An ice-melting wire and its manufacturing method

Abstract

The invention provides an ice melting wire and a fabrication method thereof. The ice melting wire comprises an electric conductor (2) and a carbon fiber core bar (5), wherein the carbon fiber core bar (5) comprises an electric conduction heating body (1) and a carbon fiber heat transfer layer (53) wrapping outside the electric conduction heating body (1), electric conductors (2) wraps outside the carbon fiber core bar (5), the electric conductors (2) and the carbon fiber core bar (5) are in electrical insulation, and the electric conduction heating body (1) and the electric conductors (2) are in electrical insulation. The fabrication method comprises the following steps of firstly, coating the outer surfaces of the carbon fiber core bar (5) and the electric conductors (2) with heat conduction coating layers (3); secondly, twisting the carbon fiber core bar (5) and the electric conductors (2) until the wire with required diameter and length is achieved; and finally, coating the outer surface of the wire with a hydrophobic coating layer (4). The ice melting wire has remarkable advantages of high strength, light weight, low sag, corrosion resistance and the like, an ice melting effect of ice coating of the wire can be achieved, and power failure is not needed.

Description

technical field [0001] The invention relates to the technical field of wires, in particular to an ice-melting wire and a manufacturing method thereof. Background technique [0002] Traditional power transmission wires mostly use steel-cored aluminum stranded wires, and its basic structure is to wind aluminum stranded wires outside the steel core wires. This kind of steel-cored aluminum stranded wires has a heavy weight. When it is used in the area covered with ice, the conductor is easy to freeze, and the continuous thickening of the ice layer increases the ice-covered weight of the conductor, and it is easy to cause the transmission conductor to break due to its own strength and insufficient carrying capacity, resulting in Power outage accident. [0003] In order to prevent the power transmission wire from being broken due to the heavy ice coating, it is necessary to timely melt the ice on the power transmission wire. At present, in the field of deicing and anti-icing tec...

AI Technical Summary

Problems solved by technology

The actual ice-melting effect of the traditional heat-resistant aluminum alloy strand with steel core is not ideal. Moreover, due to its heavy weight and poor corrosion resistance of the steel core, it should be used in areas with high cold, high altitude, and heavy ice. There are still many potential safety hazards in the overhead transmission lines
