Marine power cables are cables specially used in ship power systems, mainly used for power transmission of various ships in rivers and seas and water buildings such as offshore oil platforms. Marine power cables play a vital role in ship power systems. They are the lifeblood of the entire ship and are responsible for transmitting and distributing electrical energy for various electrical equipment on board.

Standards and certification of marine power cables
Power transmission: Provide power for various electrical equipment on board, including lighting, control host, etc.
Safety assurance: Ensure the stable operation of the ship power system and ensure the safety and normal operation of the ship.
Marine power cables are different from ordinary cables. Due to their special working environment, they have higher technical and material requirements. Marine cables usually need to meet the following performance requirements:
Electrical performance: Good conductivity and insulation performance.
Mechanical properties: High tensile strength and wear resistance.
Aging resistance: Can be used for a long time in harsh environments without aging.
Moisture-resistant, oil-resistant and cold-resistant performance: Adapt to the use requirements of ships in different environments3.
Marine power cables can be divided into the following categories according to their uses:
Rated voltage 0.6/1KV cross-linked polyethylene insulated low-voltage halogen-free flame-retardant (or fire-resistant) marine power cable: Suitable for low-voltage power systems.
Rated voltage 150/250V cross-linked polyethylene insulated low-voltage halogen-free flame-retardant (or fire-resistant) marine communication cable: Suitable for communication systems.
The standards for marine cables include: IEC60092-350, IEC60092-353, IEC60092-351, IEC60092-359, IEC60228, IEC60332-3-22, IEC60331-21, IEC60754-1, IEC60754-2, IEC61034-2, etc. These standards ensure the safety and reliability of marine cables in various environments.
