What is Continuously Transposed Conductor?
Continuously transposed conductors CTC Cable is made of a certain number of enameled flat wires arranged in two columns in sequence by special technology, and wrapped by special insulating materials( insulation paper, rope or tape). It consists of a group of enameled rectangular wires, usually with PVF (polyvinylformal) enamel, which are transposed to create a kind of rectangular strand. In the CTC, each elementary conductor consecutively and repeatedly assumes every possible position inside the cable. The bundle of strips can be wrapped and insulated with tapes, generally in pure cellulose paper. CTC configurations come in different lengths to best suit the diameter of transformer windings for different applications and they may also contain between five and 73 wire strands. The finished product is used in power transformers as winding wires. CTC Conductor is mainly used in medium and ultra-high power transformers in electrical equipment. （large-scale oil-immersed power transformers, reactors and large-capacity dry type transformers. ）
