Woven fiber core overhead wire

Abstract

The invention belongs to an overhead wire which takes two or more than two woven fibers as a wire carrying core, in particular to a woven fiber core overhead wire. Presently, the conventional fiber composite core wire adopts a single kind of high strength fiber, has the structure of a wire beam or a wire cable, is formed by soaking in epoxy resin and performing pultrusion and thermocuring forming, and has poor bending performance and impact resisting performance. The invention aims to provide the woven fiber core overhead wire. The woven fiber core overhead wire is characterized in that: a bar-shaped woven fiber core is formed by weaving two or more than two kinds of fibers two-dimensionally or three-dimensionally, and serves as the carrying core of the wire so as to enhance the longitudinal tensile strength of the wire and improve the lateral bending performance and the impact resisting performance of the wire. So, the defects of the conventional fiber composite core wire are overcome.

Description

technical field [0001] The invention belongs to an overhead wire with two or more kinds of braided fibers as the wire carrying core, specifically a braided fiber core overhead wire. Background technique [0002] Common fiber composite core conductors, such as Chinese patent application 038092840 aluminum conductor composite core reinforced cable and its manufacturing method, Chinese patent 200520072074.2 carbon fiber composite core aluminum stranded wire and insulated cable, U.S. patent 20040131834, etc., although high-strength fibers are used, their Combined into a single type of fiber, the structure is tow or wire, impregnated with epoxy resin, pultruded, and thermoset to form a fiber composite core. Its bending and collision resistance performance is poor. Once a few fibers break, it will affect the tensile strength of the overall fiber composite core, and there is a tendency of cracking and expanding damage along the direction of the tow. For the power line in operation,...

Problems solved by technology

Its bending and collision resistance are poor. Once a few fibers are broken, it will affect the tensile strength of the overall fiber composite core, and there is a tendency to crack and expand damage along the direction of the tow. It is easy to break the power line in operation. Line major equipment accidents and personal casualties, so that the application of this type of wire is restricted
