Conductors, Core & Magnetic Steel
Standards: IEC 60404 (grain-oriented electrical steel)
CRGO laminations, copper and CTC (continuously transposed) conductors, foil windings and core-building materials.
CTC (Continuously Transposed Conductor)
Multi-strand transposed copper for low-loss large windings.
Paper-Covered Copper/Aluminium
Round and rectangular covered conductor for windings.
CRGO Electrical Steel
Grain-oriented core steel — M4 to laser-scribed Hi-B grades.
Amorphous Ribbon
Ultra-low-loss core material for distribution transformers.
Frequently asked
A bundle of individually insulated rectangular strands that are continuously transposed so each occupies every radial position, minimising eddy and circulating losses.
CRGO has strongly anisotropic magnetic properties along the rolling direction, giving low loss and high permeability for the core.
In a large winding, strands see different leakage flux; transposing equalises the induced EMF and evens current sharing, cutting stray (eddy) losses.
