Abstract

A gas insulated switchgear includes a bus unit, a breaker unit and a line side unit. An insulating spacer structure attaching at least two of the units together includes an inner flange on a first unit, an outer flange on a second unit, and an insulating spacer positioned between the first and second units. Closed end tapped holes are formed in the inner flange and idle holes are formed in the outer flange, and tapped holes with a larger diameter than that of the tapped holes of the inner flange are formed in the insulating spacer.
