Abstract

The invention discloses a three-core cable used for a vessel. The three-core cable comprises a center reinforcement part which is composed of fiber glass filament bundles and located in the center. A first conductor, a first isolation body, a second conductor, a second isolation body, a third conductor and a third isolation body are arranged on the periphery of the center reinforcement part, tightly attached to the center reinforcement part and sequentially connected. A first cavity, a second cavity and a third cavity are formed in the first isolation body, the second isolation body and the third isolation body respectively. The peripheries of the first conductor, the second conductor, the third conductor, the first isolation body, the second isolation body and the third isolation body are wrapped with a coating layer formed by wrapping an aluminum plastic composite strip in a wound mode. A waterproof layer is arranged on the periphery of the coating layer, a protective outer sleeve is arranged on the periphery of the waterproof layer, and an armor layer is arranged between the waterproof layer and the coating layer and formed by wrapping the coating layer with multiple inclined aluminum wires in a wound mode. A tin metal layer is arranged between the coating layer and the armor layer. The three-core cable used for the vessel is simple in structure, good in flexibility, high in anti-interference capacity, good in corrosion resistance and convenient to drag.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a three-core cable for ships. Background technique [0002] At present, all countries in the world are constantly strengthening the development and utilization of marine resources. Ships, as the main means of transportation and transportation in the ocean, have been rapidly developed and widely used, and the demand for ships' cables has also increased rapidly. Due to the large number of instruments on the ship, it is necessary for the cable for the ship to have good anti-interference ability. At the same time, the erosion of seawater and sea fog in the marine environment also puts forward higher requirements for the corrosion resistance of the cable for the ship. In the prior art, in order to improve the anti-interference and anti-corrosion capabilities of the cables, the number of shielding layers and the anti-corrosion properties of the materials are usually increased, res...
