Abstract

The invention discloses an aramid-fiber varnished wire, and the varnished wire comprises a conductor. The external surface of the conductor is wrapped by an aramid fiber insulating varnish film. The invention also provides a production method for the aramid-fiber varnished wire. The aramid-fiber varnished wire is excellent in mechanical performance, flame retardation performance, electrical isolation performance, heat resistance performance and chemical corrosion resistance performance, and can be used for a field which exerts stricter requirements on the performances of wires and cables.

Description

technical field [0001] The present invention relates to an electric wire. Background technique [0002] At present, the application fields of wires and cables continue to expand, and the performance requirements for wires and cables are becoming more and more stringent. Wires and cables are required to have excellent mechanical, electrical insulation, flame retardant, heat resistance, and chemical corrosion resistance. [0003] However, there is still no insulated enameled wire that can well solve the above technical problems. Contents of the invention [0004] The purpose of the invention is to propose a high-performance aramid enameled wire for the technical problem that the performance of the current enameled wire is not excellent enough. [0005] To achieve the above object, the present invention provides an aramid enameled wire, which includes a conductor, and the outer surface of the conductor is covered with an aramid insulating varnish film. [0006] Preferably, ...
