about marine cable

Marine cable--specialty cable

Marine cable is a cable product designed for ships and ocean engineering, which is a special cable. Its product models are diverse, such as IEC60092-353, IEC60092-353, IEC60092-376. technical specifications, with high resistance to pressure, abrasion, corrosion and other characteristics. They are usually applied to power, lighting, communication and control systems in ships. In terms of usage scenarios, it can be widely used in all kinds of ships, such as cargo ships, passenger ships, fishing boats, etc.. Especially important is that it has excellent fireproof performance, which can effectively protect the safety of ships during navigation. These marine cables provide reliable support for the stable operation of ships. If you are looking for a marine cable supplier, Jiangnan Cable is your best choice as a top power cable/specialty cable manufacturer in China.

Short circuit current ratings

1. The following short current ratings are for cables normally operating at a maximum

conductor temperature of 90℃

2. As a basis of the calculation,the theoretical temperature that arises in the conductor

during a short circuit is 250℃ in accordance with IEC60724.

3. EPR insulation are capable of withstanding of short term temperature up to 250℃

4. The short circuit current rating for copper conductors given in the table are values for 1

sec.and for other duration the current may be calculated by the following formular;

	lt: Short circuit current fort second (A)
	l1: Short circuit current for 1 second (A)
	t: Short circuit duration(second )

5. The duration of short circuit based on these assumptions should be between 0.2 sec

and 5 sec

2. Pulling tension

The cable puling tension during installation can be estimated through the following formula:
