Heat-Resistant Self-Bonding Copper Continuously Transposed Conductor (CTC), Thermally Stable Winding Conductor for High-Temp, Furnace, Traction & Power Transformers, IEC 60317 Compliant
Heat-Resistant Self-Bonding Copper Continuously Transposed Conductor
PRODUCT DESCRIPTION
Heat-Resistant Self-Bonding Copper Continuously Transposed Conductor is engineered for transformer windings requiring enhanced thermal performance and reliable mechanical stability. Multiple rectangular copper strands are individually enamel insulated and continuously transposed, with a heat-resistant self-bonding system applied to provide structural integrity.
The combination of high-conductivity copper, high-temperature insulation, and self-bonding technology makes this CTC suitable for demanding transformer winding environments where thermal endurance, dimensional stability, and electrical reliability are essential.
