Claims

[Claims for Utility Model Registration] (1) In a gas-insulated switchgear in which two sets of cable heads each for three phases are connected to a common conductor via a predetermined device, the two sets of cable heads are Supported on a plate that closes one end in the axial direction of a common container, with each axis parallel to the axis of the container, and arranged in a row on both sides of a plane containing the central axis of the container. and the devices respectively connected to the two sets of cable heads are housed in the container together with the two sets of cable heads and arranged on both sides of the plane, and the common conductor connects the other end of the container in the axial direction. A gas insulated switchgear characterized in that the gas insulated switchgear is connected to a through conductor of an insulating spacer that is attached to close. (2) The gas insulated switchgear according to claim 1, wherein the container is formed to have an oval or oval cross section, and the plane is a plane along the longitudinal direction of the cross section of the container. (3) The gas insulated switchgear according to claim 1 or 2, wherein the equipment provided between the cable head of each set and the common conductor is a disconnector and a grounding switch. (4) A device installed between one set of cable heads and a common conductor is a disconnect switch, and a device installed between another set of cable heads and a common conductor is a disconnect switch. The gas insulated switchgear according to claim 1 or 2, wherein the gas insulated switchgear is a connecting conductor for connecting.
