Abstract

The invention is related to a transformer/reactor for high voltage comprising at least one winding. The invention is characterized by the winding being provided by means of an insulated electric conductor (60) comprising at least a current-carrying conductor (61) and furthermore comprising a first layer (62) having semiconducting properties arranged around the current-carrying conductor, a solid insulation layer (63) arranged around said first layer, and a second layer (64) having semiconducting properties arranged around the insulation layer, and furthermore that at least a part of the winding is embedded in a casting material. The invention in addition relates to a method for manufacturing such a transformer/reactor, and to a pre-manufactured winding module.
