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.
