PROBLEM TO BE SOLVED: To provide a gas insulation switchgear capable of suppressing a height dimension of a switchgear.SOLUTION: The switchgear accommodates at least a breaker 23a, a disconnector 24a and a main circuit conductor 60 connecting the breaker and the disconnector within a tank 44 and comprises a cable termination connection part 100 for connecting the main circuit conductor 60 and an external cable 110. Between the cable termination connection part 100 and the breaker 23a, the disconnector 24a is disposed in the state where its movable contactor is electrically connected with the cable termination connection part 100 at all the time. The cable termination connection part 100 includes: a first connection part A that is connected with the cable 110; a disconnection part which disconnects the main circuit conductor 60 and the first connection part A; and a second connection part B which is provided closer to the first connection part A than the disconnection part, and is connected to the main circuit conductor 60.SELECTED DRAWING: Figure 1 【課題】スイッチギヤの高さ寸法を抑えることができるガス絶縁スイッチギヤを得る。【解決手段】 タンク４４内に少なくとも遮断器２３ａと断路器２４ａとこれらを接続する主回路導体６０とを収納し、前記主回路導体６０と外部のケーブル１１０との間を接続するケーブル終端接続部１００を備えたスイッチギヤにおいて、前記ケーブル終端接続部１００と前記遮断器２３ａとの間に，その可動接触子が前記ケーブル終端接続部１００と常時電気的に接続した状態に断路器２４ａを配置し、前記ケーブル終端接続部１００は、前記ケーブル１１０と接続する第１の接続部Ａと、前記主回路導体６０と前記第１の接続部Ａとの間を切離する断路部と、前記断路部よりも前記第１の接続部Ａ側に設けられた第２の接続部Ｂとを備えて、前記主回路導体６０に接続される。【選択図】図１
