Copper Conductors (CTC)

Product Introduction

Continuously transposed conductor (CTC) is a type of touched two lines winding wire which combined with certain number of rectangular enameled strips, request both upside and downside of two lines of enameled strips transposed as one direction, and continuously wrapped insulation paper, rope or belt.

Mainly have application in power transformer, traction transformer and reactor. The biggest characteristics of CTC is using hard wire or epoxy wire or both of these condition in a wire, this kind of wire have more mechanical strength, increase resistance to short-circuit for coil, able to keep coil power and voltage stable for long time and decrease whirlpool of winding and circulation current loss, compare with other copper wire. effectively improve useful rate of winding space, decreasesize of transformer, save transformer oil, improve winding efficiency
