Type of magnetic wire
Type of magnetic wire is divided into enameled wire, wrapping wire, insulated wire, combined wires and others,Mainly used in motors, electrical appliances, instruments, transformers, etc., to generate electromagnetic effects by winding coils, and use the principle of electromagnetic induction to achieve the purpose of converting electrical energy to magnetic energy
Enameled wire
The conductor is coated with a corresponding lacquer solution, and then the solvent is volatilized and the lacquer film is solidified and cooled to make it. Enameled wire can be divided into polyester enameled wire, polyesterimide enameled wire, polyamideimide enameled wire, polyimide enameled wire, polyesterimide/polyamideimide enameled wire, corona resistant enameled wire, and oily enameled wire according to the insulating varnish used. Paint, acetal paint, polyurethane enameled wire, etc. Sometimes it is also classified according to the particularity of its use, such as self-adhesive enameled wire, refrigerant-resistant enameled wire, etc.
Wrapping wire
An important variety in winding wires. In the early days, cotton yarn and silk, called yarn covered wire and silk covered wire, were used in motors and electrical appliances. Due to the large insulation thickness and low heat resistance, most of them have been replaced by enameled wires. At present, it is only used as a high-frequency winding wire. In the large and medium-sized winding wires, when the heat resistance grade is higher and the mechanical strength is higher, the glass fiber covered wire is also used, and the appropriate adhesive paint is used in the manufacture.
Insulated wire
When the heat resistance rating exceeds the limit of organic materials, inorganic insulating varnish is usually used. The existing inorganic insulated wires can be further divided into glass film wires, oxide film wires and ceramic wires.
other
There are also combined wires, transposed wires and so on.
