Abstract: Umbilical device, where the device has a longitudinal axis (x), and includes at least one elongated electrical cable or tube element; and an elongated load bearing component along the longitudinal axis (x) and having an external surface including at least one groove disposed along the longitudinal axis (x) and parallel thereof. The component includes a central core encompassed by a plastic or elastic layer, which is provided with the at least one groove, where the groove is designed for holding the cable or tube element within it, while allowing the cable or tube element to move substantially radially in the groove when the umbilical is bent and that the layer is made from several plastic or elastic elements.

Abstract: The invention relates to a flexible electrical elongated device, suitable for service in a high mechanical load environment, wherein said device has a longitudinal axis, and comprises: at least one elongated electrical conductor element, an elongated load bearing component along said longitudinal axis and having an external surface including at least one groove disposed along said longitudinal axis, said groove being designed for holding said conductor element within it while allowing said conductor element to move substantially radially when said device is bent.
