摘要： A skin-effect heating cable (1) comprising an inner conductor arrangement (5), an outer conductor arrangement (3) comprising a material configured to generate heat through hysteresis losses when exposed to an alternating magnetic field, and an inner insulation (7) arranged between the inner conductor arrangement (5) and the outer conductor arrangement (3). The mutual position of the inner conductor arrangement (5) and the outer conductor arrangement (3) is fixed along the axial direction. A pipe assembly with such a cable and a method of heating are also disclosed.

摘要： An offshore high-voltage electric power transmission assembly (1), comprising an AC power supply (101a) at a first location (10) and with P supply phase lines (12a, 12b, 12c), a power-receiver (101b) with P receiving phase lines (16a, 16b, 16c) at a second location (20). A high-voltage offshore cable (3) is arranged between the power supply and the power receiver. The first and/or second location is an offshore location. The cable (3) comprises P x N power cores (11a, 11b, 11c), N and P being 2 or more. N groups of P power cores connect to the respective P supply phase lines and to the respective P receiving phase lines. The power cores are distributed along a core distribution circle (22) in the cross-section of the high-voltage offshore cable. The order of the P power cores (11a, 11b, 11c) within each of the N groups is identical.

摘要： The invention relates to a direct electric heating (DEH) piggyback cable (k3, k4, k5) comprising a power cable (4) to transfer large amounts of electric energy/power, a set of elongate profile elements (2, 3) having apertures, holes or slits for receipt of seawater, said elongate profile elements (2, 3) are laying in a ring around the power cable (4) which are collectively collected into a twisted bundle by means of a laying and closing operation, a protective sheath (1) that encapsulates the power cable (4) and the elongate profile elements (2, 3). At least one of the profile elements (2, 3) and the sheath (1) are made of a semiconducting material in order to drain off to sea capacitive currents arising in the DEH piggyback cable (k3, k4, k5) when the power cable (4) conducts large amounts of electric energy/power.

摘要： The invention relates to a power umbilical (k1, k2, k5, k6, k7, k8) comprising at least one power cable (4) to transfer large amounts of electric energy/power, a set of elongate profile elements, laying at least partly around and between the power cables (4), which are collectively collected into a twisted bundle by means of a laying and closing operation, and a protective sheath (1) encapsulating the at least one power cable (4) and the elongate profile elements (2, 3). The at least one of the elongate profile elements (2, 3), is made of a semiconducting material, said semiconducting material being able to drain off, or dissipate, capacitive currents arising in the power umbilical (k1, k2, k5, k6, k7, k8) when the at least one power cable (4) conducts large amounts of electric energy/power, said elongate profile elements (2, 3) comprising longitudinally channels (9) adapted to communicate with radial extending holes or slits in the profile elements (2, 3) and through the protective sheath (1) such that when the water is filling the channels (9), the holes or slits are transporting the capacitive currents into the surrounding sea water.

摘要： A power distribution system comprising a first transformer (125) at a first location (10) and a second transformer (25) at a second location (20). Two electric end points (P, R), being electric power supplies or consumers, are connected to the first transformer (125) at the first location and two electric end points (Q, S), being electric power supplies or consumers, are connected to the second transformer (25), wherein a cable arrangement (29) comprising a plurality of cable conductors extends between the first and second transformers. The power distribution system is configured to distribute electric power between two electric end points of a respective first pair of end points (P, Q) and a second pair of end points (R, S) at arbitrary direction and simultaneously through the same cable conductors of the cable arrangement (29).
