Enameled wire and glass-covered wire are both main types of winding wires, and there are some differences between them in structure, characteristics and applications.

Enameled wire is composed of two parts: conductor and insulation layer. After annealing and softening, the bare wire is painted and baked several times. Its production process is affected by factors such as raw material quality, process parameters, production equipment and environment, resulting in different quality characteristics of various enameled wires, but they all have four major properties: mechanical properties, chemical properties, electrical properties and thermal properties. Enameled wire is the main raw material for products such as motors, electrical appliances and household appliances. Especially in the context of the sustained and rapid growth of the power industry and the rapid development of household appliances in recent years, higher requirements have been put forward for enameled wire.

Glass-covered wire is composed of glass wire wrapped around aluminum conductor and adhesive paint with required temperature resistance index and compatibility. This insulating layer has certain wear resistance, adhesion, flexibility and voltage resistance, so glass-covered wire has good resistance to thermal shock and overload. It is mainly suitable for winding wires of high, low voltage, medium and large capacity motor and electrical products.

In general, there are obvious differences between enameled wire and glass-covered wire in terms of structure, characteristics and application. The choice of wire depends mainly on the specific application requirements and working environment.
