摘要： 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.

摘要： A self-supporting cable including an outer portion and an inner portion is provided, as well as a combination of a self-supporting cable and a suspension arrangement. The inner portion includes at least one insulated conductor and the outer portion includes a first inner surface and an external surface. The external surface is arranged to engage with a suspension arrangement. The inner portion includes a first outer surface, the first outer surface abutting against the first inner surface. The outer portion includes an outer layer and a metal tape adhered to the outer layer. The outer layer includes the external surface, and the metal tape includes the first inner surface. The first inner surface being of metal and adapted for, during local load, frictional engagement with the material of the first outer surface increases the effectiveness of a functional grip between first outer surface and first inner surface.
