Claims

[Scope of utility model registration request]

Three-phase conductors are insulated and supported in a conduit filled with insulating gas, and the central axes of two of the phase conductors are placed on a horizontal plane that includes the central axis of the conduit, and the remaining one-phase conductor is placed on a horizontal plane that includes the central axis of the conduit. In a gas-insulated three-phase collective busbar with the central axis of A gas-insulated three-phase collective bus bar characterized in that the conductors of each phase are arranged so that the distance between the conductor and the inner surface of the conduit is greater than the distance between the conductor and the inner surface of the conduit.
