Class 180/200 Aramid Paper-Insulated Copper Continuously Transposed Conductor
PRODUCT DESCRIPTION
Class 180/200 Aramid Paper-Insulated Copper Continuously Transposed Conductor combines high-conductivity rectangular copper strands with high-performance aramid paper insulation. Multiple individually insulated strands are continuously transposed to form a compact conductor suitable for high-performance transformer windings.
The aramid paper insulation system provides excellent thermal capability, dielectric performance, mechanical strength, and compatibility with demanding transformer insulation systems. The product is suitable for high-power transformers and applications where enhanced thermal and mechanical performance is required.

Q&A
Q: What is the main advantage of aramid paper insulation?
A: Aramid paper provides high thermal capability, good dielectric performance, and strong mechanical properties for demanding transformer insulation systems.
Q: What is the difference between Class 180 and Class 200?
A: They represent different thermal-performance levels of the insulation system. The appropriate grade can be selected according to the transformer design and required operating temperature.
Q: Is this CTC suitable for oil-immersed transformers?
A: Yes. It can be designed for compatible oil-immersed transformer insulation systems.
Q: Can the aramid paper thickness be customized?
A: Yes. Paper type, number of layers, insulation thickness, and application method can be specified according to the customer's requirements.
Q: Can this product be manufactured for large transformer windings?
A: Yes. Strand count, dimensions, transposition pitch, insulation construction, and coil length can all be customized for large transformer designs.
Q: Why use CTC instead of a conventional rectangular conductor?
A: CTC distributes the current among multiple transposed strands and can reduce additional losses while providing a compact conductor configuration for transformer windings.
