The air or gas is distributed to the respective cubicles (1a-1d) in the series of cubicles via channels (5,6a-6d) in the form of protective channels or busbar boxes which constitute semiprotection for the single-phase or multi-phase busbars (4a-4d) which distribute electric current to the cubicles and to the electric equipment present in the cubicles. The cubicles. The direction of the cooling gas distribution is the same as the current direction or reversed relative thereto.
