Abstract
A line guard is configured so as to have a very large air gap with a small overall physical size of the device. Opposed interleaved sets of plural insulating leaves are formed along a discontinuity extending along the length of the line guard so as to greatly extend the length of the air gap. This air gap structure allows the overall size of the line guard to be small thus providing advantages of reduced weight, ease of handling, and ease of storage. A two piece coupler apparatus is provided for joining adjacent line guards in a way that is both flexible and provides sufficient dielectric to operate at high voltages in a small package.
