Product Description
Aluminium Continuously Transposed Conductors (CTCs) are engineered for use as winding materials in power distribution, traction, and furnace transformers. The continuous transposition of aluminium strands enables balanced electromagnetic performance and efficient heat dissipation, making aluminium CTCs well suited for high-efficiency transformer windings, particularly where weight reduction and cost efficiency are key design considerations.
Key Advantages
- Reduced eddy current and circulating losses
- Uniform current distribution across strands
- Improved thermal performance and lower hot-spot temperatures
- Lightweight conductor solution compared to copper
- High mechanical stability during winding
- Enhanced transformer efficiency and service life
Available Variants
- Continuously Transposed Conductor (Standard CTC) Designed for optimal electrical and thermal performance in transformer windings using aluminium strands.
- Twin CTC Suitable for higher current ratings and compact winding designs where aluminium is preferred.
- Special Protection Paper-Covered CTC Provides enhanced insulation and protection for demanding operating conditions.
- Netting Tape CTC Offers additional mechanical strength and improved handling during winding.
Applications
- Power distribution transformers
- Traction transformers
- Furnace transformers
- Other heavy electrical equipment requiring high-efficiency aluminium windings
