What are the ways to choose marine cables?

Do you know what is marine cable? Marine cable is actually a kind of wire and cable used for power, lighting, control, communication transmission of various ships in the river and sea and offshore or marine buildings, including marine power cables, marine control cables, marine communication cables and so on. So what are the methods in selecting marine cables? The method of selecting marine cable is as follows: 1. According to the use of cable, laying location and working conditions to choose the appropriate cable model. 2. According to the working system of power equipment, power supply type, cable core and load current to choose the appropriate cable cross-section. 3. According to the results of the system short-circuit current calculations, the piece of short-circuit capacity of the cable to meet the requirements. 4. According to the ambient temperature on the cable rated current-carrying capacity to be revised According to the correction coefficient of bundled laying, the rated current-carrying capacity of the cable is corrected, and then, whether the allowable current of the cable is greater than the load current is judged.6. Calibrate the voltage drop of the line, and judge whether the voltage drop of the line is less than the specified value.7. According to the setting value of the protection device, judge whether the cable is coordinated with the protective device; if not, judge whether the appropriate protective device can be changed. Judge whether it is possible to change the suitable protective device or the setting value, otherwise the suitable cable loading surface should be re-selected.
