Abstract
The invention discloses a reinforced flexible cable of shore power for a ship. The reinforced flexible cable comprises a cable core which is composed of a plurality of insulating cable cores in a twisting mode; each insulating cable core is composed of a fan-shaped conductor and a low-dielectric loss insulating layer extruded outside the conductor; a wrapping tape layer winds the cable core, and an outer sheath is extruded outside glass fiber; a reinforced saddle type support strip capable of stabilizing the whole structure of the cable is arranged in the cable core, and high-intensity aramid yarn is arranged at the center of the reinforced saddle type support strip; a polytetrafluoroethylene dope layer is sprayed to each of two lateral surfaces of the reinforced saddle type support strip and the outer surfaces of the insulating layers. The reinforced flexible cable of the shore power for the ship solves the disadvantages of large overall bending degree of a fan-shaped conductor cable and heavy weight of a round conductor cable and combines the advantages of the two cables so as to realize the light weight, small volume and small bending degree; the reinforced flexible cable of the shore power for the ship is more suitable for the ship.
Description
Technical field
The invention belongs to power cable field, be specifically related to reinforced bank electricity flexible cable for a kind of naval vessel.
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.And the shore connection cable insulation and the sheath that use at present all adopt elastomeric material, its conductor roughly has two kinds, a kind of be employing be circular configuration conductor, another kind is exactly to adopt sector structure conductor.
Problem and shortcoming that prior art exists:
Shore connection cable adopts circular configuration conductor, have good bending property, but its weight and volume is all larger, inconvenient personnel's operation; Another kind is exactly to adopt sector structure conductor, and such cable is lightweight, and volume is little, although facilitate personnel to pull, it adopts peculiar fan-shaped structure, and its flexibility is large, is in use inconvenient to operate.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide that a kind of quality is light, volume is little, flexibility is little, softness is good, the reinforced bank electricity flexible cable that is more suitable for using on naval vessel.
Reinforced bank electricity flexible cable for a kind of naval vessel of the present invention, comprises cable core, and cable core is by some stranded the forming of insulated wire cores; Insulated wire cores is made up of sector conductor and the low dielectric loss insulating barrier that is extruded in outside conductor; The outer wrapped belting layer of cable core, glass fiber tape extrudes oversheath outward; In described cable core, be provided with the integrally-built reinforced saddle type support bar that can stablize cable, this reinforced saddle type support bar center is provided with high strength aramid yarn; Described reinforced saddle type support bar both side surface and insulating barrier outer surface are all coated with teflon coating layer.
Further improve, described belting layer adopts glass fiber tape.
Further improve, described sector conductor adopts the mode of bundle strand in the same way, reduces bundle strand pitch simultaneously, and its bundle strand pitch is in 10 times.
Further improve, the stranded lay ratio of described insulated wire cores is controlled in 8-10 times.
Beneficial effect of the present invention is:
In cable conductor, be provided with reinforced saddle type support bar, polytetrafluoroethylene is sprayed on reinforced saddle type support bar surface by the mode in saddle type support bar both sides by electrostatic spraying, is also coated with at fan-shaped surface of insulating layer simultaneously; Polytetrafluoroethylene can make elastomeric material surfaces reduce friction coefficient, and the characteristic of polytetrafluoroethylene can be not influenced because of the situation of HTHP in processing cable process yet.Therefore in the time of cable bend, core and reinforced saddle type support bar can produce relative displacement, thereby the bending radius of cable is diminished.Reinforced saddle type support bar can be stablized the overall structure of cable simultaneously; and the middle high strength aramid yarn of reinforced saddle type support bar is positioned at cable bosom; make to bear in BENDING PROCESS maximum power; thereby protection sector conductor structure; it is high that reinforced aramid yarn has intensity; the feature that density is little, is used it also to alleviate the weight of cable.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, reinforced bank electricity flexible cable for a kind of naval vessel of the present invention, comprises cable core, and cable core is by some stranded the forming of insulated wire cores; Insulated wire cores is made up of sector conductor 1 and the low dielectric loss insulating barrier 2 that is extruded in outside conductor 1; The outer wrapped belting layer 3 of cable core, the outer oversheath 4 that extrudes of belting layer 3; In described cable core, be provided with the integrally-built reinforced saddle type support bar 5 that can stablize cable, these reinforced saddle type support bar 5 centers are provided with high strength aramid yarn 6; Described reinforced saddle type support bar 6 both side surface and insulating barrier outer surface are all coated with teflon coating layer 7.
Operation principle of the present invention:
The flexibility that can reach round conductor for realizing sector conductor bank electricity flexible cable, mainly realizes from following two aspects:
1, in sector cable, be provided with reinforced saddle type support bar, polytetrafluoroethylene is sprayed on reinforced saddle type support bar surface by the mode in saddle type support bar both sides by electrostatic spraying, has at fan-shaped insulated wire cores surface spraying simultaneously.Polytetrafluoroethylene can make elastomeric material surfaces reduce friction coefficient, the characteristic of polytetrafluoroethylene can be because not affected by the situation of HTHP in processing cable process yet, therefore in the time of cable bend, core and reinforced saddle type support bar can produce relative displacement, thereby the bending radius of cable is diminished.Simultaneously reinforced saddle type support bar can stablize the overall structure of cable, and the high strength aramid yarn of reinforced saddle type support bar centre is positioned at cable bosom, makes to bear in BENDING PROCESS maximum power, thereby protects sector conductor structure.It is high that reinforced aramid yarn has intensity, and the feature that density is little is used it also to alleviate the weight of cable.
2, conductor, cable core stranded mode on also can realize and reduce bending radius by reducing twisting pitch, its specific practice is: sector conductor adopts and restraints in the same way strand mode, reduces bundle strand pitch simultaneously, bundle strand pitch is in 10 times; Cable core stranded aspect, the stranded lay ratio of insulated wire cores be controlled at 8-10 doubly in.
The invention provides reinforced bank electricity flexible cable for a kind of naval vessel; the above is only preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improve and also should be considered as protection scope of the present invention.
