Abstract: A DC cable for high voltages has at least an inner conductor (8) surrounded by an insulating layer (10) configured to take the voltage to be taken between the conductor and the surroundings of the cable. The insulating layer is formed by a plurality of superimposed film-like layers (12) of insulating material each having isolated areas of metal (13) on top thereof. The metal areas of consecutive such film-like layers are at least partially overlapping each other as seen in the radial direction of the cable so as to create a large number of small capacitors in said insulating layer of the cable.

Abstract: A device (13) to break an electrical current flowing through a power transmission or distribution line (14) comprises a parallel connection of a main breaker (8) and a non-linear resistor (11), where the main breaker (8) comprises at least one power semiconductor switch of a first current direction. The device (13) further comprises a series connection of a high speed switch (10) comprising at least one mechanical switch and of an auxiliary breaker (9), the auxiliary breaker having a smaller on-resistance than the main breaker (8) and comprising at least one power semiconductor switch of the first current direction. The series connection is connected in parallel to the parallel connection. In a method to use the device (13) first the auxiliary breaker (9) is opened, thereby commutating the current to the main breaker (8), afterwards the high speed switch (10) is opened and afterwards the main breaker (8) is opened thereby commutating the current to the non-linear resistor (11). The device (13) can further be used in a current limiting arrangement.
