ABSTRACT:
The present invention relates to an arrangement in a cable, especially a hydro electric control cable, which has a plurality of hydraulic tubes and electrical cables. In order to arrive at such an arrangement which allows for a required volume of service fluid while retaining an optimum minimum bending radius, the present invention suggests that the cable is designed as an umbilical (1, 101) with three centrally arranged tubes (2) in helical configuration which are surrounded by a ring of electrical cables and hydraulic tubes to allow for lower minimum bend radius (MBR).
