Marine Cable
Jul 10, 2018

Marine cables are used to connect various electrical equipment in the ship grid to transmit electrical or electrical signals. As the degree of electrification and automation of ships continues to increase, the variety and usage of marine cables continues to increase.


Marine cables are basically divided into three categories: power cables, communication cables and special high-frequency cables. Power cables are used in power, lighting and other systems, and are the most used cables on board.


For power cables, the current carrying capacity is an important technical indicator. The magnitude of the current carrying capacity generally depends on the temperature rating of the cable insulation. Under the same laying conditions, the higher the temperature resistance level, the larger the current carrying capacity. 


If the ambient temperature is high and the selected cable insulation temperature resistance level is low, the allowable temperature rise caused by the current heating is low, which is uneconomical.


The sheath of the marine cable shall have the properties of moisture resistance, oil resistance, combustion resistance and heat aging resistance. Commonly used sheathing materials are neoprene, chlorosulfonated polyethylene and polyvinyl chloride, in addition to lead sheathing.
