ABSTRACT:
A coupling transformer for networks with superimposed audio frequency voltage, especially for ripple control systems, with primary and secondary windings rigidly coupled with each other and arranged about an iron core; the primary and secondary windings surround one another coaxially and are separated and insulated from one another by a cast resin insulation, whereby only one of the two windings is embedded in the cast resin insulation while the other, freely accessible winding coaxially surrounds the iron core constructed as rod-type core under formation of at least one cooling channel; an electric shield is additionally provided between the two windings.
