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

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.

CTC Manufacturing Process

Two type manufacturing process: 

1. 4-49 flat enameled copper or aluminum wire with paper covered
2. 4-49 flat enameled copper or aluminum wire with cotton wire

Application


Enamelled wire is used in many electrical products, usually for the purpose to generate electrical fields such as in transformers and motors. Special examples are voice coils made from selfbonding wire or enamelled aluminum wire for instance or injection valves made of enamelled brass wire.
