SB-ECTC, Self-Bonding Acetal Enamelled Copper Continuously Transposed Conductor, High Conductivity Enameled Rectangular Copper CTC Wire

Self-Bonding Acetal Enamelled Copper Continuously Transposed Conductor

PRODUCT DESCRIPTION

Self-Bonding Acetal Enamelled Copper Continuously Transposed Conductor combines individually enamelled rectangular copper strands with an additional bonding layer. After winding and appropriate heat or other specified activation, the bonding layer helps the conductor strands form a mechanically stable structure.

The construction provides reliable electrical insulation while improving winding integrity, dimensional stability, and resistance to mechanical movement. It is designed for demanding transformer winding applications where conductor stability and compact winding construction are important.

Q&A

Q: What makes this CTC self-bonding?
A: An additional bonding coating allows adjacent strands to form a mechanically stable structure after the specified activation process.

Q: Why use self-bonding CTC?
A: It can improve winding stability, reduce strand movement, and help maintain a compact conductor structure during transformer operation.

Q: Can the bonding activation method be customized?
A: Yes. The bonding system can be selected according to the customer's winding process and thermal requirements.

Q: Is the conductor suitable for large transformers?
A: Yes. Its construction can be customized for high-current and large transformer winding applications.

Q: Can different strand configurations be supplied?
A: Yes. Strand count, dimensions, insulation system, and transposition pitch can be customized.
