Submarine cables are laid on the seabed, the use environment is relatively severe, and the safe use of the cables can be guaranteed only by more comprehensive protection. In order to improve protection of the submarine cable, a protective sleeve or a protective layer is usually arranged outside the cable for protecting the cable, but due to the harsh submarine environment, the protective sleeve is not only washed and corroded by seawater, but also can be invaded by submarine animals, so that the protective sleeve is easy to damage, and once the protective sleeve is damaged, the protective effect is greatly reduced, so that the protective sleeve needs to be inspected, and the damage of the protective sleeve is discovered.

The submarine cable for offshore wind power in the prior art needs to be checked in detail along the cable when the protective sleeve of the submarine cable is inspected, and the protective sleeve is very troublesome to inspect and low in efficiency due to the fact that the submarine cable is difficult and dangerous to operate. Therefore, we propose a submarine cable for offshore wind power suitable for use in shallow sea areas.
