Abstract

The invention provides a copper composite carbon fiber material and its preparation method and application. In terms of mass percentage, the copper composite carbon fiber material is composed of the following components: carbon fiber 50-75%, copper 25-50%, and the balance is unavoidable Impurities. The copper-composite carbon fiber material can effectively improve the dispersion uniformity of copper in the carbon fiber by limiting the ratio of carbon fiber and copper, and improve the conductive uniformity, conductivity, flexibility, strength and reliability of the copper-composite carbon fiber material. When used as a high-voltage grounding wire material, under the same conditions, the total mass of the grounding wire is 1 / 4 of that of the copper material grounding wire under the same current-carrying conditions, and the overall mass of the high-voltage grounding wire is about 1 / 3-1 of the traditional high-voltage grounding wire / 2; In addition, the composite carbon fiber material provided by the present invention can also be wound and placed without breaking or being corroded, and it is equipped with a detachable insulating operating rod, which is convenient for carrying and maintenance work.

Description

technical field [0001] The invention relates to the technical field of preparation of metal composite materials, in particular to a copper composite carbon fiber material and its preparation method and application. Background technique [0002] The high-voltage grounding wire is mainly used in the construction process of electric lines and substations, which can avoid the danger of electric shock caused by electrostatic induction or false closing operation of workers near the charged body, and play a role in ensuring the safety of personal and property. [0003] At present, the high-voltage grounding wire is mainly composed of insulating operating rods, wire clamps, grounding wires and grounding clamps. Among them, the insulating operating rod is mainly made of epoxy resin material with high insulating performance and high mechanical strength and glass fiber. At the same time, a rubber sheath with high insulating strength is installed at the position of the operating handle ...
