Abstract

The present invention relates to a method of manufacturing a dynamic power cable (1) comprising the steps of; - providing a cable core (2) comprising; an electrical conductor (3) and an electrically insulating layer (4) arranged radially outside of the electrical conductor (3), - wrapping a metallic sheet (7) radially around the cable core (2), the metallic sheet (7) comprising a copper-nickel alloy, - welding (8) together opposing edges of the metallic sheet (7) to form a continuous water barrier layer (5) around the cable core (2), wherein - the welding (8) is performed by autogenous welding. Furthermore, the invention relates to a dynamic power cable manufactured according to such a method, and the use of autogenous welding to form a water barrier layer (5) in a dynamic power cable (1).
