Description

A kind of flexibility tension Optical Fiber Composite shore connection cable

Technical field

This utility model is related to field of cable technology, more particularly, to a kind of Optical Fiber Composite flexibility bank electricity electricity being capable of tension Cable.

Background technology

At present, ship is reached port generally using subsidiary engine generating in China, to meet cold preservation on ship, air-conditioning, heating, communication, illumination Etc. electricity needs.However, marine auxiliary is fuel electric generator, during fuel consumption, substantial amounts of nitrogen oxidation can be given off The air pollutants such as thing, oxysulfide, impact harbour and place The Surroundings in Cities quality.Already in many developed country or region Seek refuge with port ship and use bank electricity, reduce the ship that reaches port and use subsidiary engine.If developed country or region requirement is reached port, ship uses bank Electricity, the discharge capacity of the nitrogen oxides at harbour, sulfur dioxide and pellet PM10 will greatly reduce.Produce with harbour and lead The air pollution causing increasingly is subject to social concerns, and harbour energy-saving and emission-reduction, green low-carbon are not only policy requirements, even more real institute Become.

Spot ship connects the cable single varieties of bank electricity, and structure design is unreasonable, and combination property is poor, and does not enable many The intelligent ship control system that net merges.

Shore power cable for ship as disclosed in Chinese patent notification number CN201410049656.2 and CN201520185004.1, Its structure is similar to be all including three cored wire conductors being arranged at innermost layer, is equipped with insulating barrier outside each cored wire conductor, three It is surrounded with lapping layer, lapping layer is externally provided with sheath, braiding layer and outer jacket, described insulation outside cored wire conductor with insulating barrier It is provided with packed layer between layer and between lapping layer and insulating barrier, be connected outside described packed layer.

The main deficiency of two patents：

1, only electric power heart yearn, only there is power transmission function；

2, tension, tear resistance are general；

3, the light-duty fibrous material of cable braid, effectiveness is general, and cable anti-interference is poor；

For another example Chinese patent notification number CN201510537811.X discloses a kind of light-duty combined type shore connection cable, in cable core Centrally disposed rubber saddle type bar, rubber saddle type bar center is provided with a circular groove and is provided with optical fiber, is provided with three etc. centered on circular groove Away from groove, rubber saddle type bar edge is provided with three identical half slots and is provided with power wire core in half slot；Outside cable core Extrude chlorosulfonated polyethylene inner sheath, weave high intensity aramid yarn outside chlorosulfonated polyethylene inner sheath, extrude chlorine in outermost layer Sulfonated polyethylene oversheath.Although it solves electric power, communication one, equally exist effectiveness typically, cable resists The problems such as interference difference and tension, tear resistance are general.

In sum, it is truly realized flexible, anti-torsion, anti tear, wind and wave resistance, salt spray resistance, corrosion-resistant height, long-term soak Excellent electrical property, corrosion-resistant, be easily peeled construction and light combination property, union electric power, control, be in communication in the bank peculiar to vessel of one Electrical cables are it is still necessary to improve.
