Abstract
Abstract An electrical penetration assembly for passing electrical conductors through the wall of a pressure containment vessel. The electrical penetration assembly is comprised of at least two header members having passages through which the electrical conductors pass and are sealed. Preformed electrical insulator support members having openings for conductors are provided within the passages provided in the header members and silicone elastomer potting sealant compound is introduced into the passages to seal the conductors within the openings in said support members and within the passages in said headers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
204 words
An electrical penetration assembly for a containment vessel and for insertion into a penetration nozzle sealed in the wall of said vessel, said electrical penetration assembly comprising a pair of spaced header members, an envelope portion between said headers defining a vapor and pressure sealed monitoring region between said headers, each of said header members having at least one passageway therethrough, an insulating spacer member fitted within a portion of each passageway of each header member, with at least one aperture through said insulating spacer member, an electrical conductor passing through said aperture in said insulating spacer member and extending through said passageway of each header member, with a silicone elastomeric potting material filling the remainder oF each passageway and extending beyond each of the passageways as a wafer across the back surface of each header member, a tubular shroud member sealingly secured to and extending from the back surface of each header member, said shroud member encompassing said wafer of silicone elastomeric potting material, and a second less resilient potting material substantially filling the remainder of each said shroud member sealing each shroud member, with said electrical conductor sealingly passing through said silicone elastomeric potting material and said second less resilient potting material.
Claim 2
Dependent Claim
204 words
An electrical penetration assembly for a containment vessel and for insertion into a penetration nozzle sealed in the wall of said vessel, said electrical penetration assembly comprising a pair of spaced header members, an envelope portion between said headers defining a vapor and pressure sealed monitoring region between said headers, each of said header members having at least one passageway therethrough, an insulating spacer member fitted within a portion of each passageway of each header member, with at least one aperture through said insulating spacer member, an electrical conductor passing through said aperture in said insulating spacer member and extending through said passageway of each header member, with a silicone elastomeric potting material filling the remainder oF each passageway and extending beyond each of the passageways as a wafer across the back surface of each header member, a tubular shroud member sealingly secured to and extending from the back surface of each header member, said shroud member encompassing said wafer of silicone elastomeric potting material, and a second less resilient potting material substantially filling the remainder of each said shroud member sealing each shroud member, with said electrical conductor sealingly passing through said silicone elastomeric potting material and said second less resilient potting material.
Claim 3
Dependent Claim
18 words
The assembly set forth in claim 1 in which the less resilient potting material is an epoxy resin.
Claim 4
Dependent Claim
21 words
The assembly specified in claim 1, wherein said insulating spacer member extends through the monitoring region between each of said headers.
Claim 5
Dependent Claim
70 words
The assembly set forth in claim 1, wherein one of said header members is the inner header, with the passageway through the inner header having an inwardly extending shoulder portion, and said insulating spacer member has an outwardly extending shoulder portion which fits the inner header shoulder portion to lock said insulating spacer member within said inner header passageway with respect to any forces directed outwardly from said containment vessel.
Claim 6
Dependent Claim
58 words
The assembly specified in claim 1, wherein a plurality of passageways are provided through said headers, with an apertured insulating spacer member within a portion of each said passageway, with electrical conductors passing through each apertured insulating spacer member, and also sealingly passing through each said passageway, said silicone elastomeric potting material, and said less resilient potting material.
