摘要： A three-pole cable connecting unit for a compressed gas-insulated high-voltage switching installation is disclosed having three cable connecting elements, a three-pole isolating switch and (optionally) a three-pole ground mechanism, as well as two three-phase conductor branches, all lying encapsulated within a housing. To make the housing as small as possible, the three cable connecting elements are introduced into the receptacle at the end wall in a generally parallel fashion to connect with the fixed contacts of the isolating switch. The isolating switch is generally arranged in a plane which lies at right angles to the diametrical longitudinal plane of the housing. The isolating gaps of the switch are inclined toward each other. From the contacts of the isolating switch, connecting conductors fan out toward a conductor branch at the housing side in such a way that they lie at the tips of an equilateral triangle. Likewise, other connecting conductors fan out toward a second conductor branch at the housing end wall where they also lie at the tips of an equilateral triangle. The actuation of the contact pins of the isolator switch occurs from a drive shaft arranged parallel to the diametrical longitudinal plane in the manner of a chord.
