摘要：
A power cable (C1), or power umbilical, comprising a number of electric high power cables (10) for transfer of large amounts of electric power/energy; filler material (2, 3, 4, 5, 6) in the form of stiff elongate plastic elements; the number of electric high power cables (10) and stiff elongate plastic elements (2, 3, 4, 5, 6) being gathered in a twisted bundle by means of a laying operation; a protective sheath (1) that encompasses the electric cables and the filler material; and at least one longitudinally extending channel (6) is provided for forced flow transportation of a cooling agent through said power cable/umbilical in order to cool down the electric high power cables (10) and their insulation material from a critical temperature value of about 90° C.
