    Subsea / Underwater / Power / Electrical Cables, Fiber Optic Cables and Hybrid Cables

    Hydro Group design and manufacture subsea underwater electrical cables, fibre optic cables, hybrid cables, tethers and umbilicals for the subsea oil and gas, renewable energy and defence industry. Our focus is on product innovation, design, engineering and manufacturing of harsh environment composite power cables for subsea, underwater, topside and onshore applications. Hydro Group are able to manufacture complete cable harnesses at very short notice and are able to supply short lengths to customers for system trials and system design proofing.


    Our in-house engineering team utilise the latest software to design multi-component cables to meet customer requirements and necessary standards for various subsea applications taking into account the application, location and lifecycle requirements of the cable. Calculations such as voltage drop, current carrying capacity and insulation resistance are analysed to ensure that cables meet the required criteria with further analysis such as fatigue, bending and axial stiffness carried out upon request.


    Cables are manufactured in our state of the art facility in Aberdeen, starting from the bare conductor to extruding the insulation, laying up of components, braiding, armouring, and final extrusion. New manufacturing capabilities now allow the production of cables from only 100 metres to several kilometres in length and diameters from 5mm to 120mm.


    High grade materials are used in manufacture to produce cables with superior abrasion resistance, flexibility and reliability.

    Materials:
    • Polyurethane • EPR • Hytrel • TPR • Megalon • Polyethelene • Cross-linked PE

    The composition of our cables may vary widely:
    Composition:
    • Multi-conductor to give optimum usage for various video and camera type.
    • Twisted screened pairs, triples and quads with foil screening for communication and signal.
    • Insulation compounds suitable for high voltage and various power applications.
    • Sheathing compounds, armouring and braids for various mechanical and environmental requirements.
    • Specialist components such as Fibre Optics, Ethernet and Coaxial.

    The vast majority of our cables are customised to client’s specification, however we keep in stock some of the more popular configurations.
