China Continuously Transposed Conductor CTC- Self-adhesive Supplier, Service

It is mainly made of copper core, with a thermosetting self-adhesive coating added to the enameled layer, and is manufactured by transposition stranding and paper insulation wrapping. After the winding is wound and dried at high temperature, the self-adhesive layers are bonded and shaped with each other, and the conductor bundle forms an integral rigid structure, which greatly improves the short-circuit impact resistance and mechanical stability, without additional binding and the coil structure is more compact.

Frequently Asked Questions

What type of copper is used in the conductor?

The conductor utilizes high-purity Oxygen-free copper with a copper content of Cu ≥ 99.99%, ensuring excellent electrical conductivity and performance.

What materials make up the base insulation?

The base insulation consists of high-quality Polyvinyl acetal or Polyester-imide enamel, providing reliable electrical resistance and durability.

How does the self-bonding top layer function?

The outer layer features a specialized self-bonding resin coating. It is either thermosetting or heat-activated to securely bond the structure together under thermal processing.

Is this transposed conductor suitable for oil-immersed applications?

This specific self-bonding type does not use paper insulation, making it specifically designed for dry-type and non-oil applications.

What does "factory preformed transposition" mean?

It means the continuous and regular transposition process of the conductor strands is precisely executed at the factory level, ensuring optimal structural stability and performance.
