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.
Enameled Flat wire is made of oxygen free copper or electrical aluminum rod, which are drawn or extruded by the specification mould.They are mainly used in the windings of electrical equipment such as transformer,reactor and et cetera.According to the different insulating paint, it can be divided into 6 categories:
