Abstract

The invention provides a copper compound carbon fiber material and a preparation method and application thereof. The copper compound carbon fiber material is prepared from the following components inpercent by mass: 50-75% of carbon fibers, 25-50% of copper and the balance of inevitable impurities. The copper compound carbon fiber material can improve the dispersing uniformity of copper in the carbon fibers by limiting proportion of the carbon fibers and copper, so that the conducting uniformity, the conductivity, the flexibility, the strength and the reliability of the copper compound carbonfiber material are improved. When the copper compound carbon fiber material is used as a high voltage ground lead material, compared with a same condition, the total mass of the ground lead is 1 / 4 ofthe copper material ground lead in a same current-carrying condition and the total mass of the high voltage ground lead is about 1 / 3-1 / 2 of that of a conventional high voltage ground lead. In addition, the copper compound carbon fiber material provided by the invention can be placed by winding and is not broken or corroded. Matched with a detachable insulating operation rod, it is convenient to carry and use in overhaul 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 ...
