Wound transformer cores are manufactured in process of winding up the transformer strip on a mandrel followed by the processes of cutting the hot-manufactured and synthetic resin-bond core. Wound cores shape is better adapted for course of the magnetic induction current and the structure of material grain is used more effectively when compared with cores composed of sheet stampings of various shapes.

Cut cores are assembled with a certain air-gap between the pieces, insulation pieces are placed in these gaps during the assembly of the bobbins. Cut surfaces of these cores can be round, oval and rectangular.

BENEFITS OF CUT C CORES

▪ Electrical energy saving thanks to low specific iron watt losses
▪ Saving in quantity of used copper for winding thanks to smaller dimensions and weight of cut cores
▪ Saving in work costs exert for transformers assembly thanks to easy assembly
▪ Low humming

STEPPED CROSS-SECTION CORES
 Shape of stepped cross-section cores allows better flow of magnetic flux density and their special grain structure is used more effectively as compared with cores composed of metal sheet stampings of various shapes. Specific intersection of these cores allows varied use of circular coils.As a result of considerable variety of demands on construction we do not provide any standardized assortment. Stepped cross-section cores are manufactured with two or three steps according to customer’s specification.

BENEFITS OF STEPPED CROSS-SECTION CORES

▪ Electrical energy saving thanks to low specific iron watt losses
▪ Saving in quantity of used copper for winding thanks to smaller dimensions and weight of cut cores
▪ Saving in work costs exert for transformers assembly thanks to easy assembly
▪ Low humming
▪ Better use of coils scope due to stepped cross-section
▪ Easier winding of wire on a circular coil
