FAQ

Q1. How are the temperature resistance grades of enameled wires classified? And which scenarios are suitable for different grades?
A1. Common temperature resistance grades are as follows:
- 130°C (Class B): It is a general-purpose type, widely used in household appliances and small motors.
- 155°C (Class F): Applicable to industrial motors and transformers. It has better heat resistance compared to Class B.
- 180°C (Class H): Mainly used in high-temperature working environments such as high-temperature motors, transformers, etc.
- above 180°C (Class C): It is suitable for special electronic devices in extremely high - temperature and high - pressure environments, such as motors and transformers in the aerospace and nuclear industries.

Q2. What is the wire diameter range of the enameled wires?
A2. The conventional wire diameter range is from 0.035mm to 1.000mm. Non-standard customization is also supported.

Q3. Do the enameled wires meet the RoHS environmental protection standard?
A3. Yes, the products have passed the EU RoHS certification, and the certificate number is E326617.

Q4. How to select enameled wires for high-frequency transformers?
A4. The key indicators are as follows:
- Low skin effect: It is recommended to choose litz wires or multi-strand thin wires.
- Low dielectric loss: Enameled wires with polyurethane or polyesterimide paint can be selected.
- Self-adhesiveness: It helps to reduce the impregnation process.
