Enameled wire with high electrical conductivity and preparation method thereof

Abstract

The invention discloses an enameled wire with high electric conductivity, including a conductive core layer, a tensile fiber layer is arranged on the surface of the conductive core layer, a tin platelayer is arrange on that surface of the tensile fiber layer, a surface of that tin plate layer is provide with an insulating paint layer, the conductive core layer comprises a nano silver-copper alloycore, an inorganic insulating micro-particle layer is arranged on the surface of the nano silver-copper alloy core, the tensile fiber layer is wound on the surface of the inorganic insulating micro-particle layer by a plurality of carbon fiber filaments alternately and helically in the reverse direction. According to the invention, the conducting core layer of nanometer silver copper alloy is obtained through combination of silver and copper, so that a conducting performance far higher than that of a copper core enameled wire can be achieved and comparatively high stability is realized. The inorganic insulating micro-particle layer formed on the surface of the nano-silver-copper alloy core can also solve the problems of the silver plating layer, and the nano-silver-copper alloy core can be coated to play the role of insulation and have extremely high heat resistance.

Description

technical field [0001] The invention relates to the technical field of enameled wire conduction, in particular to an enameled wire with high electrical conductivity and a preparation method. Background technique [0002] Enameled wire is an important accessory of electrical equipment. Enameled wire is composed of a conductor and a multi-layer insulating varnish coated on the conductor. With the continuous and rapid development of the social power industry, it has brought a very broad market prospect to enameled wire. With higher requirements, the traditional enameled wire generally includes the copper wire body and the enamelled layer. The enameled wire of this structure is usually too simple to consider the influence of environmental factors. In some special fields, it is usually installed and practical. In the process, it is more or less necessary to bend and pull the enameled wire, and if the enameled wire is used to make a large product, the bending of the wire body may ...

Problems solved by technology

[0004] However, for precision equipment that requires extremely high conductivity, there is an alloy silver wire to increase the conductivity, but it needs to add various elements such as palladium, gold, nickel, platinum, etc. The production process is more complicated and the cost is higher.
