Abstract

The invention discloses a resin-based reinforced fiber compound core, an overhead conductor and a manufacturing method of the resin-based reinforced fiber compound core. The resin-based reinforced fiber compound core comprises reinforced fibers and thermoplastic resin, the reinforced fibers are bonded and solidified in the thermoplastic resin, the reinforced fibers comprise longitudinally arranged fibers and twined fibers, and the twined fibers are twined or woven outside the longitudinally arranged fibers in a spiral mode. The overhead conductor comprises the resin-based reinforced fiber compound core and an aluminium conductor arranged on the outer side in a twisting mode, and is formed through the working procedures of tension stringing, resin impregnation, surplus resign removing, preforming, lapping, extrusion and pulling forming, on-line sintering, twisting and wire forming and reel forming. Through the mode, according to the resin-based reinforced fiber compound core, the overhead conductor and the manufacturing method of the resin-based reinforced fiber compound core, the recoverability rate of the resin is high, the radial and longitudinal mechanical properties of the resin-based reinforced fiber compound core is enhanced, the manufactured overhead conductor is good in tensile strength and bending resistance, and production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of overhead wires, in particular to a resin-based reinforced fiber composite core, an overhead wire and a manufacturing method thereof. Background technique [0002] Composite core wire has the characteristics of low sag, high temperature operation, and large tension / weight ratio. The related patent 03809284.0 discloses a composite core composed of two or more types of fibers longitudinally oriented and substantially continuous in a thermosetting resin matrix (referred to as Composite core) and overhead power transmission conductors (referred to as conductors) as reinforced cores. The composite core uses high-strength longitudinal fibers with a volume ratio of at least 50% and thermosetting resins as fiber binders, which are formed by pultrusion and heat curing. core. Due to the restriction of process and resin selection, the cured resin is only limited to thermosetting resin. This composite core still has ...
