PCT No. PCT/SE90/00468 Sec. 371 Date Jan. 22, 1992 Sec. 102(e) Date Jan. 22, 1992 PCT Filed Jun. 29, 1990 PCT Pub. No. WO91/03087 PCT Pub. Date Mar. 7, 1991.The invention relates to a new arrangement of at least one valve stack (2) for high voltage direct current in a valve hall (1). Said valve stack (2) has a voltage to ground which, in operation, increases along the stack (2). The invention comprises arranging the stack (2) in a substantially lying position at such a distance from the floor and roof (9), respectively, of the valve hall (1) that the smallest electrical flashover distance between live parts on the stack (2) and said floor and roof (9), respectively, is at least contained. Further, the electrical connection is arranged via bushings through the roof (9) of the valve hall (1).
