Description

Technical Field

[0002] Large ships usually use heavy oil or diesel to generate electricity when arriving at the port to meet the electricity needs of the ship when it is docked. As the call for low-carbon emission reduction in my country becomes louder and louder, some ports have begun to provide shore power technology for docked ships. Therefore, special cables for ships are needed to ensure the power supply needs of ships when they are docked.

[0003] Existing special cables for ships are often used after directly wrapping multiple layers of rubber protective layers on the outside of the cable core. However, after the ship docks, the position of the ship is often not fixed, and the shaking of the ship may cause collision with the cable, and existing cables are often difficult to effectively protect the cable core. At the same time, during the shaking of the ship, the cable on the ship connected to the ground may bend or stretch, and the cable core and the rubber protective layer on its outside are often unable to withstand the tension generated by the ship on the cable, and the bending of the cable will also cause damage to the cable core, thereby affecting the use effect of the entire special cable for ships.
