💬 Frequently Asked Questions
Q What is the maximum number of CTC strips that can be produced?
The production scope supports CTC strips ranging from 5 to 80 (odd or even), providing flexible options for various transformer winding requirements.
Q What are the dimensional tolerances for CTC conductor wires?
The single conductor thickness (a) ranges from 0.90–3.15mm with a tolerance of ±0.01mm, and the width (b) ranges from 2.50–13.00mm with the same tolerance of ±0.01mm. Overall CTC dimensions have a tolerance of ±0.05mm.
Q What insulation types are available for CTC products?
Multiple insulation options are available, including paper insulation, PET film insulation, bondable epoxy resin, and special binded types. Enamel insulation thickness is typically 0.08–0.12mm, while bondable epoxy resin thickness is 0.03–0.05mm.
Q What is the suggested width-to-thickness ratio for CTC conductors?
For the production scope, the suggested ratio is 2.0 < b/a < 9.0. For the product description specifications, the suggested ratio is 2.5 < b/a < 7.5. If your dimensions fall outside these ranges, please contact us directly.
Q What CTC product types do you offer?
We offer a comprehensive range including Polyvinyl acetal enameled CTC with paper insulation, Polyesterimide enameled CTC, Composite CTC with step or screen wire inside, and Polyvinyl alcohol enameled CTC with PET film insulation, among others.
Q What are the maximum bundle dimensions for CTC products?
The maximum height of CTC bundles is 80mm and the maximum width is 26mm, both measurements excluding paper insulation. Up to 24 insulation layers can be applied at one time.
