💬 Frequently Asked Questions
What is the maximum number of strips available for CTC wire production?
The CTC strips range from 5 to 80 strips (odd or even), with a maximum overall height of 120mm and width of 26mm (tolerance ±0.05mm).
What are the available conductor dimensions for single conductors?
The single conductor thickness (a) ranges from 0.90 to 3.15mm, and the width (b) ranges from 2.50 to 13.00mm, both with a tolerance of ±0.01mm. The suggested width-to-thickness ratio is 2.0 < b/a < 9.0.
What types of CTC wire products are available?
We offer a wide range of CTC wire types including polyvinyl acetal enameled CTC with paper insulation, polyvinyl-adhesive acetal variants, polyesterimide enameled CTC, composite CTC with step or screen wire inside, and polyvinyl alcohol enameled CTC with PET film insulation, among others.
What is the recommended enamel insulation thickness for CTC wire?
The suggested enamel insulation thickness is 0.08–0.12mm. For bondable epoxy resin, the recommended thickness is 0.03–0.05mm.
Can you produce CTC wire with custom dimensions outside the standard range?
Yes. If your required dimensions fall outside the standard range listed, please contact us directly. We are able to provide tailored solutions based on specific project requirements.
How many insulation layers can be applied at one time during production?
Up to 24 insulation layers can be applied at one time. The maximum CTC bundle height is 80mm and maximum width is 26mm, both excluding paper insulation.
