A connection assembly connects at least two subsea cables to a dual output subsea sensor. An embodiment includes an adapter piece mounted to a rear part of the subsea sensor; a sensor port in the adapter piece, through which at least a first sensor connection and a second sensor connection are led to the subsea sensor; a first and second port for respectively providing a connection to a first and second subsea cable; a first penetrator providing a liquid tight seal between an interior space of the adapter piece and a duct connected to the first port; and a second penetrator providing a liquid tight seal between the interior space of the adapter piece and a duct connected to the second port. The sealing provided by the first and second penetrator preventing fluid communication between the respective duct connected to the first and second port, through the adapter piece.

A connection assembly includes an adapter to be mounted to a rear part of a subsea sensor, a sensor port being located in the adapter, through which at least a first and a second sensor connection are led to the subsea sensor; a first port for providing a connection to a first of the subsea cables; and a second port for providing a connection to a second of the subsea cables. A first penetrator is arranged in the first port to provide a liquid tight seal between an interior space of the adapter and a duct connected to the first port leading the first sensor connection through the first port, and a second penetrator is arranged in the second port providing a liquid tight seal between the interior space of the adapter and a duct connected to the second port and leading the second sensor connection through the second port.

A cable water stop structure for a cable that includes plural insulated wires and a sheath covering the plural insulated wires includes a heat shrinkable tube that is shrunk to wrap around an end of the sheath and the plurality of insulated wires extending from the end, and a cover that is attached to sandwich the end of the sheath, the plurality of insulated wires extending from the end and the heat shrinkable tube. The cover includes a gripping portion gripping the heat shrinkable tube to restrict the heat shrinkable tube from moving along a cable longitudinal direction.

A process for producing a flexible vulcanized joint between two electric power cables includes the steps of: producing an exposed conductor joint between each end of the two cable ends to be joined; producing an inner semi-conducting layer thereby radially surrounding and covering the exposed conductor joint; winding an insulation tape including an organic peroxide around the inner semi-conducting layer thereby radially surrounding and covering the inner semi-conducting layer; curing the insulation tape to produce an insulation layer; and producing an outer semi-conducting layer thereby radially surrounding and covering the insulation layer. The step of winding the insulation tape around the inner semi-conductor layer is performed under an oxygen-free atmosphere. The present invention also provides a flexible vulcanized joint produced by this process, and an electric power cable including such a joint.

A telecommunications enclosure is provided with reliable sealing around cables entering therein. The enclosure includes one or more cable ports with cable seals made from a material that includes an oil-bleed silicone rubber. The cable ports may also have a convoluted or serrated inner surface configured to engage and support the cable seals.

The arrangement includes a fire-resistant cable connection, a cable connection method using such a fire-resistant connection, and a line of fire-resistant cables comprising such a fire-resistant connection.

A high pressure cable reinforcement sleeve comprising two or more bracket elements that are capable of forming a sleeve for surrounding a cable joint, where each bracket element comprises an outer wall, where each bracket element further comprises at least one inner protruding wall element.

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.

A curing material, having a solubility parameter of 9.4 or more, contains at least a chain transfer agent that contains a compound containing a polyether structure and two or more urethane bonds or two or more urea bonds in a molecule, and a metal-containing compound. A wire harness is manufactured by supplying the curing material to a conductor exposed portion of a wire bundle including a plurality of bundled insulated wires each having a conductor covered with a covering material made of an insulating body, the conductor exposed portion being formed by removing a part of the covering material of the wire bundle to expose the conductor inside; and curing the curing material by irradiating light in a state in which a surface of the curing material is covered with a protective member formed from a resin containing a plasticizer and having light transmissivity, thereby forming a waterproof portion.

The present invention relates to an accessory for high-voltage direct-current (HVDC) energy cables comprising: at least one element made from a crosslinked elastomeric polymer material, and at least one scavenging layer comprising zeolite particles. The zeolite particles are able to scavenge, very efficiently and irreversibly, the by-products deriving from the cross-linking reaction, so as to avoid space charge accumulation in the element during the accessory lifespan. Moreover, the zeolite particles can prevent the crosslinking by-products present in the element of a non-degassed accessory from migrating towards the insulating layer of the energy cable on which the accessory is mounted.
