Import Tips
• Document frequency response curve (20Hz-20kHz) to distinguish audio-specific windings from power applications
• Use vacuum impregnation proof to demonstrate insulation quality required for transformer safety standards
• Pair with transformer housing import records for assembly verification if claiming parts status
