The

requirements for marine cables

The requirements

for marine cables properties in shipbuilding are growing due to the increasing demand

for low weight and high efficiency. Ship cables have to be installed in narrow spaces

demanding highest cable flexibility. Furthermore, marine cables often have to be

halogen free, flame retardant and self-extinguishing.

Ship cables are not

allowed to enhance flame propagation. Additionally maritime wires should have a

low own weight and besides correspond to different international approvals.

Cables, equipment,

protective devices etc. shall be clearly marked as far as is necessary in addition

to the manufacturer’s markings so that they can be identified. Marking shall also

be used to the extent necessary to prevent danger.

Flexible cables with

an earth conductor are required to have an earthing plug. Flexible cables without

an earth conductor are required to have a plug without an earthing contact. Flexible

cables for Class II equipment (double-insulated) are not required to have an earth

conductor, but may have an earthing plug. Flexible cables are required to be connected

in the room where the relevant equipment is used. This does not apply to equipment

designed to be moved during use or for temporary use.

When cables are laid

behind panels or deck-platings, these are to be easily removable. The cables are

to be directly available when the panel or deck-plating is removed. However, single

cables for lamps, socket-outlets and switches in dry areas may be installed behind

wall panels, which are not easy to remove. The requirements that panels or deck

platings, are to be “easily removable” means that the panels or deck platings have

to be hinged or fixed by screws in such a way that they can be dismantled without

difficulty. Such panels or deck-platings should be able to be dismantled without

damaging the interior.
