Production process of carbon fiber composite core and large-tension high-frequency composite core wire system

Abstract

The invention discloses a production process of a carbon fiber composite core and a large-tension high-frequency composite core wire system. The production process of the carbon fiber composite core comprises the steps of S1 rearrangement: rearranging carbon fibers and reinforced fibers through a wire passing plate; S2 resin immersion: immersing the carbon fibers and the reinforced fibers into resin; and S3 pre-curing the carbon fibers for several times: selecting 1 / 3 of the carbon fibers immersed in the resin, and preparing a first carbon fiber bundle from the selected carbon fibers through preheating and a first pre-forming mold; circumferentially arranging the remaining carbon fibers outside the first carbon fiber bundle to form a second carbon fiber layer, and manufacturing the secondcarbon fiber layer through preheating and a second pre-forming mold. The production process can effectively prevent the carbon fibers in the large-diameter composite core from being exposed, the process tool is simple, the tensile strength of the produced carbon fiber composite core is larger than or equal to 2600 MPa, the breaking force is large, and the line sag can be effectively reduced.

Description

technical field [0001] The invention relates to the field of cables, in particular to a production process of a carbon fiber composite core and a high-tension high-frequency composite core wire system. Background technique [0002] Carbon fiber composite core conductor (ACCC) is a new type of conductor for overhead transmission lines. Its outstanding features are light weight, tensile resistance, good thermal stability, small sag, strong flow capacity per unit area and corrosion resistance. Especially suitable for coastal and mining areas where the corrosion intensity is high, the pollution intensity is high, and the wires are easy to dance. It can meet the requirements of building a resource-saving and environment-friendly power grid, and has a good application prospect in power grid transmission lines.
