Amendment April 19, 1980 The scope of claims for utility model registration is amended as follows.

[Scope of Claim for Utility Model Registration] (1) In a three-phase integrated gas-insulated electric device in which a disconnector, lightning arrester, instrument transformer, and earthing switch are connected to the terminal of a power cable, a branch pipe is formed on the side wall. a sealed container, a terminal portion of the power cable housed in the sealed container, the lightning arrester placed between the terminal portions and housed in the sealed container, and placed near an extension of the central axis of the terminal portion . the instrument transformer, which is housed in the sealed container;
A gas characterized by comprising: the disconnector housed in the sealed container across the branch pipe; and the earthing switch placed near the axial extension of the disconnector and housed in the sealed container. Insulated electrical equipment. (2) A sealed container with lids attached to the upper and lower openings, and a terminal portion fixed to the lower lids.
A gas insulated electrical device according to claim 1, which is a registered utility model, comprising: a lightning arrester; and an instrument transformer fixed to the upper lid. The brief description of the drawing has been amended as follows. "Terminal insulated conductor" on page 7, line 20 of the specification is corrected to "terminal section."
