Connection equipment for medium voltage containing bus bars 10 with circular circumferences, which are single-phase, enclosed in a tubular casing 20 of insulation material with air insulation between the bus bar and the casing. The bus bar 10 is centred by insulated supports 23, with a creep distance which is larger than the airspace between the bus bar and the surrounding insulation and is placed at an axial distance a from the fixing 21 of the casing in, for example, a cell wall 30. The cable connection to the bus bar is carried out through an insulated tube 22 arranged perpendicular to the casing tube. The equipment has a modular construction. <IMAGE> |
