Independent Claim
127 words
An electrical penetration assembly for a containment vessel comprising: an elongated hollow penetration nozzle sealed in a wall of said vessel to provide a passage therethrough; an apertured header sealed to one end of said nozzle; at least one module sealed in an aperture in said header, said module comprising an elongated hollow body, said body having a length less than the length of said nozzle, said module being supported solely by said header; at least one electrical conductor extending through said body; means providing a vapor and pressure seal between said conductor and each end of said body and providing a chamber within said body intermediate of said ends; and means communicating with said chamber for pressurizing said chamber to test the integrity of said seals.
Claim 2
Dependent Claim
127 words
An electrical penetration assembly for a containment vessel comprising: an elongated hollow penetration nozzle sealed in a wall of said vessel to provide a passage therethrough; an apertured header sealed to one end of said nozzle; at least one module sealed in an aperture in said header, said module comprising an elongated hollow body, said body having a length less than the length of said nozzle, said module being supported solely by said header; at least one electrical conductor extending through said body; means providing a vapor and pressure seal between said conductor and each end of said body and providing a chamber within said body intermediate of said ends; and means communicating with said chamber for pressurizing said chamber to test the integrity of said seals.
Claim 3
Dependent Claim
27 words
