Problems solved by technology

However, the existing composite core is made of reinforcing fibers wrapped and cured by thermosetting resin. On the one hand, the curing characteristics of the thermosetting resin limit the production and processing speed of the composite core. Generally, the processing speed is about 1 m/min; During the composite core molding proces

Abstract

The invention relates to a thermoplastic composite core for an overhead conductor and a manufacturing method thereof. As the matrix fiber made of the thermoplastic material is used as the matrix material, the reinforcing fibers are dispersed among the matrix fibers, and the matrix fibers are bonded to each other into an integrated structure by the thermoplastic molding method, so that the reinforcing fibers are wrapped to form a composite core. As such, on that one hand, the matrix fib made of the thermoplastic material can be quickly molded into an integral body with the reinforce fiber without completely melting the matrix material and then solidifying molding as in the prior art, and therefore, the production efficiency is high; On the other hand, the manufacturing process does not completely melt the matrix fibers, and the matrix fibers do not adhere to the mold to generate waste, so the production cost is low.

Description

technical field [0001] The invention relates to a thermoplastic composite core body for overhead wires and a manufacturing method thereof. Background technique [0002] Overhead wires are wires used to carry current in power transmission. The overhead wires are suspended in the air. Due to the weight of the overhead wires, it is necessary to set up a transmission tower every other distance to carry the overhead wires. In order to strengthen the strength of the overhead wires, The center of the overhead conductor is generally equipped with a reinforcing core, and the surrounding of the reinforcing core is an aluminum stranded conductor. The traditional reinforcing core is a steel core, but the weight of the rigid core is relatively large. In order to reduce the weight of the overhead conductor, at the beginning of this century, the composite core is The fiber resin-based composite core is used as a reinforcing core to replace the traditional steel core to make a composite cor...
