The present invention relates to an insulated pipe comprising one or more inner pipes comprising a plastic, a flexible vacuum insulation panel surrounding the one or more inner pipes, and an outer jacket.

Insulated pipe

This invention relates to a polymeric pipe, and more particularly a polymeric pipe where the pipe comprises a cross-linked polyolefin formed from extruded polyolefin comprising a bismaleimido crosslinker. This invention relates to the manufacturing of plastic pipes and tubing of polyolefinic polymers such as polyethylene, with crosslinking by a bismaleimido crosslinker, to produce crosslinked polyethylene (PEX) pipes and tubing.

Polyolefin pipe

A device for electric connection to an energy supply conductor for intermediate and high voltage. The device includes an insulation part and an electrically conducting voltage-carrying part. The voltage-carrying part is surrounded by an outer shell formed by the insulation part. The insulation part is formed by a thermoplastic polymer. At least along a part of the length of the voltage-carrying part, the outer shell extends with a spacing between its inner periphery and the outer periphery of the voltage-carrying part.

Electric connection device and a method of producing such a device

A device for electric connection to an energy supply conductor for medium and/or high voltage having a voltage-carrying element with an outer periphery, and a tubular outer shell with an inner periphery, the outer shell being formed by a polymer, and along at least a part of the axial extension of the element the outer shell extends axially with a space between its inner periphery and the outer periphery of the element, at least along a section of said part of the axial extension of the element the space is filled with a filler of an electrically insulating material other than that of the outer shell. An electric installation including the device, and a method for producing the device.

Device for electric connection, a method for producing such a device, and an electric installation

A device for electric connection to an energy supply conductor for medium and high voltage, including: a voltage-carrying element; a tubular outer shell formed by a thermoplastic polymer and connected to the voltage carrying element; wherein the voltage-carrying element extends in a longitudinal direction of the tubular shell, and wherein, at least along a part of the length of the voltage-carrying element, the outer shell extends in a longitudinal direction with a space between its inner periphery and an outer periphery of the voltage-carrying element; the outer shell being provided with an outer contact surface to be connected to a wall of a gas-tight container somewhere along the part of the length of the voltage-carrying element; wherein the outer shell is arranged so as to separate said space from an atmosphere outside a container to which the device may be connected. At least along a section of the part of the length of the voltage-carrying element the space is filled with a filler of an electrically insulating material other than that of the outer shell, the filler completely filling the space along the section.
