A termination assembly including an elongate housing having at least one access port and an end adaptor on each opposing end, said end adaptor including a tube adaptor or a moulded cable end adaptor, a terminal block having a plurality of terminals, said terminal block is positionable within the elongate housing, a sealing sleeve for covering the elongate housing, and wherein the termination assembly is fillable with oil and forms part of a sealed electrical cable when connected via the end adaptors to tube containing a wiring loom and/or when connected to a moulded cable.

An assembly can include a barrel housing having an opened end. The barrel housing can also include a barrel port for mounting a first compression fitting. A racetrack tray can be positioned within the barrel housing. The racetrack tray can receive an optical fiber and an electrical cable of a hybrid cable. A cap can be secured to the opened end of the barrel housing. The cap can include a cap port for receiving a second compression fitting. A primary seal can be positioned in a groove on one of the cap or the barrel housing. The primary seal can create a pressure seal between the cap and the barrel housing.

An insulation termination assembly comprises an insulation tube, an annular bottom plate, and a tail assembly. The insulation tube has an inlet end, an outlet end opposite to the inlet end, and an inner space filled with an insulation liquid. The annular bottom plate is mounted at the inlet end of the insulation tube. The tail assembly comprises an insulation connection tube mounted on the annular bottom plate and a shield tail tube connected to the insulation connection tube. A cable joint of a cable is introduced into the inner space of the insulation tube from the inlet end of the insulation tube after passing through the shield tail tube and the insulation connection tube.

The invention is a modular safety device adapted to allow the flow and create a mechanical seal to a series of electric conductors (5) in wellheads, thus, ensuring pressure control and internal hydraulic integrity; it is also a method to repair leaks and/or conductor cables that does not require the use of specialized well maintenance equipment (Work Over). The device and method of the invention uses a sealing case (10) attached to a lower connector (9), joined to a main or intermediating sealing case (8) that seals towards the pipe hanger (3) and attaches to the upper connector (7) that seals towards the upper section of the wellhead (2) and attaches to the protective bushing (26) or the upper sealing case (6) to ensure control of well's pressure during its operation or reparation in case of leaks or failures. This device is useful for pump systems and gas and oil production.

Described herein is 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.

1. A pre-assembled cable assembly for a penetrator body or pothead comprises at least one cable located in a volume of the penetrator body or pothead, the volume around the cable being encapsulated in a low temperature alloy. The cable or cables may include a spliced electrical connection located a volume of the penetrator body or pothead such that the volume around the spliced electrical connection being encapsulated in a low temperature alloy.
