High-frequency electronic transformer wire technology explained

-From enameled wire to copper strip: The “vascular system” for electrical energy conversion

I. Comparison of core wire types and characteristics

1. Enameled wires: “nerve fibers” for high-frequency scenarios

Innovation Direction:

• Composite stranding: UEW stranding reduces skin effect (100kHz loss reduced by 40%)
• Nano-coating: AIW surface coated with Al?O? to increase withstand voltage up to 3kV/mm

2. Triple insulated wire: the “ultimate defense” against safety and high voltage.

Structure Analysis:

1. Inner layer: polyamide film (impulse voltage resistance 1kV)
2. Middle layer: Highly insulating spray paint (dielectric strength >30kV/mm)
3. Outer layer: glass fiber (resistant to mechanical damage)

Performance Benchmarking：

• Destructive voltage: TEX-E series up to 10kV (UL certification number E123456)
• Temperature class: Class F (180°C continuous operation)

3. Copper strips: the “double-sided hand” of high current and EMI suppression

• Winding Application: Thickness 0.1-1.0mm, 300% higher current-carrying capacity than round wire
• Shielding design: Inner shielding: 0.05mm copper foil + polyimide tape (temperature resistance 260℃) Outer shielding: full overlay welding, EMI suppression ≥45dB@100MHz

II、LPEMA's Supply Chain Advantage: Integrating the World's Top Wire Technologies

1. Rigorous supplier selection system

LPEMA has deep cooperation with global head wire manufacturers to build a pyramid supply chain:

• Top partners: Furukawa TEX-E, Totoku TIW-3, European Superconducting Materials Laboratory.
• Certification Matrix: All wires are certified by UL, IEC, MIL-STD-883H, etc., and can be traced back to the original batch.

2. Technology integration capabilities

• UEW/UEW-NY: Adopting Tanaka nano-coating process to increase solder yield to 99.99%.
• Triple insulated wire: Furukawa TEX-E series exclusive customized voltage resistance specification (12kV pulse withstand)
• Copper strip processing: Germany Schlenk precision calendering technology, thickness tolerance ±0.001mm

3. Customized Service Guarantee

• 72-hour response: Relying on the global stocking network of three warehouses (EU/North America/Asia), urgent orders are delivered directly to the production line.
• Free DFM Optimization: Based on suppliers' material database, automatically generate winding/heat dissipation/EMI optimization solutions.
