A power umbilical for transfer of large amounts of electric power, fluids and electric current/signals from the sea surface to equipment deployed on the sea bed, in particular in deep waters includes a number of electric power conducting cables, pipes and electric conductors/wires collected in a bundle, a filler material lying at least partly around and between the pipes, cables and the conductors/wires, and a protective sheath enclosing the pipes, cables conductors/wires and filler material. The load carrying elements of the power umbilical are light weighted rods of composite material that can either be collected in bundles or appear individually or in a combination thereof.
