Technical Specifications Feeder Cable
At the onset of the project, the following goals were laid down for the design of the new feeder cable:
- Watertightness: Less chance of water intrusion and improved longitudinal watertightness, so no water transport in longitudinal direction.
- Robust: Better suited against damage during usage, stronger cover. Additionally, higher breaking strength.
- Resistance in the water: Reducing resistance in the water, reducing diameter.
- Visibility: Brightly coloured outside cover.
- Repair possibilities: Cable should be easy to repair.
- Termination: Reducing chances of leakage at transition from cable to beam, improvement of tensile release. It should be possible to realise termination easily and fast.
- Improvement of cable guiding: Improvement of cable guiding so that the life expectancy of the cable is increased. Adjust cable guiding and cable design to each other.
Preconditions:
- Weight: Equal or lower per running meter so that the set-up of the winch will not cause stability issues in smaller ships.
- Radius: The bending radius of the cable should enable the use of a compact winch because the cable will be used on smaller ships.
In cooperation with De Regt Marine Cables a cable with the following specifications was chosen. This cable was brought into use by various fishermen and tested for over a year:
- Copper conductors 4 x Ø 5.1 mm (feed);
- 1 x twister quad Ø 2.4 mm (communication);
- 2-layered reinforcement from non-extensible synthetic fibre, torque balanced;
- Reinforced 1.5 mm thick PUR cover.
The 2-layered reinforcement is twined in such a way that the cable does not turn (does not wrench) under tensile strain. The total diameter of the cable is Ø 20 mm.
Option: fairing: dyneema hairy fairing. Fairing increases the cable diameter to Ø 22.8 mm.
