ABSTRACT:
An insert for a hydro pole switch is disclosed. The insert has a rod member extending the length of a hydro pole and terminating at a handle.

The insert has an element formed from electrically insulating material having a first flange mounted on each end thereof; a pair of coupling members are provided for engagement with the first flanges and each are attachable with a corresponding end portion, whereby the insert enables the handle to be electrically isolated from its associated switchgear in a simple and economic manner.
