The classification and use of enameled wire There are many ways to classify enameled wire, and the common classification includes the following:
1. Classification by insulation materials
1. Polyester enamelled Wire (PEW)
- Use: Commonly used in general motors, electrical appliances, instruments, transformers, etc. The price is relatively low, with better electrical and mechanical properties.
- For example: motor windings in small household appliances.
2. Polyester imine enamelled Wire (EIW)
- Application: Suitable for motors and electrical appliances working in high temperature environment, with high heat resistance and chemical resistance.
- For example: motor windings in automobile engines.
3. Polyamide-imide enamelled Wire (AIW)
- Use: For applications requiring high heat resistance and mechanical strength, such as aerospace equipment, high-speed motors, etc.
- For example: certain electrical equipment on an aircraft.
4. Polyurethane enamelled Wire (UEW)
- Use: Mainly used for occasions requiring high softness, such as power tools, audio equipment, etc.
- For example: winding of portable power tools.
Second, according to the conductor material classification
1. Copper enamelled wire - Use: widely used in various electrical equipment, because of its good electrical and thermal conductivity.
- For example, power transformers, motors, etc.
2. Aluminum enamelled wire
- Use: Used in some occasions with strict weight requirements or cost sensitivity, such as some household appliances.
- For example: some light fan motor windings.
Three, according to the shape of the enamelled wire classification
1. Round enamelled wire
- Use: the most common, suitable for most conventional motors, electrical appliances, etc.
- For example, the winding of an ordinary motor.
2. Flat enamelled wire
- Use: It is often used in situations where space is limited and large cross-sectional area is required, such as large transformers, reactors, etc.
- For example: winding of large power transformers.
In short, the classification of enameled wire is rich and diverse, and different types of enameled wire play an important role in different fields and equipment to meet various specific electrical and mechanical performance requirements.
