ABSTRACT:
Electrical equipment cell of the air insulated type, comprising a switch which connects a first plug which is live, to a second plug, on either side of a wall, the switch being arranged in an assembly formed by a metallic tank fixed on the wall and by two bell-shaped insulators which are assembled on the metallic tank to receive the first and second plugs respectively. A dielectric screen connected to ground is placed in the first bell-shaped insulator between the contacts of the switch in the open position, so the, in that open position, a person placed on the same side as the second bell-shaped insulator cannot come directly into contact with a live part.
