Resin Pot Component for an Inspectable Barrier Cable Gland
A resin pot assembly for use with a barrier cable gland is provided. The resin pot assembly is shaped and dimensioned to locate within an internal cavity of a cooperating barrier cable gland and has a closable end configured to seal onto a cable sheath of a cable in an installed condition. The resin pot assembly has two, coaxial components configured in the installed condition to surround a plurality of individually electrically insulated conductors extending out of the cable sheath. A first hollow component in the form of a clear cylinder provides the closable end of the resin pot assembly and a second hollow component, which is rigid, provides an pen end of the resin pot assembly and is axially spaced apart from the closable end of the resin pot assembly. The resin pot assembly operatively receives a resin mix therein.
Electrical component enclosure with injected seal and method
An enclosure and method for an electrical component having a base portion and a cover portion. The base portion has a first channel which extends about at least a portion of a periphery of the base portion. The cover portion has a second channel which extends about at least a portion of a periphery of the cover portion. The second channel is aligned with the first channel to form a sealant receiving channel. A sealant is provided in the sealant receiving channel. The cover portion has at least one inlet opening configured to receive the sealant as the sealant is injected into the sealant receiving channel. The cover portion has at least one outlet opening configured to allow excess sealant of the sealant to escape from the sealant receiving channel as the sealant is injected into the sealant receiving channel.
JOINT FOR ELECTRICAL CABLES AND METHOD FOR JOINTING
An insulation system for jointing of high voltage conductors has an inner layer made of a crosslinked first polymeric semiconducting material, an intermediate insulating layer made of a thermoplastic polymeric insulating material, and an outer layer made of a second polymeric semiconducting material. The insulation system is adapted for surrounding the electric conductor joint.
Apparatus for dispensing curable material into a cable gland
A dispenser apparatus (10) for dispensing curable liquid material into a space in a cable gland is disclosed. The apparatus comprises a housing (12) for separately storing of components of a curable liquid material and provided with a respective first outlet (14) for each component. A mixing chamber (16) mixes the components to cause curing of the curable liquid material and has an inlet (18) for receiving the components from the first outlets, and a second outlet (20) for the mixed components. A plunger (22) urges the components out of storage chambers of the housing via the first outlets and into the mixing chamber via the inlet. The dispenser apparatus is adapted to be located in a body of a cable gland such that the mixed components are dispensable from, the second outlet into a space defined by the body and a cable extending through the body.
Cable joint assembly
A cable joint assembly and a method for assembling such a cable joint assembly. The cable joint assembly joins at least two cable ends, said cable joint assembly comprising a cable joint defining an interior space into which in use said at least two cable ends extend and are joined and which in use is filled with a liquid, wherein said cable joint assembly further comprises a barrier element that is placeable in said interior space in such a manner, that in use the barrier element extends around the at least two cable ends at least in an area where the at least two cable ends are joined.
Butt closures and bases therefor
A butt closure base includes a base housing defining a plurality of cavities. A first gel is disposed in each of the plurality of cavities. The butt closure base further includes a plurality of wedge assemblies, each of the plurality of wedge assemblies removably insertable into one of the plurality of cavities. Each of the plurality of wedge assemblies includes an outer cover, a second gel, and a main pressure plate in contact with the second gel.
