Extrusion Leeds line is a Leeds line processed through extrusion technology, with the following characteristics and applications:
>> Characteristic
High conductivity and heat dissipation: Copper alloy or pure copper conductor is used, which has excellent conductivity. At the same time, the heat dissipation function is achieved by optimizing the insulation layer structure (such as opening through holes), reducing the heat loss during high-frequency operation
Strong insulation performance: The outer extruded material provides good insulation protection, and some products have also passed VDE, UL and other certifications, suitable for high safety requirements scenarios
Flexibility and processability: Extrusion technology can produce rectangular or square cross-sections with high filling rate, making it easy to wind and improve motor power density; Simultaneously possessing self adhesiveness, suitable for complex assembly requirements
>> Application Area
New energy vehicles:
Car heating system: Used for seat heating, steering wheel heating and other scenarios, achieving efficient heat transfer through extrusion technology
Wireless charging device: Smart twisted wire (such as OSP18 series) is designed specifically for wireless charging in cars, with both fast welding and hot air self-adhesive properties
Industry and Electricity:
Utilizing the low eddy current loss characteristics of high-frequency transformers, frequency converters, and other scenarios to improve efficiency
Military industry and special scenarios:
Electromagnetic catapults, acceleration coils and other military fields, as well as complex environments that require concealment and high temperature resistance
In summary, extruded Leeds wire has demonstrated significant advantages in high-frequency, high-power, and special environmental applications due to its structural optimization and material properties.
