A pressurisation and heating device for restoring an insulation system of a power cable, the pressurisation and heating device including: a first part including a first channel configured to receive a portion of the power cable, a second part including a second channel configured to receive a portion of the power cable, wherein the pressurisation and heating device is configured to be set in a closed state in which the first channel faces the second channel thereby forming a heating chamber extending from a first end to a second end, opposite the first end, of the pressurisation and heating device, wherein the pressurisation and heating device is configured to be pressurised to obtain a pressure higher than atmospheric pressure inside the heating chamber when the power cable is arranged sealed in the heating chamber, wherein the pressurisation and heating device has an at least 20 cm long axially extending section which is primarily made of material at most having a conductivity of the order of moo S/m at 20° C.

A cable joint includes a cable joint body, a conductive connector disposed within the cable joint body and electrically connecting a first cable to a second cable, and a first conductive element electrically connecting a first shielding layer of the first cable to a second shielding layer of the second cable. The cable joint body includes a first insulating sleeve and a re-jacketing sleeve at least partly encompassing the first insulating sleeve. The re-jacketing sleeve forms a channel along a longitudinal axis of the first insulating sleeve. The first conductive element is disposed within the channel. The channel is collapsed after heat shrinking the first insulating sleeve and the re-jacketing sleeve.

A high voltage connection between a first line of a traveling wave tube and a second line of a voltage supply unit for the traveling wave tube includes a plug which is connected to an end section of the first line or of the second line by a crimp connection, and a socket which is connected to an end section of the other line by a crimp connection. Furthermore, a method for manufacturing a high voltage connection is also described.

A technique facilitates formation of secure connections for use in downhole environments. According to an embodiment, a connector may be constructed as a dry mate connector which provides both a sealed connection and a connection able to withstand a predetermined tensile loading. The connector comprises connector ends combined with an outer connector housing. Additionally, the connector comprises a shape memory alloy sealing system which may be activated to form a secure seal with a corresponding cable or other component feature. The connector also comprises a shape memory alloy retainer system which may be activated to securely grip the corresponding cable or other component feature so as to withstand substantial tensile loading acting on the corresponding cable or other component feature.

Disclosed are various embodiments of LED lamps that are both watertight and waterproof for use in outdoor venues. The LED lamps can easily be assembled using automated or manual techniques and provide a reliable source of outdoor lighting for many years. Simple and inexpensive techniques are used to assemble the LED lamps that allow the lamps to be produced at a reasonable price.
