Flexible tensile optical fiber composite shore connection cable

Abstract

The invention relates to a flexible tensile optical fiber composite shore connection cable which comprises a cable core formed by mutually stranding a plurality of wire cores, wherein the wire cores comprise conductors; isolation layers are arranged outside the conductors; insulation layers are used for wrapping the isolation layers in a pressing manner; the insulation layers are provided with semi-conductive wrapping layers; a combination body comprising a plurality of control wire cores and an optical communication unit is arranged in the center of the cable core; an inner sheath is used for wrapping the cable core in a pressing manner; an aramid yarn inner reinforcing layer is woven outside the inner sheath; a high-intensity chlorinated polyethylene outer protection layer is used for wrapping the reinforcing layer in a pressing manner; a wrapping layer and an outer reinforcing layer are arranged outside the outer protection layer. The flexible tensile optical fiber composite shore connection cable has good comprehensive performance of easiness in bending, torsion resistance, tear resistance, wave resistance, salt mist resistance, high corrosion resistance, excellent long-term water soaking electrical property, easiness in stripping and portability.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a tensile-resistant optical fiber composite flexible shore power cable. Background technique [0002] At present, my country's ships calling at ports usually use auxiliary engines to generate electricity to meet the power needs of refrigeration, air conditioning, heating, communication, lighting, etc. on board. However, the auxiliary engine of the ship is a fuel generator. During the process of fuel consumption, a large amount of air pollutants such as nitrogen oxides and sulfur oxides will be emitted, which will affect the environmental quality of the port and the city where it is located. Many developed countries or regions have already required ships calling at ports to use shore power to reduce the use of auxiliary engines for ships calling at ports. If developed countries or regions require ships calling at ports to use shore power, the emissions of nitrogen oxides, sulfur d...

AI Technical Summary

Problems solved by technology

[0006] 1. Only the power core wire, only has the function of power transmission;

[0007] 2. Average tensile and tear resistance properties;

[0008] 3. The cable is braided with light fiber material, the electromagnetic shielding effect is average, and the cable anti-interference performance is poor;

Although it solves the integration of power and communication, it also has problems such as general electromagnetic shielding effect, poor cable anti-interference performance and general tensile and tear resistance performance.
