Details

Overview


Continuously transposed cable (CTC) is a type of winding wires weaved by certain number of strips of enameled rectangular wires in two ranks according to special tectonics and wrapped by special insulation material. It is mainly used for large-scale oil-immersed power transformers, reactors and large-capacity dry type transformers.

Product Description


Polyvinyl acetal enameled with paper insulation CTC

Continuously transposed cable (CTC) is a type of winding wires weaved by certain number of strips of enameled rectangular wires in two ranks according to special tectonics and wrapped by special insulation material. It is mainly used for large-scale oil-immersed power transformers, reactors and large-capacity dry type transformers.

CTC conductor can improve using rate of winding space, min-ish volume and reduce cost, most of all, it decline the loss of circumference and eddy loss caused by leaking of magnetic field and also has advantages of improving machine strength of winding and saving winding time.

number of strips: 7-49
single dimension: thickness of conductor a : 1.00-3.15mm width of conductor b : 3.00-12.50mm
suggested ratio of width and thickness: 2.5 < b/a <7.5
please connect us if your dimension is out of above range Insulation layers: 24
layers at one time. Max thickness of CTC: 80mm (excluding insulation)
max width: 26mm (excluding insulation)
Max.Height of CTC bundles: 80mm (excluding paper insulation)
Max. Width of CTC bundles: 26mm (excluding paper insulation)
