Frequently Asked Questions (FAQ)
Q
What is the maximum number of strips available for CTC cables?
CTC cables are available with 5 to 80 strips, supporting both odd and even strip counts to accommodate a wide range of transformer winding requirements.
Q
What conductor dimensions are supported for single conductors?
Single conductor thickness (a) ranges from 0.90mm to 3.15mm (tolerance ±0.01mm), and width (b) ranges from 2.50mm to 13.00mm (tolerance ±0.01mm). The suggested width-to-thickness ratio is 2.0 < b/a < 9.0.
Q
What types of insulation are available for CTC products?
Various insulation types are available, including paper insulation, PET film insulation, polyvinyl acetal enamel, polyesterimide enamel, and bondable epoxy resin. Different product variants combine these insulation systems to meet specific application needs.
Q
What is the maximum overall dimension of the CTC bundle?
The maximum height of CTC bundles is 80mm (excluding paper insulation) and the maximum width is 26mm (excluding paper insulation). The overall max height including manufacturing tolerances is 120mm.
Q
Can custom dimensions outside the standard range be produced?
Yes. If your required dimensions fall outside the standard production range, please contact us directly. Our engineering team can evaluate custom specifications and provide tailored solutions for special project requirements.
Q
What applications are CTC (Continuously Transposed Conductor) cables suitable for?
CTC cables are primarily used in high-performance power transformers, including large power transformers and special industrial transformers. The transposed structure significantly reduces eddy current losses and enhances overall electrical efficiency and thermal performance.
