Abstract
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.
Claims27
A device for electric connection to an energy supply conductor for intermediate and high voltage, comprising:
- an insulation part;
- and
- a voltage-carrying part adapted to be connected to an intermediate or high-voltage source, wherein the voltage-carrying part is surrounded by an outer shell formed by said insulation part and wherein the insulation part comprises a thermoplastic polymer, wherein at least along a part of a length of the voltage-carrying part, the outer shell extends with a spacing between an inner periphery of the outer shell and an outer periphery of the voltage-carrying part.
A method of producing a device for electric connection to an energy supply conductor for intermediate and high voltage, the method comprising:
- forming an outer shell by molding a thermoplastic resin around a voltage-carrying part adapted to be connected to an intermediate or high voltage source, wherein at least along a part of the length of the voltage-carrying part, the outer shell is molded with a spacing between an inner periphery and an outer periphery of the voltage-carrying part.
The method according to clam 22, wherein the outer shell and the barrier element are interconnected by being moulded together into one single piece.
An electric station comprising a grounded wall element, comprising:
- a device passing through said wall element, the device comprising an insulation part;
- and a voltage-carrying part adapted to be connected to an intermediate or high-voltage source, wherein the voltage-carrying part is surrounded by an outer shell formed by said insulation part and wherein the insulation part comprises a thermoplastic polymer, wherein at least along a part of a length of the voltage-carrying part, the outer shell extends with a spacing between an inner periphery of the outer shell and an outer periphery of the voltage-carrying part.
