Electromagnetic wire, also known as winding wire, is an insulated wire used to make coils or windings in electrical products. Electromagnetic wire is usually divided into enamelled wire, wrapped wire, enamelled wrapped wire and inorganic insulated wire.
Electromagnetic wire is an insulated wire used to manufacture coils or windings in electrical products, also known as winding wire. The electromagnetic wire must meet the requirements of various uses and manufacturing process. The former includes its shape, specification, ability to work under short-term and long-term high temperature, strong vibration and centrifugal force under high speed in some cases, electrical resistance, breakdown resistance and chemical resistance under high voltage, corrosion resistance in special environment, etc. The latter includes tensile, bending and wear during winding and embedding, as well as swelling and corrosion requirements during impregnation and drying.
Electromagnetic wires can be classified according to their basic composition, conductive core and electrical insulation. Generally, it is classified according to the insulating material and manufacturing method used in the electrical insulating layer.
The use of electromagnetic wires can be divided into two types:
1. General purpose: it is mainly used for motors, electrical appliances, instruments, transformers, etc. to produce electromagnetic effect through winding resistance coil, and use the principle of electromagnetic induction to convert electric energy into magnetic energy.
2. Special purpose: applicable to electronic components, new energy vehicles and other fields with special characteristics. For example, microelectronic wires are mainly used for information transmission in the electronic and information industries, while special wires for new energy vehicles are mainly used for the production and manufacturing of new energy vehicles.
