Product Description

GRM Rolling Mill’s CTC Continuously Transposed Conductor Line continuously transposes from 5 up to 47 strands by coating cold-worked, oxygen-free flat copper wires with insulating varnish and wrapping them with insulating paper and other insulation materials. The conductors are then stranded into a compact and neatly arranged rectangular cross-section conductor bundle.

FAQ

1. What is a CTC conductor?

CTC (Continuously Transposed Conductor) is a rectangular conductor bundle made by continuously transposing multiple insulated flat conductors to reduce eddy current losses in transformers.

2. What materials can the line process?

The line is mainly designed for enamel-coated oxygen-free flat copper conductors and related magnet wire materials.

3. Can the machine be customized?

Yes. GRM provides customized configurations according to conductor dimensions, production speed, insulation structure, and plant layout.
