As the application of lacquer wires has become increasingly demanding and increasingly stringent, it has also developed a composite lacquer wire. The inner and outer paint films are composed of different high-molecular materials, such as polyester imine/lactam lacquer.
One of the important items in the wrapping wire around the wrapping wire. In the early days, cotton yarns and yarns were used, which were called yarn wrapped yarns and wire wrapped yarns. They were used in electrical machines and electrical appliances. Due to the large insulation thickness and low heat resistance, most of them have been replaced by Lacquer wire. Currently only used for high-frequency winding lines. In large and medium-sized winding lines, when the heat resistance level is high and the mechanical strength is high, glass-fiber-wrapped wire is also used, and a suitable adhesive paint is used during the manufacturing process.
In the wrapped wire, the paper envelope still occupies a similar position and is mainly used in oil immersed transformers. The oil-paper insulation formed at this time has excellent dielectric properties, low price, and long life. In recent years, the rapid development of the film has been wrapped around a thin film, mainly including a polyester film and a polyimide film.
Insulation Insulation Lines When heat-resistant grades are required to exceed the limits of organic materials, they are usually coated with inorganic insulating lacquer. The existing inorganic insulation line can be further divided into glass film, oxide film and ceramics.
