The selection steps and principles for Marine cables should be based on the cable's application, laying location and working conditions to choose the appropriate cable model. Select the appropriate cable cross-section based on the working system of the electrical equipment, the type of power supply, the cable core, the load current, etc. Based on the calculation results of the system short-circuit current, determine whether the short-circuit capacity of the fragmented cable meets the requirements. Adjust the rated current-carrying capacity of the cable according to the ambient temperature and determine whether the allowable current of the cable is greater than the load current. Based on the bundle correction coefficient, the rated current-carrying capacity of the cable is corrected, and then it is determined that the allowable current of the cable is greater than the load current. Check the voltage drop of the circuit and determine whether it is less than the set value. Determine whether the cable and the protective device are coordinated based on the setting value of the protective device. If there is no coordination, determine whether the appropriate protective device or setting value can be changed; otherwise, a suitable cable carrying surface should be reselected.

The rapid development of China's shipbuilding industry will further drive the market demand for Marine cables. Due to the influence of the working environment on ships, the cables used on ships are mostly halogen-free, low-smoke and salt-alkali resistant special cables. In offshore platform operations, longitudinal water-sealed cables and umbilical cables will be widely applied. Due to the development of the domestic and international shipbuilding industry, the demand for the overall Marine cable industry in our country will also increase significantly. The market demand for wires and cables used in underwater vehicles, torpedoes, underwater decoys and underwater reconnaissance equipment will also increase significantly. In addition, the maintenance of ships and the construction of related facilities such as docks will also provide a large market demand space for other commonly used types of wires and cables.

Marine cables are used for power, lighting and general control in various ships and offshore oil platforms in rivers and oceans. It is used for general control of various ships and offshore oil platforms in rivers and oceans. Signal transmission and control systems used in various communication, electronic computer and information processing equipment. It falls within the category of special wires. Radiation cross-linking technology requires specialized electron irradiation machines. Marine cables, also known as Marine power cables, are wires and cables used for power, lighting and general control in various ships and offshore oil platforms in rivers, seas and oceans. Main uses: It is used for power, lighting and general control of various ships and offshore oil platforms in rivers and oceans. The execution standard for Marine power cables is IEC60092-350, IEC60092-353 or GB9331-88. The main parameters include model specification, core number, combustion characteristics, rated voltage, temperature, nominal cross-sectional area and other main parameters.
