Abstract
The invention discloses a shore power cable for a ship. The shore power cable comprises a cable core. The cable core is formed by stranding a plurality of wire cores in parallel. A gap of the cable core is filled with stuffing, an inner jacket is extruded outside the cable core, and an outer jacket is extruded on the outermost layer. A light high-strength material reinforcing layer is woven between the inner jacket and the outer jacket. The shore power cable has the advantages of being low in dielectric loss, good in bending performance, light in weight, capable of resisting abrasion and the like, and the service life of the shore power cable is also greatly prolonged.
Description
Technical field
The present invention relates to electric wire field, especially a kind of by the delivery of electrical energy on harbour to the shore connection cable using on boats and ships.
Background technology
The effect of shore connection cable is during ship berthing, not use electric set electric supply, but adopt by shore connection cable, bank fax is passed to power supply use on ship, plays transmitting effect.The naval vessel shore connection cable using is at present CEFR/SA type, i.e. ethylene propylene rubber insulated, chloroprene rubber sheath, bunchy flame retardant type flexible electric power cable peculiar to vessel.And such cable is mainly used on boats and ships being used as electric power transfer, such cable has higher fire resistance.
Problem and shortcoming that prior art exists:
Shore connection cable is twisted on cable reel in the time not using; in the time of use procedure, cable is pulled on ship and is used; therefore such cable often has towing; the actions such as reel; and in use, also frequent meeting and hull, ground rubs; and existing CEFR/SA type shipboard cable does not have resistance to towing, reel function.CEFR/SA type cable is to design for the alternating current system of cable 50Hz, due to the difference (boats and ships of external many countries adopt the alternating current system of 60Hz) of at present domestic and international alternating current system, such cable is used in can be serious because of dielectric loss on external boats and ships, and affect the useful life of cable.
Summary of the invention
The present invention provides one to have the features such as dielectric loss is low, wear-resisting, good bending property, lightweight for the problem that solves prior art and exist, and the shore connection cable for ship greatly improving useful life.
For solving above technical problem, a kind of shore connection cable for ship of the present invention, comprises cable core, and this cable core is by many cores stranded forming side by side, and cable core gap is filled with filler, and cable core extrudes inner sheath outward, and outermost layer extrudes oversheath; Between inner sheath and oversheath, weave light high-intensity material reinforced layer.
Further improve, described core is made up of zinc-plated flexible conductor and the low dielectric loss insulating barrier that is extruded in outside zinc-plated flexible conductor.
Compared with prior art, beneficial effect of the present invention:
1, the present invention adopts low dielectric loss insulating material, can, because the difference of alternating current system makes the dielectric loss of cable serious, not make electric energy loss in course of conveying serious like this;
2, cable conductor of the present invention and inner sheath adhesion, in wrapup procedure, cable core can not be subjected to displacement, and is applicable to cable reel and uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated:
As shown in Figure 1, a kind of shore connection cable for ship of the present invention, comprises cable core, and this cable core is by many cores stranded forming side by side, and cable core gap is filled with filler 3, and cable core extrudes inner sheath 4 outward, and outermost layer extrudes oversheath 6; Between inner sheath 4 and oversheath 6, weave light high-intensity material reinforced layer 5.Described core is made up of zinc-plated flexible conductor 1 and the low dielectric loss insulating barrier 2 that is extruded in outside zinc-plated flexible conductor 1.
The operation principle of such cable or the course of work:
Shore connection cable uses on different at home and abroad boats and ships, due to the alternating current difference processed of various countries, therefore in such cable, adopt low dielectric loss insulation, adopt such insulation can avoid cable because dielectric loss seriously makes the many situations of electric energy loss, and can increase the useful life of cable.Shore connection cable needs frequent rolling to winch, and therefore the distortion performance of cable is also one of important requirement of cable.The copper wire that cable adopts is five class tinned copper wires, but compared with common, the filament diameter of such copper wire is less than common filament diameter, conductor copper wire radical with cross section is more, adopts and can make in this way the bending property of cable better, and the cable core of cable protects in being extruded with outward simultaneously, inner sheath and insulated wire cores adhesion, cable conductor can not be subjected to displacement, there is good bending property, and rolling number of times is higher than CEFR/SA type.
Above-mentioned is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement and adjustment, these improvement and adjustment also should be considered as protection scope of the present invention.
