PROBLEM TO BE SOLVED: To obtain a gas insulated switch gear that facilitates inventory control in factory by reducing the number of types of bus bars and that is able to easily cope with user's urgent request for bus bar replacement.SOLUTION: In a gas insulation switch gear, tanks 44 accommodating switching devices, such as a breaker 23a and a disconnecting device 24a, with insulating gas sealed therein are arranged in parallel in a horizontal direction, and a horizontal bus bar extends in the direction of parallel arrangement. The gas insulation switch gear comprises: a bus-bar connection device 120(Y) electrically connecting horizontal bus bars K, L, M composed of a unit bus bar 128 of tank width unit length; and a bus bar support device 140(X) attached to a tank wall, thereby connecting or supporting the horizontal bus bars K, L, M. At least both ends of each of the horizontal bus bars K, L, M are connected to a bus bar connection device 120(X). If both the ends are arranged over three or more of the tanks, the horizontal bus bar is supported by the bus-bar support device 140 or bus-bar connection device 120 for each intermediate tank.SELECTED DRAWING: Figure 5 【課題】母線の種類を少なくして工場の在庫管理を容易にし、ユーザにおいて緊急に母線交換の必要が生じても容易に対応できるガス絶縁スイッチギヤを得る。【解決手段】遮断器２３ａや断路器２４ａ等の開閉機器を絶縁性ガスを封入したタンク４４に収容してタンクを横方向に複数個並置し、並置方向に水平母線を延在配置したガス絶縁スイッチギヤにおいて、タンク幅単位の長さの単位母線１２８で構成された水平母線Ｋ、Ｌ、Ｍ、とタンク内機器との間を電気的に接続する母線接続装置１２０（Ｙ）と、タンク壁に装着されて水平母線Ｋ、Ｌ、Ｍ、を接続・支持する母線支持装置１４０（Ｘ）とを備え、水平母線Ｋ、Ｌ、Ｍ、の少なくとも両端部は母線接続装置１２０（Ｘ）に接続し、３個以上のタンク間をまたいで配置する場合には中間のタンク毎に水平母線を母線支持装置１４０あるいは母線接続装置１２０で支持する。【選択図】図５
