Enamel coated flat wire is a specially designed winding wire with the following characteristics and uses:
>> Characteristic
1. High slot occupancy rate
Under the same winding space, the slot filling rate of enameled flat wire can reach over 95%, which is significantly higher than traditional round wire (about 78%), reducing coil volume and improving resistance and capacitance performance, meeting the requirements of high load scenarios
2. Excellent heat dissipation performance
The flat structure increases the cross-sectional area and heat dissipation area, effectively reducing the "skin effect" loss under high-frequency current, while improving high temperature resistance performance (such as 180 ° C high temperature resistance)
3. Lightweight and volume advantages
Flat wire takes up less space (saving 9-12%), is lighter in weight, and is suitable for fields with high lightweight requirements such as new energy vehicles and industrial robots
4. Heat resistance and insulation performance
The insulation paint layer has characteristics such as resistance to corona discharge, resistance to ATF oil, and resistance to ultra-high temperatures, which can withstand high voltage and high temperature impacts during motor operation and extend equipment life
5. Flexibility and adaptability
Flat wire is soft and bendable, suitable for complex wiring environments (such as inside precision electronic devices), reducing the risk of bending damage
6. High conductivity
The conductivity of copper conductors can reach 98% IACS, while that of aluminum conductors is about 61% IACS, reducing energy loss and improving transmission efficiency
>> Main Purpose
1. New energy vehicles
Used to drive core components such as motor windings and battery management systems, meeting high power density, high temperature resistance, and corona resistance requirements
2. Motor and Transformer
Improve slot occupancy and heat dissipation efficiency in Hair pin winding motors and transformer coils, optimizing electrical performance
3. Electronic appliances
Used for connecting wires of communication equipment coils, induction cooker heating elements, etc., to ensure signal stability and product safety
4. Aerospace and Military Industry
With high temperature resistance and corrosion resistance, it is applied in harsh environments such as aircraft electronic systems and rocket energy systems
5. Industrial automation
Efficient energy transfer in servo motors and industrial robots, supporting precision control requirements
Lacquered flat wire continuously expands its application scenarios through technological innovation, such as ultra narrow and ultra-thin design, and high toughness materials, especially in the fields of new energy vehicles and high-end manufacturing where demand growth is significant
| Film wrapped flat wire |
| Membrane wrapped flat wire is a membrane wrapped stranded wire that is rolled into a square or flat shape based on ordinary membrane wrapped twisted wire. In addition to the performance characteristics of ordinary membrane wrapped wire, it can also reduce the inter turn gap of transformer windings, thereby achieving a higher filling factor for transformers. |
