Abstract
The present disclosure relates to an impact resistant, multipolar power cable (10) comprising, a plurality of cores (1), each core (1) comprising at least one conductive element (3) and an electrical insulating layer (5) in a position radially external to the at least one conductive element (3). The cores (1) are stranded together so as to form an assembled element providing a plurality of interstitial zones (2). An expanded polymeric filler (6) fills the interstitial zones (2) between the plurality of cores (1). An expanded impact resistant layer (7) is in a position radially external to the expanded polymeric filler (6) and comprises a polymer that differs from the expanded polymeric filler (6).
