Abstract:
The invention relates to a grounding conductor and an electrical system comprising such a grounding conductor (100) comprising a plurality of conductive aluminium strands (120) where each such strand is provided with at least one sheath (140) of an electrically conductive polymer material having a volume resistivity (ρ) below 100 Ω⋅cm. Elected for publication.
Abstract:
Herein a self-supporting electric power cable (2) is disclosed. The electric power cable comprises an outer jacket portion (6) and a core portion (8). The core portion (8) comprises at least one insulated conductor (10) and at least one supporting cord (12). The at least one insulated conductor (10) comprises a number of individual wires (14), and the at least one supporting cord (12) comprises synthetic fibres (16). The number of individual wires (14), individually or arranged in bundles (18), are arranged in a first lay direction. The at least one insulated conductor (10) and the at least one supporting cord (12) are arranged in a second lay direction. The at least one supporting cord (12) is arranged as a separate unit in a cross sectional sector of the self-supporting electric power cable (2). Thus flexible and durable power cable for sea use is provided. Also an offshore arrangement is disclosed herein.
