Glass fiber and carbon fiber composite core for wire of transmission line

Abstract

The invention discloses a glass fiber and carbon fiber composite core for a wire of a transmission line, which is characterized by consisting of 50 to 55 percent of carbon fibers, 10 to 15 percent of glass fibers and 30 to 40 percent of resin and auxiliary materials. Carbon fiber yarns pass through fibers-converging stander to be converged into a rounded body to be drawn outward; glass fibers cover the carbon fiber rounded body from a plurality of layers of creels and are drawn outward; and the carbon fiber rounded body covered by glass fiber yearns is synchronously drawn outward to pass through a mould. A well-stirred resin raw material can be poured into a resin storage tank 5 after being sieved by an 80 mesh sieve. The temperatures of a curing region and a forming region in the heating mould are set to be 200+ / -10 DEG C and 140+ / -10 DEG C respectively, and the heating mould is electrically heated. A heating system of an extruder is started, and the temperatures of heating areas are adjusted according to process requirements. The class fiber and carbon fiber composite core can well solve the problem of the combination of a thermosetting process and a thermoplastic process, thereby achieving excellent product quality and fulfilling a preset technical solution target.

Description

technical field [0001] The invention relates to the field of overhead transmission line conductors, in particular to a composite core of glass fiber and carbon fiber for transmission line conductors. Background technique [0002] With the continuous progress of material technology, at the end of the 20th century, people tried to use organic composite materials instead of metal materials to make the core material of the wire, and developed a new composite material synthetic core wire. This kind of wire gives full play to the characteristics of organic composite materials. Compared with various overhead wires at present, it has the characteristics of light weight, high strength, good thermal stability, low laxity, large carrying capacity, and corrosion resistance. In terms of land, material saving, environmental protection, and improvement of power transmission capacity, it has a good application prospect, especially suitable for the transformation of old lines. In the 1990s,...

AI Technical Summary

Problems solved by technology

Some people in China try glass fiber reinforced plastics and carbon fiber composite cores to make reinforced cores (FRP). Although they have the advantages of light weight, high strength, corrosion resistance, antistatic and anti-biting, the production rate is full and the bending radius is large.
