ABSTRACT:
A reinforced cable having hauling, electrical and hydraulic lines. The cable has a substantially rectangular cross section and includes at least one internal support to protect these lines by resisting external compressive forces, and yet is bendable about one of its transverse axes for easy storage on and deployment from a drum. The internal support also protects the hauling lines from compressive forces applied longitudinally thereof by resisting radial displacement of the hauling lines. In one embodiment, the cable comprises an armor layer, a pair of engaged channels inside the armor layer, and a pair of corrugated supports inside the channels and fixedly spaced apart. The hauling lines, in the form of wire ropes, are located inside the corrugated supports, while the electrical lines are located inside the channels between the corrugated supports. The hydraulic lines can alternatively be located inside the channels between the corrugated supports, or inside the wire ropes. Any spaces inside the channels are filled by elastomeric material. In another embodiment, the cable comprises a rigid tubular support located between and engaging the wire ropes, and an armor layer engaging and enclosing the tubular support and the wire ropes. In this embodiment, the electrical conductor is located inside the tubular support.
