Product Description

Transposed conductor refers to the combination of a number of enameled copper flat wires into two rows with wide surfaces in contact with each other, and according to the requirements on the top and bottom of the two rows of enameled wires along the narrow side of the same direction of transposition, and electrical insulation tape is used. As a multi-layer continuous and tightly wrapped composition

The windings of large power transformers use transposed conductors, which can greatly reduce load loss, reduce the temperature rise of winding hot spots, improve the mechanical strength of windings, make the structure more compact, and make coil processing easier. It is widely used in winding design and manufacture.
