Problems solved by technology

[0005] 1. There are only power core wires, which only have the function of power transmission;
[0006] 2. There is an insulating layer directly outside the core wire conductor, and the electromagnetic shielding effect is general;
It also does not solve the problems of single function and general electromagnetic shielding effect.

Abstract

The invention relates to a cable, and particularly relates to a marine shore power cable which is especially suitable for a ship being connected with shore power or a ship. The marine shore power cable comprises three main wire cores (5), a ground wire core (8), an optical communication transmission unit (11), a plurality of control wire cores (14) and fillers (15), wherein the main wire cores (5), the ground wire core (8), the optical communication transmission unit (11), the plurality of control wire cores (14) and the fillers (15) are twisted into a cable core (16); an inner protective sleeve (17) is closely wrapped on the cable core (16); and the inner protective sleeve (17) is sequentially provided with a braiding layer (18) and an outer protective sleeve (19). After the technical scheme is adopted, the marine shore power cable is diverse in function and wide in application range, and has multiple functions, such as power transmission, communication, and the like.

Description

technical field [0001] The invention relates to a cable, in particular to a shore power cable for ships. The present invention is especially suitable for the cable connecting the ship to the shore or the cable for the ship. The invention belongs to the field of power cables. Background technique [0002] The existing ship-to-shore power cables or ship-use power cables only have a single power transmission function. In order to achieve control and communication requirements, additional ship-use control cables and communication cables need to be laid. The existing technology cannot effectively integrate the power transmission network, telecommunication network, radio and television network, and the Internet into multiple networks, and cannot meet the requirements of an intelligent ship control system. [0003] For example, Chinese patent announcement number CN2736894Y discloses a shore power cable for ships, which includes three core wire conductors arranged on the innermos...
