Product Introduction
Transposed Conductor is an important material for making transformer winding. it has the advantages ofhigh space utilization, low eddy current loss, high mechanical strength and less winding time. it is mainlyused to manufacture windings of power transformers, reactors and traction transformers.
Spenser specializes in producing copper and aluminum conductortransposition wires with accurate dimensions, short transposition pitchmoderate wrapping tightness, and continuous joint-free length of morethan 3500 meters.
