Abstract

The invention discloses a new type of high-temperature insulating wire, a preparation method and coating equipment thereof, including a wire core and an insulating coating. The oxidation process uses a special type and concentration of electrolyte, on the surface of the aluminum conductor core, under the combined action of plasma discharge, thermochemical reaction and thermal action, a layer of α-Al is grown in situ. 2 o 3 , γ‑Al 2 o 3 It is a high-temperature insulating layer with main components. The insulating layer can withstand the temperature below 550° C., and the withstand voltage can reach 1300V.

Description

technical field [0001] The invention belongs to the technical field of wires, and in particular relates to a wire, a preparation method and coating equipment. Background technique [0002] At present, the insulation of wires mainly depends on wrapping insulating materials, such as rubber materials, which have poor high temperature resistance; at the same time, in order to improve the insulation effect, a thick layer of rubber needs to be wrapped, which is not conducive to use. Therefore, coating an insulating layer directly on the aluminum alloy will expand the application range of the aluminum alloy and make it have a broader application prospect in the field of strong electricity. Contents of the invention [0003] The invention provides a high-temperature insulated wire, which includes a wire core and an insulating coating, and the wire core is made of an aluminum alloy material; the aluminum alloy material includes: aluminum element, silicon element, copper element, ma...
