High-strength high-conductivity enameled copper alloy wire

Abstract

The invention discloses a high-strength high-conductivity enameled copper alloy wire which comprises a conductor layer and an insulated layer wrapped outside the conductor layer. The conductor layer is a copper alloy wire which is made of an alloy material of cooper and magnesium or copper and silver or copper, chromium and zirconium. The high-strength high-conductivity enameled copper alloy wire does not soften in a high-temperature environment, and does not deform or neck down when subjected to high-pressure thermal shock. The enameled wire cannot be lengthened during a winding process of electrical equipment. Therefore, the fact that resistivity of the enameled wire can be controlled is ensured, and high stability of the electrical equipment is obtained.

Description

technical field [0001] The invention relates to a high-strength and high-conductivity enamelled copper alloy wire. Background technique [0002] Enameled wire is the material for manufacturing motor and transformer windings. The function of the enameled wire winding is to convert electrical energy into mechanical energy and adjust the voltage. The enameled wire is composed of two parts: a conductor and a bonding layer. The conductor material is copper, aluminum and other high-conductivity materials. The insulating layer Usually insulating paint. The current enameled wire production technology generally uses pure copper and pure aluminum wires as conductor materials. Due to the limitation of material capacity, the material strength is low. During the winding process, the enameled wire is easily stretched and thinned, resulting in an increase in the resistance of the enameled wire. Moreover, copper and aluminum enameled wires will be deformed and necked after being subjected ...
