforced aluminum cables (ACSR) with carbon fiber composite core reinforced aluminum cables (ACCC). Compared with ACSR cables of the same diameter, ACCC cables can provide double the ampacity. It has low sag characteristics: the arc sag is less than 1 / 2 of the steel core aluminum stranded wire under high temperature conditions, which can prevent arcing, make the ground creatures safer, and can also reduce the height of the cable rack. The working temperature can reach up to 200~230℃. Good corrosion resistance: There is no potential corrosion between double metals. Delay cable aging, the service life is twice as long as that of ordinary cables. Light weight: The specific gravity of th...
