Abstract

The invention discloses an insulated wire, mainly composed of copper wire and paint layer, its character: it coats a protective layer on the copper wire. Its construction is reasonable. The protective layer slows down the oxidization of the copper wire under 200 deg.C and above, which prolongs the useful life of products and ensures the working performance of products. It has promotional vale.

Description

Technical field: [0001] The invention relates to a wire, in particular to a direct solderable enameled wire. Background technique: [0002] At present, for enameled wires commonly used, when the temperature is at or above 200°C, the copper will be oxidized at an accelerated rate. At this time, the copper will produce pitting and embrittlement. This oxidation will eventually damage the paint film and cause the winding to fail. Invention content: [0003] The technical problem to be solved by the present invention is to provide an enameled wire that can effectively overcome the above defects and effectively protect copper wires. The technical solution adopted by the present invention to solve the technical problem is that an enameled wire is mainly composed of a copper wire and a paint layer, and its characteristic is that a protective layer is coated on the copper wire. Due to the adoption of the above scheme, it is not difficult to conclude that the present invention has ...
