Abstract
Abstract A high power fluid cooled electric cable conduit is fixed in laterally offset axially overlapping relation to a fluid supply conduit with registering fluid passage ports in adjacent side walls thereof. The fluid supply conduit is closed at its overlapping end and an electric cable is introduced axially into the cable conduit through its overlapping end and in sealed relation therewith, the fluid supply ports being located between such overlapping ends of the conduits.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
60 words
A fluid cooled electric cable conduit assembly comprising a tubular conduit section having a lateral aperture adjacent one end, an electric cable extending axially through said conduit section in concentric annularly spaced relation, fluid sealing means between said cable and said conduit section at said one end thereof, and fluid supply means connected to supply cooling fluid through said aperture.
Claim 2
Dependent Claim
60 words
A fluid cooled electric cable conduit assembly comprising a tubular conduit section having a lateral aperture adjacent one end, an electric cable extending axially through said conduit section in concentric annularly spaced relation, fluid sealing means between said cable and said conduit section at said one end thereof, and fluid supply means connected to supply cooling fluid through said aperture.
Claim 3
Dependent Claim
62 words
A cable conduit assembly according to claim 1 wherein said fluid supply means comprises a second tubular conduit having one end fixed to said tubular conduit section in laterally offset axially overlapping relation and having a lateral aperture adjacent and in registry with the aperture in said tubular conduit section, and closure means at said one end of said second tubular conduit
Claim 4
Dependent Claim
26 words
A cable conduit assembly according to claim 2 wherein said electric cable extends along the outside of said second tubular conduit and is mechanically supported thereon.
Claim 5
Dependent Claim
100 words
A fluid conduit assembly comprising a pair of tubular conduit sections secured together in laterally offset axially overlapping relation, said conduit sections having fluid passage ports in registry in adjacent side walls thereof, closure means at the overlapped end of one said conduit section axially beyond said ports in one direction, an electric cable axially disposed in annular spaced relation in the other said conduit section, said cable entering said other conduit section axially through the overlapped end thereof, and fluid sealing means between said cable and said other conduit section disposed axially beyond said ports in the other direction.
Claim 6
Dependent Claim
100 words
A fluid conduit assembly comprising a pair of tubular conduit sections secured together in laterally offset axially overlapping relation, said conduit sections having fluid passage ports in registry in adjacent side walls thereof, closure means at the overlapped end of one said conduit section axially beyond said ports in one direction, an electric cable axially disposed in annular spaced relation in the other said conduit section, said cable entering said other conduit section axially through the overlapped end thereof, and fluid sealing means between said cable and said other conduit section disposed axially beyond said ports in the other direction.
Claim 7
Dependent Claim
22 words
A fluid conduit assembly according to claim 4 including a tubular metallic sheath encasing said electric cable adjacent said fluid passage ports.
Claim 8
Dependent Claim
30 words
A fluid conduit assembly according to claim 4 wherein said fluid sealing means includes a tubular clamping sleeve encasing said electric cable in the region adjacent said fluid passage ports.
Claim 9
Dependent Claim
142 words
A high power fluid cooled electric cable conduit assembly comprising a first tubular conduit section having a fluid entry port in a side wall thereof adjacent one end, a second tubular conduit section of insulating material coupled to the other end of said first section in axial alignment therewith, and insulated electric cable entering said one end of said first conduit section and traversing both said sections in axially aligned annularly spaced relation therewith, sealed bushing means between said cable and said first conduit section, and a fluid supply conduit fixed to said first tubular conduit section in overlapping relation with said one end thereof and extending in laterally offset parallel relation thereto, said fluid supply conduit having a lateral fluid supply port in registry with said entry port thereby to supply cooling fluid between said cable and said tubular conduit sections.
Claim 10
Dependent Claim
142 words
A high power fluid cooled electric cable conduit assembly comprising a first tubular conduit section having a fluid entry port in a side wall thereof adjacent one end, a second tubular conduit section of insulating material coupled to the other end of said first section in axial alignment therewith, and insulated electric cable entering said one end of said first conduit section and traversing both said sections in axially aligned annularly spaced relation therewith, sealed bushing means between said cable and said first conduit section, and a fluid supply conduit fixed to said first tubular conduit section in overlapping relation with said one end thereof and extending in laterally offset parallel relation thereto, said fluid supply conduit having a lateral fluid supply port in registry with said entry port thereby to supply cooling fluid between said cable and said tubular conduit sections.
