Description
Technical field
The utility model relates to a kind of high conductivity power cable, belongs to power cable technical field.
Background technology
The diameter of electric power cable, directly have influence on the payload capability that electric power cable can bear, in general, the diameter of electric power cable is larger, its electric energy load that can bear is also larger, but find in actual use, when transmitting alternating current, in conductor, because of " kelvin effect ", electric current often occurs that current convergence is distributed in conductor top layer, then little by electric current in the middle part of conductor, thus cause power cable ability to transmit electricity and load capacity to decline, and the drawback that caloric value increases, and along with the negative effect of the increase kelvin effect of cable size also larger, simultaneously, presently used cable mostly is solid construction and joins one or more tension rope, therefore cause its area of dissipation relatively little, and tension and ability of anti-deformation are also relatively poor, load capacity and the usage safety performance of power cable are had a strong impact on, simultaneously due to its tension and ability of anti-deformation deficiency, when carrying out unsettled erection, also easily there is the sagging serious phenomenon of cable, therefore need increasing design cable power transmission ability and opposing kelvin effect being carried out necessity to traditional cable structure.
Summary of the invention
The utility model object is just to overcome above-mentioned deficiency, provides a kind of high conductivity power cable.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of high conductivity power cable, cable core conductor is by insulating barrier, conductor and tension element are formed, wherein conductor is hollow pipe assembling structure, conductor outside surfaces establishes at least one groove, groove and conductor axis being parallel, and groove wall thickness and conductor wall thickness identical, and groove depth capacity is not more than 1/3 of the monolateral maximum length of cross-sectional area of conductor, Breadth Maximum is greater than 1/4 of cross-sectional area of conductor maximum perimeter, tension element is embedded in the hollow position of conductor and the recessed grain of outer surface, and and isolated by insulating protective layer between conductive surface, conductor hollow position its sectional area of tension element is not more than 5/6 of conductor hollow section area, at least one mesopore is separately established in tension element, mesopore and conductor axis being parallel, the mesopore cross section gross area is not more than 1/4 of the tension element cross section gross area, insulating barrier is coated on outside conductor, and separately establish elastic protection layer between insulating barrier and conductor.
Tension element is elastic caoutchouc.
Tension element and elastic protection layer are nylon fiber braid or cotton fiber braid.
Conductor maximum ga(u)ge is not more than 100 millimeters.
Insulating protective layer is elastic insulating material.
Centered by conductor effective cross-sectional area, the 1-5 of cavity cross section area doubly.
Separately set up defences in insulating barrier and protect armour.
The more traditional cable of the utility model effectively reduces the ubiquitous collection skin of cable conductor and imitates the drawback brought, simultaneously the utility model also effectively raises the tension of cable, impact resistance and heat-sinking capability, cable self structure intensity is also improved greatly, enhance the sagging ability of antigravity, from further increasing the ability to transmit electricity of cable, load capacity, damage-retardation ability and stability in use.
Accompanying drawing explanation
Fig. 1 is side plate partial enlarged drawing.
Embodiment
A kind of high conductivity power cable as shown in Figure 1, cable core conductor is by insulating barrier 6, conductor 1 and tension element 2 are formed, wherein conductor 1 is hollow pipe assembling structure, conductor 1 outer surface establishes at least one groove 3, groove 3 and conductor 1 axis being parallel, and groove 3 wall thickness and conductor 1 wall thickness identical, and groove 3 depth capacity is not more than 1/3 of the monolateral maximum length in conductor 1 cross section, Breadth Maximum be greater than conductor 1 cross section maximum perimeter 1/4 described in tension element 2 be embedded in the hollow position of conductor 1 and outer surface recessed poor 3, and and isolated by insulating protective layer 4 between conductor 1 surface, conductor 1 hollow position its sectional area of tension element 2 is not more than 5/6 of conductor 1 hollow section area, at least one mesopore 5 is separately established in tension element 2, mesopore 5 and conductor 1 axis being parallel, the mesopore 5 cross section gross area is not more than 1/4 of the tension element 2 cross section gross area, described insulating barrier 6 is coated on outside conductor 1, and separately establish elastic protection layer 7 between insulating barrier 6 and conductor, separately set up defences in insulating barrier 6 and protect armour 8.
Now with a kind of active conductor area of section for 20mm2 cable, because use occasion is underground preburied cable laying, and need repeatedly to turn and reserved at least two circle cables are example, the utility model be further described:
Because environment for use requires that cable has good bending property, so conductor adopts hollow circular-tube class formation, its conductor effective cross-sectional area is 20mm2, middle cavity area of section is 15mm2, uniform 4 grooves on conductor outer wall, groove Breadth Maximum is its hollow core position its sectional area of tension element is 8 mm2, 4 interspace holes are established in tension element, mesopore total cross-sectional area is 2 mm2, nylon fiber protective layer is established between another conductor and tension element, wherein tension element material is also nylon material, establish elastic caoutchouc mesh sheet as insulating protective layer between conductor and insulating barrier, another embedding protection steel armour in outer insulation, and steel armour is 1 millimeter by thickness, width 5 mm band steel is entwined.
