Abstract
A transformer or reactor magnetic core 1 is wound with an insulating electric conductor 2 including at least one current carrying conductor, a first layer having semiconducting properties arranged to surround the conductor, a solid insulation layer arranged to surround said first layer, and a second layer having semiconducting properties arranged to surround the insulating layer. A regulating winding 3 is arranged around a magnetic flux carrier core 1, and the conductor of the regulating winding can be wound on or off the core from winding drum 12 to vary the length of said regulating winding around the magnetic flux core and thereby regulate the induced voltage in the transformer or the reactive power of the reactor.
