Marine power cables are a type of ship cable, used for power, lighting, and general control purposes in various river and sea vessels as well as offshore oil platforms and other waterborne structures. In the ship's power system, marine power cables play a crucial role, being the lifeblood of the entire vessel. They are responsible for transmitting and distributing electrical power to various electrical equipment on board.

Marine power cables primarily include parameters such as model specifications, number of cores, combustion characteristics, rated voltage, temperature, and nominal cross-sectional area. They comply with standards: IEC60092-350, IEC60092-353, or GB9331-88.
