Description
Technical field
The utility model is related to a kind of cable, and especially a kind of reinforced high voltage shore power cable, belongs to field of cable technology.
Background technology
When harbour is reached due to need of work and living needs, ship needs to use electric power to ensure large ship,
Obtaining electric power on usual ship mainly has two ways：
1st, using the generating equipment that ship is self-contained, use during vessel berth is met using heavy oil or diesel generation
Electric demand；
2nd, bank electricity is transmitted to ship using cable for ship, it is small to adopt environmental pollution in this way, can fully use
Electric power resource.
The problems and disadvantages that prior art is present are as follows：
When the 1st, using heavy oil or diesel generation, carbon monoxide, unburned hydrocarbon, nitrogen oxide etc. can be produced
There is the gas of pollution to air, effect on environment is very big；
2nd, the structure of common cable for ship is the outer extruded insulation of conductor, after being then twisted into cable core, in cable core outer wrapped
Layer polyester belt, last extrude sheath；The type cable has polyester belt due to insulating with the middle of sheath, in long-term retractable volume in,
Insulation and the easy displacement of sheath, cause bulge phenomenon, there is no any reinforcement structure in the construction of cable in addition, long-term retractable volume around
In easily damage cable conductor.And cable for ship restrictive coating is relatively thin, when with hull, ground friction, cable is easily damaged, it is long
Phase use can influence the service life of cable.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of reinforced high voltage shore power electricity
Cable, can solve the problem that in the prior art shore connection cable intolerant to pull and easily there is the problem of bulge.
According to the technical scheme that the utility model is provided, the reinforced high voltage shore power cable, including cable core, its feature
It is：The cable core by centrally-disposed reinforcement rope and around strengthen three power wire cores that rope excircle arranges it is stranded and
Into；Inner sheath is extruded outside the cable core, aramid yarn enhancement layer is woven outside inner sheath, outer shield is extruded outside aramid yarn enhancement layer
Set.
Further, the power wire core includes power wire core conductor, and power line is set gradually outside power wire core conductor
Screen layer, power wire core insulating layer of conductor and power wire core conductor external screen layer, compile outside power wire core conductor external screen layer in core conductor
Knit power wire core metal screen layer.
Further, the reinforcement is restricted includes that high intensity aramid fiber strengthens rope, is extruded on the outside of the reinforcement of high intensity aramid fiber is restricted and added
Strong rope packed layer.
Reinforced high voltage shore power cable described in the utility model, the structure being integrated using power wire core, retractable volume around
In be not in bulge phenomenon；Reinforcement structure is added in the middle of the center of cable and sheath in addition, cable is substantially increased whole
The resistance to dragging performance of body.
Brief description of the drawings
Fig. 1 is the structural representation of reinforced high voltage shore power cable described in the utility model.
Description of reference numerals：1- high intensity aramid fiber strengthens rope, 2- and strengthens rope packed layer, 3- power wire cores conductor, 4- power
Screen layer, 5- power wire cores insulating layer of conductor, 6- power wire core conductors external screen layer, 7- power wire core metallic shields in cable core conductor
Layer, 8- inner sheaths, 9- aramid yarns enhancement layer, 10- oversheaths.
Specific embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As shown in figure 1, reinforced high voltage shore power cable described in the utility model includes cable core, cable core is by centrally disposed position
The reinforcement rope put and stranded formed around three power wire cores for strengthening rope excircle arrangement；Shield in directly being squeezed outside the cable core
Set 8, in the outer braiding aramid yarn enhancement layer 9 of inner sheath 8, extrudes oversheath 10 outside aramid yarn enhancement layer 9.
The power wire core includes power wire core conductor 3, will be dynamic by the way of three-layer co-extruded outside power wire core conductor 3
Screen layer 4, power wire core insulating layer of conductor 5 and power wire core conductor external screen layer 6 are disposably extruded in line of force core conductor, then in power
The outer braiding power wire core metal screen layer 7 of cable core conductor external screen layer 6.
The rope of strengthening includes that high intensity aramid fiber strengthens rope 1, and strengthening the outside of rope 1 in high intensity aramid fiber extrudes reinforcement rope filling
Layer 2.
Operation principle of the present utility model：
1st, bulge phenomenon is solved：
Because cable needs long-term retractable volume around, common cable for ship due to insulation and sheath adhesion, in long-term folding and unfolding
Easily there is the phenomenon of bulge in winding process.In order to solve problems, the utility model is closely squeezed using the embedding gap of inner sheath 8
Bag is in power wire core.Because power wire core is structure as a whole, in folding and unfolding winding process, position will not occur inside power wire core
Move, solve bulge phenomenon.
2nd, resistance to dragging principle：
The bosom of cable is the region that stress is most concentrated, and a reinforced virtue is provided with the bosom of cable
Synthetic fibre rope, stress is concentrated on reinforcement aramid fiber rope, so as to protect the conductor of cable.
Cable cover(ing) structure is " interior shield+enhancement layer+outer shield ", i.e. inner sheath 8, aramid yarn enhancement layer 9, oversheath 10,
The aramid fiber enhancement layer set in interior oversheath improves cable dragging performance.
The mode that this two groups of reinforcement structures are combined from inside to outside improves cable integrally resistance to dragging performance.
