Abstract
Abstract Tubular enclosure for a high voltage conductor: the enclosure comprises a nonconductive glass reinforced plastic material pipe which serves as the gas pressure vessel for a dielectric gas within the pipe; a wound conductive foil electric ground shield is incorporated into the nonconductive layer. The joint between adjacent housing lengths is sealed with a conductive epoxy; a means on the interior of the joint prevents the bonding adhesive from penetrating inside the housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
165 words
A joint between sections of a tubular enclosure for a conductor, wherein a conductor is within and spaced away from the interiors of said sections of said enclosure; each said section of tubular enclosure comprising: a layer of nonconductive material, which defines the shape of said enclosure and serves as a support for a conductive material layer; said nonconductive material layer having an exterior and having an interior, the latter facing inward to the conductor; a conductive material layer being supported on said noncOnductive material layer and being positioned interiorly from said nonconductive material layer exterior; each said enclosure section having an end which faces toward a said end of the other said section; disposed between said facing ends is a conductive adhesive material which electrically connects the said conductive layers in each said enclosure section and seals the joint between said sections; said facing ends being slanted obliquely to the longitudinal axis of the enclosure at a corresponding angle so that the ends mate.
Claim 2
Dependent Claim
165 words
A joint between sections of a tubular enclosure for a conductor, wherein a conductor is within and spaced away from the interiors of said sections of said enclosure; each said section of tubular enclosure comprising: a layer of nonconductive material, which defines the shape of said enclosure and serves as a support for a conductive material layer; said nonconductive material layer having an exterior and having an interior, the latter facing inward to the conductor; a conductive material layer being supported on said noncOnductive material layer and being positioned interiorly from said nonconductive material layer exterior; each said enclosure section having an end which faces toward a said end of the other said section; disposed between said facing ends is a conductive adhesive material which electrically connects the said conductive layers in each said enclosure section and seals the joint between said sections; said facing ends being slanted obliquely to the longitudinal axis of the enclosure at a corresponding angle so that the ends mate.
Claim 3
Dependent Claim
171 words
A joint between sections of a tubular enclosure for a conductor, wherein a conductor is within and spaced away from the interiors of said sections of said enclosure; each said section of tubular enclosure comprising: a layer of nonconductive material, which defines the shape of said enclosure and serves as a support for a conductive material layer; said nonconductive material layer having an exterior and having an interior, the latter facing inward to the conductor; a conductive material layer being supported on said nonconductive material layer and being positioned interiorly from said nonconductive material layer exterior; each said enclosure section having an end which faces toward a said end of the other said section; disposed between said facing ends is a conductive adhesive material which electrically connects the said conductive layers in each said enclosure section and seals the joint between said sections; said conductive adhesive material having plasticity sufficient to enable it to change shape due to variations of temperature and the presence or absence of current in the conductor.
Claim 4
Dependent Claim
171 words
