Product Introduction

Transposition wire is a winding wire made by arranging a certain number of enameled flat wires in two columns in a special process and continuously weaving them, and wrapping them with specific insulation materials. Mainly used for manufacturing windings of large oil immersed power transformers, reactors, and large capacity dry-type transformers. The use of transposed wires to manufacture transformers increases the space utilization of windings, reduces volume and costs, and lowers the additional losses caused by circulating currents and eddy currents due to leakage magnetic fields. At the same time, it also increases the mechanical strength of the winding and saves winding time. Continuous transposition wire is a material required for manufacturing transformer windings. It has high space utilization, good heat dissipation performance, low eddy current loss, high mechanical strength, less coil winding time, and good process performance.
