The present invention relates to the technical field of subsea power cables. More specifically, the invention relates to a subsea power cable comprising at least one cable core, the cable core comprising a metal conductor, the metal conductor comprising at least one metal wire, wherein a section of the at least one metal wire along the longitudinal direction is surrounded with a material of low electrical conductivity.

A structure fabricated of a zeolite-based paste with an intra-layer continuous wire embedded is disclosed. Vitally, the continuous wire is extended past the bounds of the structure's walls, creating bare wire leads that allow for connection to a power source for electrification. The structure is made of multiple layers stacked together, typically in an additive manufacturing (3D printing) process. Within this structure, at least one layer has an embedded wire running through at least some portion of it, and is equipped with two bare wire leads protruding from the structure. This wire is designed to act as a heating element for uniform Joule heating of the zeolite structure for reduced power consumption and temperature ramp-up time during a desorption process, as well as reduced system footprint and enhanced mechanical properties. The frequency of wire embedment (a wire embedded in every n.sup.th layer), the percentage of the embedded layer that contains the wire, and the wire gauge and material/composition can be modified for the desired application.

An electrical feedthrough includes a base body with a sealing region, at least one opening and an electrical conductor fed through the opening, wherein the conductor is held in the opening by a fixing material and the fixing material seals the opening. The edges which surround the opening are designed to be sharp and all edges of an outer contour of the base body are provided with a chamfer or a rounding, which has a size or a radius r in the range of 0.3 mm to 2 mm.

An insulator that supports a line from a pin includes a core that defines an opening configured to receive the pin, and includes a shell formed from a polymer disposed over an outer surface of the core. The insulator also includes a head formed from the core or the shell, and configured to support the line spaced from the pin.

An electrical feedthrough includes: a main body having a through-opening running through the main body and comprising titanium or titanium alloy; an insulation material accommodated in the through-opening, the insulation material comprising a glass; and an electrical conductor that extends through the insulation material accommodated in the through-opening. The glass is a lanthanum borate glass comprising the following components (in mol % based on oxide): 22.0-37.0 B.sub.2O.sub.3; 1.0-12.0 La.sub.2O.sub.3; 10.5-23.0 SiO.sub.2; 29.0-45.0 RO (MgO+CaO+SrO); 0.1-6.0 Nb.sub.2O.sub.5+ZrO.sub.2+TiO.sub.2+Ta.sub.2O.sub.5; and greater than 3.00 SiO.sub.2/(Nb.sub.2O.sub.5+ZrO.sub.2+TiO.sub.2+Ta.sub.2O.sub.5). The glass, on determination of hydrolytic stability in accordance with DIN ISO 720:2021-12, has an Na.sub.2O equivalence value of <1250 g/g. The feedthrough has long-term autoclaving stability and an insulation resistance of the feedthrough after 300 autoclaving operations is at least 1*10.sup.9 ohms.
