Novel cable for shore power system

Abstract

The invention relates to a novel cable for a shore power system. The cable comprises conductors, isolating layers, insulating layers, a center pad core, an integrated inner pad layer, a non-metallic reinforcing fiber layer and an outer sheath, wherein each conductor is sequentially provided with each isolating layer and each insulating layer to form an insulated wire core; a plurality of insulated wire cores are twisted with one another to form a cable core; the center pad core is arranged at the center of the cable core; the plurality of insulated wire cores are equally arranged at the outer side of the center pad core; the integrated inner pad layer extrudes and wraps the surface of each insulated core wire and the adjacent gap; and the non-metallic reinforcing fiber layer and the outer sheath are sequentially arranged at the outer side of the integrated inner pad layer. The novel cable for the shore power system is compact in structure, light in weight, bending resistant, good in flexibility, dragging resistant, environment-friendly, nontoxic and good in flame retardant property.

Description

technical field [0001] The invention relates to a cable, in particular to a novel cable for a shore power system. Background technique [0002] The so-called shore power system means that the ship does not use the ship's generator set but is powered by the shore power supply during berthing. The shore power of the wharf supplies power to the electrical equipment on the ship through the ship's shore power connection cable and the shore power box, ensuring that the power demand of the ship's electrical equipment can be met. If a diesel generator is used for power supply when the ship is berthing, a large amount of sulfide and nitrogen oxides will be produced during the combustion of diesel, which will pollute the surrounding environment. According to the data of the International Maritime Organization (IMO): NOx and SOx are the main pollutants. The global diesel-powered ships emit 10 million tons of NOx and 8.5 million tons of Sox into the atmosphere every year; the pollutant...
