A low voltage electric power cable includes at least two insulated conductors arranged together in a bundle, at least one foil extending around the bundle, and an outer sheath extending around the at least one foil. A recess is formed between two insulated conductors. The low voltage electric power cable includes an elongated member, the elongated member being arranged between the at least one foil and the outer sheath, and extending adjacent to the at least one foil along the recess. The elongated member is arranged with a clearance fit underneath the outer sheath.

Low voltage electric power cable

A self-supporting electric power cable is disclosed. The electric power cable includes an outer jacket portion and a core portion. The core portion includes at least one insulated conductor and at least one supporting cord. The at least one insulated conductor includes a number of individual wires, and the at least one supporting cord includes synthetic fibers. The number of individual wires, individually or arranged in bundles, are arranged in a first lay direction. The at least one insulated conductor and the at least one supporting cord are arranged in a second lay direction. The at least one supporting cord is arranged as a separate unit in a cross sectional sector of the self-supporting electric power cable. Thus flexible and durable power cable for sea use is provided. Also an offshore arrangement is disclosed herein.

The application relates to a grounding conductor and an electrical system including such a grounding conductor including a plurality of conductive aluminum strands where each such strand is provided with at least one sheath of an electrically conductive polymer material having a volume resistivity (&#x3c1;) below 100 &#x3a9;&#xb7;cm.

Grounding conductor, electrical power system and use of grounding conductor

The figure shows an electrical cable with conductors () of metal, surrounded by each of an inner conducting layer (), insulation () and an outer conducting layer (). A moisture barrier () with an electrically conducting layer surrounds the conductors. Shield strips () of at least partially conducting material are located in the regions between the outer conducting layer () and the moisture barrier (). Electrically conducting shield wires () run along the shield strips and are placed through these into electrical contact with the electrically conducting layer of the moisture barrier (). The shield strips support the moisture barrier from the inside, such that the moisture barrier can in a simple manner be made watertight when it is applied. The shield strips (), the moisture barrier () and the shield wires () together constitute an efficient electrical shield for the cable. Penetration of an electrically conducting object into the cable results in a fault current that can be easily indicated, such that an applied cable voltage can be removed.
