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).

Provided is an interface for connecting a cable arranged in a shell to a receiving structure, the interface including: a connector including a connection area for fixing the connector to a cable support of the receiving structure and a transmission area for receiving the cable and the shell, a lower seal, an upper seal, a chamber element configured to coat the cable between the lower seal and the upper seal. Also provided is a hang-off system and a method for connecting a cable arranged in a shell to a receiving structure.

A modular safety apparatus adapted to allow the flow and create a mechanical seal for a series of electric conductors in wellheads, thus, ensuring pressure control and internal hydraulic integrity and allowing for a method to repair leaks and/or conductor cables that does not require the use of specialized well maintenance equipment, comprising a sealing case attached to a lower connector, joined to another main or intermediating sealing case. The case seals towards the pipe hanger and attaches to the upper connector that seals towards the upper section of the wellhead and attaches to the protective bushing or the upper sealing case to ensure control of well's pressure during its operation or reparation in case of leaks or failures.

A seal system for an oil-filled cable termination including a cable extending through each of a cable gland and a stress cone that is spaced apart from the cable gland. The seal system includes: a first oil seal layer surrounding the cable between the cable gland and the stress cone; a second oil seal layer overlapping and contacting the first oil seal layer; a first oil barrier layer overlapping and contacting an upper portion of the second oil seal layer; a second oil barrier layer overlapping and contacting a lower portion of the second oil seal layer, the second oil barrier layer spaced apart from the first oil barrier layer; and a heat shrinkable tube secured around the first and second oil barrier layers.
