An assembly for use with an oil-filled cable termination includes a cable gland, a cable received in the cable gland, a stress cone received around the cable and spaced apart from the cable gland, and a seal system around the cable between the cable gland and the stress cone. The seal system includes: a first oil seal layer surrounding an upper portion of the cable gland and a portion of the cable between the cable gland and the stress cone, with the first oil seal layer being spaced apart from the stress cone; a second oil seal layer surrounding the first oil seal layer and extending between the cable gland and the stress cone; and a third oil seal layer surrounding the second oil seal layer and extending between the cable gland and the stress cone.

A high-voltage cable sealing end (100) has a primary volume (102) and a secondary volume (104) fluidically connected thereto, which are filled with an insulating fluid. The primary volume (102) and the secondary volume (104) are sealed with respect to the atmosphere surrounding the high-voltage cable sealing end (100). The secondary volume (104) can be disconnected from the primary volume (102) via a separable connection (106) which can be cut off in a fluid-tight manner. A drying agent, which draws moisture out of the insulating fluid, is introduced into the secondary volume (104).
摘要:
A split elastomeric ring for repairing and sealing electrical connection boxes of the type commonly referred to as potheads. The ring has an elastomeric body and a central opening. A slit is provided in the body of the ring so that it may be opened and inserted around the cable at the base of the pothead. A silicone sealant is placed between the ring and the pothead and the ring holds the sealant against the cable and the base of the pothead body.

A device for protecting the end of a high or very high tension electric cable having synthetic insulation from the effects of insulation breakdown, comprises an insulator and a metal enclosure defining a gastight chamber around said end, which chamber contains dielectric gas under pressure and that is separated from ambient air by a rupture disk provided in the metal enclosure. The device further includes a circularly symmetrical collar protecting said insulator and extending inside the chamber around said cable and terminating in a toroidal rim having a convex face directed towards the cable beyond the breakdown zone inside the chamber and at its end distant from the rupture disk. The device is applicable to protecting the end of a very high tension cable.

A branch-off article includes a branch-off member having a body portion and at least two tubes extending from the body portion to an interior region of a splice cavity, with individual break-out members extending through the individual ones of the tubes. End portions of individual ones of the tubes are recovered and sealed to individual ones of the break-out members and the body portion is sealingly secured to a member which surrounds the splice region and the tubes.

Cable plug and method of manufacture in which hardened plugging compound surrounds individually insulated conductors and a radially resilient spring is placed around the compound which holds the spring permanently in a resiliently expanded condition to compress the compound onto the individual insulations of the conductors. In one arrangement a sleeve surrounds and intimately contacts the compound and at least one rib on the inner surface of the sleeve is urged against a complementary groove in the compound by the spring.
