Applications and types of marine power cables

In recent years, with the vigorous development of global water transportation and marine engineering industries, the demand for marine power cables, as a kind of wire and cable specially used for power, lighting and general control of various ships on rivers and seas and offshore oil platforms and other water buildings, has gradually increased. Compared with land cables, marine cables mostly use armored structure metal wire weaving to enhance their tensile strength, wear resistance and corrosion resistance, ensuring stable and reliable operation in complex water environments.
The main uses of marine cables include: providing power, lighting and general control for various ships on rivers and seas and offshore oil platforms and other water buildings. The implementation standards of marine power cables are IEC60092-350, IEC60092-353 or GB9331-88. The main parameters of marine power cables include model specifications, number of cores, combustion characteristics, rated voltage, temperature, nominal cross-sectional area, etc. According to the purpose, marine cables can be divided into the following categories
1. Cables for lighting and power circuits: This type of cable is mainly used for the lighting system and power system of ships to ensure the normal operation of ships under various navigation conditions.
2. Cables for control and communication loops: These cables are used in the ship's control system, communication system and data transmission system to achieve ship automation control and information transmission.
3. Cables for telephone loops: These cables are used in the ship's telephone communication system to achieve real-time communication between the ship and the outside world
4. Cables for distribution boards: These cables are used in the ship's distribution board system to provide stable power for various devices
5. Cables for movable devices: These cables are used to connect movable devices, such as lifeboats, submersibles, etc., to ensure that the equipment can be quickly separated from the ship when an accident occurs on the ship.
6. Cables for internal wiring of control equipment: These cables are used for wiring inside the control equipment to achieve signal transmission and control functions between devices.
7. Cables for other special devices: These cables are used for special devices on ships, such as underwater detection equipment, radar equipment, etc. to meet power requirements in special scenarios.
