This invention is a device for connecting an end of a HV cable to an HV installation, comprising a pre-fabricated pipe-like unit (2) and the method for installing this device. The pipe-like unit comprises a connection piece (6, 6b) made out of an electrically conducting material and an insulator tube (5, 5r) which is connected to the connection piece (6, 6b) in a fluid-tight way. The insulator tube (5, 5r) is made out of an insulating material. The HV installation is typically a HV joint or a termination.

An enhanced breakdown strength dielectric material comprises a base dielectric layer having first and second opposing major surfaces. A first stress mitigating layer is disposed on the first major surface of the base dielectric layer. A second stress mitigating layer disposed on the second major surface of the base dielectric layer. A volume conductivity of at least one of the first and second stress mitigating layers is at least 2 times a volume conductivity of the base dielectric layer.

A cable (100) includes a power wire (1), a ground wire (3), data transmission wires (2) between the power wire and the ground wire, and an insulating outer layer (4) enclosing the outer side of the power wire, the ground wire, and the data transmission wires. The power wire includes a conductor (11), an insulating layer (12) outside the conductor, and a metal shielding layer (13) outside the insulating layer. The power wire and the data transmission wires are spaced from each other by plastic materials.

The present invention relates to a crosslinked polymer composition comprising a crosslinked polyolefin, wherein the polymer composition comprises, prior to crosslinking, a polyolefin and peroxide which is in an amount of less than 35 mmol —O—O-/kg polymer composition, characterized in that the crosslinked polymer composition has been in a direct contact with a semiconductive composition for 24 h at 70° C., and that the crosslinked polymer composition thereafter has an electrical DC-conductivity of 150 fS/m or less, wherein the electrical DC-conductivity is measured in accordance with “DC conductivity method”, as described under “Determination methods”, on a plaque of the crosslinked polymer composition at 70° C. and 30 kV/mm mean electric field from a non-degassed and 1 mm thick plaque sample of the crosslinked polymer composition; a layered structure, cable, e.g. a power cable, use of the crosslinked polymer composition and the structured layer, both, for producing a crosslinked power cable, e.g., a cross linked direct current (DC) power cable; and a process for producing a cable.

A single line (6) for a charging cable comprises an open support structure (011, 012) with a longitudinal extent, a conductor braid (2) composed of conductors and an insulating element (3). The conductor braid (2) directly covers the open support structure (011, 012) along its longitudinal extent. The insulation element (3) covers the open support structure (011, 012) and the conductor braid (2). There is at least one duct (4) for a cooling fluid (5) in the single line (6). This duct (4) is formed by the support structure (011, 012) and the conductor braid (2). The insulation element (3) cannot be penetrated by the cooling fluid (5) and is electrically insulating.

A cable is provided for suspending a down hole pump that has a core with at least one tube for the transport of fluid and at least one conductor covered with an insulation layer made of a high temperature resistant insulating material. The core is covered by a steel tape and a first layer of steel wires are positioned radially outside the steel tape in contact with the steel tape. The wires of the first layer of steel wires are positioned side by side around the core with no filler in between the steel wires and an outer layer made of heat resistant polymer covers the steel wires.
