Abstract

The invention relates to an electromagnetic wire for a nuclear power unit, comprising an enamelled copper round wire and an insulating layer wrapped around the enameled wire, the enameled copper round wire is an aromatic high-temperature-resistant polyimide enameled wire; the insulating layer is composed of It is composed of single or double glass fiber wrapping and external coating of boric acid modified high temperature resistant silicone resin. The invention solves the defects in the prior art that the electromagnetic wire cannot withstand high temperatures above 250°C for a long time, has poor nuclear radiation resistance, and has poor resistance to high and low temperature cold and heat shocks, and obtains a kind of wire with excellent nuclear radiation resistance and cold and heat shock resistance. It is a magnet wire with excellent performance, which not only has the excellent adhesion and flexibility of conventional magnet wire, but also can withstand high temperatures of 250°C and above for a long time. This electromagnetic wire can be used in insulation technology fields such as military industry, aerospace, 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...
