Frequently Asked Questions
Q
What standards do your flat wires comply with?
Our flat wires are manufactured in strict accordance with GB/T 7673-2008 and corresponding Enterprise Standards. These standards govern dimensional tolerances, insulation performance, electrical conductivity, and mechanical properties, ensuring consistent quality across all product lines.
Q
What size ranges are available for aluminum flat wire?
Aluminum flat wires are available with a narrow side ranging from 1.00 mm to 8.00 mm and a wide side from 3.00 mm to 25.00 mm. For sizes outside this range, customized production is available upon request.
Q
What are the available dimensions for copper flat wire?
Copper flat wires come with 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 can be produced to meet specific design or technical requirements beyond the standard range.
Q
What is the breakdown voltage of polyimide film wrapped wire?
The minimum breakdown voltage varies by wrapping process: 6000 V for 2-layer self-locking or opposite-direction wrapping (0.15 mm insulation thickness), and 7000 V for 3-layer opposite-direction wrapping (0.23 mm insulation thickness), all with a tolerance of ±0.03 mm.
Q
Can I order custom-sized flat wire outside the standard specifications?
Yes. If your required dimensions or specifications fall outside the standard ranges listed for either aluminum or copper flat wire, customized production can be arranged. Please contact us with your specific technical requirements and we will provide a tailored solution.
Q
What are the typical applications of aluminum vs. copper flat wire?
Aluminum flat wire is widely used in transformers, reactors, and electric motor windings where lightweight construction and cost-effectiveness are priorities. Copper flat wire is preferred for high-power applications, precision electronic devices, and transformers where superior electrical conductivity, heat resistance, and mechanical strength are required.
