Abstract
A gas insulated switching apparatus has lightning arrestors in a line side unit. Each lightning arrestor is mounted to be moved linearly into and out of connection with a corresponding conductor. Specifically, the cover which supports the lightning arrestor is disposed beneath the bottom plate of the vessel of the line side unit. The lightning arrestors are connected to a monitor of an operating device beneath the line side unit. Since the lower portion of the lightning arrestors are connected to the monitor, the length of the connection lines is made sufficiently short.
