Copper winding materials
Copper Foil for Transformer Windings
Rolled copper foil provides the current-carrying layers in a foil-wound coil. Select thickness and width for the winding design, then specify temper, edge condition and insulation requirements. For high-frequency designs, assess winding losses using the actual layer arrangement and operating frequency.
Construction and specification
- Material construction
- Specified copper grade and temper
- Product form
- Rolled foil
Selection and processing
At high frequency, winding geometry and the arrangement of layers affect AC loss as well as DC resistance. Include frequency, waveform, insulation, winding tension and lead connections with the foil drawing; compare the assembled coil at the required temperature rise.
Standards context
Use the drawing and a material/form-specific purchase specification. Round-wire references do not qualify rolled strip, foil or flat wire. Confirm edition, methods and acceptance criteria.
