Aluminum winding wire is a main variety of winding wire, which is composed of two parts: conductor aluminum wire and insulation layer. After annealing and softening, bare aluminum wire is made by repeated painting and baking. However, it is not easy to produce a product that meets the requirements of the standard and meets the requirements of customers. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various aluminum winding wires It will be different, but all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.
Aluminum winding wire is the main raw material for products such as motors, appliances, and household appliances. In particular, the power industry has achieved sustained and rapid growth in recent years. The rapid development of household appliances has brought a wider field to the application of enameled aluminum wires , And the ensuing demand for enameled wire is higher.
The aluminum winding wire price generally depends on the type of paint on its surface, the thickness, the temperature resistance level and the thickness of the aluminum wire.
A general purpose aluminum winding wire(ordinary wire): mainly used for winding wires of general motors, electrical appliances, instruments, transformers and other working occasions, such as polyester enameled wire and modified polyester enameled wire. Only a small amount of domestic lacquer for single-coated polyesterimine enameled wire is used, but voltage instability is still a concern for manufacturers. Direct solderability polyesterimide lacquer has been successfully developed by the Cable Research Institute
Heat-resistant aluminum winding wire : mainly used for winding wires of motors, electrical appliances, instruments, transformers and other working environments working at 180 ℃ and above, such as polyester imide enameled wire, polyimide enameled wire, polyester enameled wire Enamel / polyamideimide composite enameled wire.
Special purpose aluminum winding wire: refers to the winding wire with certain quality characteristics and used in specific occasions, such as: polyurethane enameled wire (direct welding), self-adhesive enameled wire.
