Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific embodiments.

[0022] A high-temperature-resistant carbon fiber core photoelectric composite overhead wire includes a wire core, an optical fiber layer, a tightening tie 7, an insulating sheath-8, a heat-resistant layer 9 and an outer sheath 10 from the inside to the outside.

[0023] Among them, the wire cores are carbon fiber core 1, round aluminum wire 2 and insulating sheath 2 3 sequentially from inside to outside.

[0024] The carbon fiber core 1 is made of carbon fiber filaments as the central layer, and the outer layer is longitudinally wrapped with glass fiber filaments, impregnated with resin, and produced by a pultrusion process through a rod-making mold.

[0025] As a preferred embodiment of the present invention, the carbon fiber core 1 uses carbon fiber filament TR50S-12L as the central layer, and the outer layer is longitudinally wrapped with glass fiber roving EDR17-1200-38...

Abstract

The invention relates to a high-temperature-resistant carbon-fiber-core photoelectric composite overhead conductor, belonging to the technical field of conductors. The high-temperature-resistant carbon-fiber-core photoelectric composite overhead conductor sequentially comprises a wire core, an optical fiber layer, a tightening belt, a first insulating sheath, a heat-resistant layer and an outer sheath from inside to outside, wherein the wire core sequentially comprises a carbon fiber core, a round aluminum wire and a second insulating sheath from inside to outside; the optical fiber layer comprises a single-mode optical fiber unit and a multi-mode optical fiber unit; the single-mode optical fiber unit and the multimode optical fiber unit are symmetrically arranged at two sides of the wirecore; and two layers of trapezoidal soft aluminum molded lines are symmetrically arranged between the single-mode optical fiber unit and the multimode optical fiber unit. The high-temperature-resistant carbon-fiber-core photoelectric composite overhead conductor is used for improving the comprehensive performance of the composite conductor.

Description

technical field [0001] The invention belongs to the technical field of wires, and in particular relates to a high-temperature-resistant carbon fiber core photoelectric composite overhead wire. Background technique [0002] As the carrier of electric energy, overhead transmission line conductor occupies an extremely important position in the composition of transmission lines. In order to safely and reliably transmit more electric energy, many domestic scientific and technological workers have been working hard to find more ideal new materials as carriers for electric energy transmission. For a long time, we have successively developed ACSR with good anti-corrosion performance, rare earth ACSR, high-strength ACSR, heat-resistant aluminum alloy strand, and large-section expanded-diameter ACSR, etc. With the continuous advancement of science and technology, researchers continue to try to use organic composite materials instead of metal materials as the core material of wires, a...
