Abstract (en)
[origin: EP0918341A2] An electric transformer for high- and very high-intensity currents, particularly for furnaces and rectifiers, comprising a tank (2) which contains a magnetic core (3) with the corresponding windings (4,5). The low-voltage feedthroughs for high- and very high-intensity currents protrude hermetically from the tank (2). The particularity of the invention is constituted by the fact that at least the portion of the wall of the tank that is affected by the low-voltage feedthroughs is made of aluminum and/or alloys thereof and forms openings for the hermetic passage of the low-voltage feedthroughs. <IMAGE>
