Continuously transposed conductors (CTC) are used in medium and ultra-high power transformers.
Enameled wires with PVF, EIW, or EI/AIW and insulated with insulation paper can be used for large oil-immersed power transformer, reactor, large capacity dry type transformers.
Shorten winding time for the coil of transformer.
Decrease size and weight of the transformer and reduce the cost. Reduce eddy and circulating current losses.
Excellent winding performance and simplified winding processing. Improve mechanical strength of winding. (Hardened self-bonding CTC).
Concentrically enameled: Insulation increase 0.05+/-0.01 mm
Low chip: Insulation increase
Width: 0-0.03 mm
Thickness: 0.03+/-0.01 mm
Strand dimensions | Range | Min Pitch | Standard |
Thickness | 1.00---3.15 | 35mm | 5-87 strips |
Width | 3.00---12.50 |
A coating of epoxy resin can be applied to increase mechanical strength, improve short circuit resistance. High bond strength minimum 7 MPa.
Excellent temperature resistance. Smooth surface.
Long shelf life in B-stage.
