Cable carriers

Quelle: Igus | Inka Krischke,

Use on deep drilling rigs

Deep drilling rigs with top drive systems are used to extract oil from the earth. Until now, manufacturers and operators have relied on so-called 'service loops' for the cable feed of the systems. Now there is a new solution from Igus.

With 'service loops', the cables have no guidance, they do not have a defined bending radius and, in the worst case, they can break when moving. Igus has developed the e-loop energy chain so that cables with large cross-sections and high weights can be safely guided in suspended applications: This is a round, three-dimensional modular system that can move cables with a defined bending radius in a strain-relieved manner. The modular energy chain can be opened from the outside and continuously filled. The links can be replaced at any time. Multiple secured screw connections are used between the elements of the cable carrier to prevent components from falling down. As deep drilling rigs have to change their location regularly, the chain has bolted connection elements that enable quick disassembly. In addition to use on deep drilling rigs, the saltwater-resistant 'e-loop' is suitable for suspended applications in the offshore industry, for construction machinery, shore power or wind turbines. High vibrations, lateral impacts and shocks cannot harm the system. The cable carrier is built around a high-tensile plastic cable that absorbs the tensile forces of the cables. The cable is made of a synthetic plastic fiber and is therefore unbreakable, weather-resistant, flexible and corrosion-free. The cable carrier can bear weights of up to 220 kN with the cable.
