Abstract

A transformer/reactor and a method of manufacturing a transformer/reactor comprising a laminated core (1, 11, 111) and at least one winding for high voltage, each winding comprising a high-voltage cable (6) with means for enclosing an electric field, which high-voltage cable (6) is magnetically permeable and the core (11, 111) being provided with cooling flanges (33, 133).
