Abstract: A unique design and method of construction is presented for a spacer and support suitable for use in maintaining one or more electrical conductors at a fixed distance from one another while permitting dielectric fluid to flow therebetween. The spacer is formed from two major parts: a foraminous container and a void filling means. The foraminous container defines a plurality of flow apertures around its periphery, and at either end, into which dielectric fluid is free to flow. The container is filled with a void filling means formed from a plurality of generally incompressible filler elements or nodules. The filler elements are packed into the container so as to maintain the correct spacing. The nodules or filler elements are sufficiently large that they remain confined within the container. Dielectric fluid fills the interstices between the void filling means and the container walls.

Abstract: A conductor support is provided for use with high voltage electrical devices having mounting walls with apertures formed therein through which electrical conductors pass. The conductor support is formed of first and second channel members sequentially inserted in the mounting wall aperture. The first channel member includes walls bendable toward and away from each other, corresponding to collapsed and expanded configurations of the first channel member, respectively. The first channel member is collapsed to take on a reduced cross sectional area, and is inserted through the aperture of the mounting wall. The first channel member includes retaining members, such as notches or grooves, for engaging the mounting wall. After insertion, the first channel member is expanded to bring the retaining members into engagement with the mounting wall.
