? Frequently Asked Questions
Q
What standards do your aluminum and copper flat wires comply with?
Our flat wires are manufactured in strict accordance with GB/T 7673-2008 and corresponding Enterprise Standards. This ensures high precision, consistency, and reliability across all product lines, meeting the demanding requirements of electrical and electronic industries.
Q
What size range is available for aluminum flat wire?
Our aluminum flat wires have a narrow side ranging from 1.00 mm to 8.00 mm and a wide side ranging from 3.00 mm to 25.00 mm. For dimensions outside this range, customized production is available upon request.
Q
What size range is available for copper flat wire?
Our copper flat wires feature a narrow side from 0.90 mm to 6.00 mm and a wide side from 2.00 mm to 16.00 mm. Custom sizes beyond this range can also be arranged to meet your specific technical requirements.
Q
What is the minimum breakdown voltage for polyimide film wrapped wire?
The minimum breakdown voltage varies by wrapping configuration. For 2-layer polyimide film wrapping (both self-locking and opposite direction), the minimum is 6000 V. For 3-layer opposite direction wrapping with 0.23 mm insulation thickness, it reaches a minimum of 7000 V.
Q
Can you produce custom-sized flat wires beyond the standard specifications?
Yes. If your required size or specification exceeds the standard range for either aluminum or copper flat wires, we can arrange customized production to precisely meet your design and technical needs. Please contact us with your detailed requirements.
Q
What are the typical applications for your flat wires?
