Copper CTC (Continuous Transposed Conductor)
Introduction
Transposed cable, or Continuously Transposed Conductor (CTC), is one of the most widely used types of conductor for windings in power transformers. It consists of a group of enameled rectangular wires, typically coated with PVF (polyvinyl formal) enamel, that are transposed to create a rectangular strand.
In a CTC, each elementary conductor consecutively assumes every possible position inside the cable. The bundle of strips can then be wrapped and insulated with tapes, often using pure cellulose paper, providing high insulation and performance.
The transposition of the elementary conductors allows the creation of a highly flexible product, which adapts perfectly to transformer windings, significantly reducing electrical losses compared to a solid conductor with the same section. By adjusting the number of strips composing a CTC, various advantages can be gained for use in transformer applications.
Why Choose AKS Copper CTC
AKS International offers Copper CTC manufactured with precision and cutting-edge techniques to ensure exceptional conductivity and mechanical strength. Our Copper CTC provides optimal performance for transformer windings and electrical systems, helping reduce power losses and increase operational efficiency.
Advantages of Copper CTC
By increasing the number of strips in a CTC, the conductor's area is subdivided further compared to a single solid conductor. This leads to several benefits:
- Reduction of electrical losses.
- Increased flexibility, making it easier to wind into tight spaces.
- Optimized size of the winding for better utilization of space.
- Enhanced transformer efficiency and reduced manufacturing costs.
Insulation Options
CTCs can be insulated with a variety of materials, from pure cellulose kraft paper to high-performance insulators like thermo-stabilized paper, micro-crepe, polyester, and aramids, all of which support higher thermal classes. These insulation options ensure the Copper CTC can meet demanding operational conditions, such as high temperatures and electrical stresses.
