Abstract

The invention relates to an electromagnetic wire for a nuclear power unit and a preparation method of the electromagnetic wire. The electromagnetic wire comprises a circular enameled copper wire and an insulating layer which wraps the circular enameled copper wire, the circular enameled copper wire is aromatic high-temperature-resistant polyimide enameled wire, and the insulating layer is formed by coating single or double fiber glass with boric acid modified high-temperature-resistant organic resin. The defects that the electromagnetic wire in the prior art is incapable of resisting high temperature over 250 DEG C for long time, is low in nuclear radiation resistance and is low in cold and thermal resistance caused by high and low temperature in the prior art are overcome; and the obtained electromagnetic wire is excellent in nuclear radiation resistance, cold and thermal shock performance, high adhesive force and high flexibility, and can withstand high temperature over 250 DEG C. The electromagnetic wire can be applied to the technical field of insulating in military industry, aviation and spaceflight, and nuclear power motors.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic wires for electricians, and in particular relates to an electromagnetic wire for nuclear power units and a preparation method thereof. Background technique [0002] Against the backdrop of the national policy of energy conservation, emission reduction, and vigorous development of new energy, nuclear power has become one of the key new energy sources due to its high quality, high efficiency, mature technology, strong continuous supply capacity, good economy, and low-carbon environmental protection. As we all know, nuclear power units require long life and high reliability. As the main component of the insulation structure of the main pump motor of nuclear power, the electromagnetic wire plays an unusual role. Electromagnetic wires for nuclear power units require not only excellent high temperature resistance, but also excellent nuclear radiation resistance. [0003] At present, the existin...
