Ferroxcube UR cores

 Ferroxcube core UR

Ferroxcube UR Cores can be applied as analogs of russian-manufactured configurations ПK, ППK and ПКК for producing of power high-voltage transformers with a quality decoupling between windings. Ferroxcube produces ferrite cores UR on the base of power materials 3C90, 3C94.

The figure presents several standart types of Ferroxcube UR cores:Type1 - analog of russian-manufactured cores ПКК, Type 2 - analog of russian-manufactured cores ПК, Type 4 - analog of russian-manufactured cores ПКК.

Geometrical dimensions and cores features are listed in pdf-document and in the table below.
