Description
Technical field
The utility model relates to a kind of photoelectric compound cable of large size conductor.
Background technology
At present, the conductor thread core more than 90% of China's power cable all adopts copper conductor material, and wherein the supply of COPPER IN CHINA is less than 30%, therefore a large amount of import is needed, this not only wastes the limited foreign exchange of country, and copper conductor makes the Heavy Weight of cable, and design library part editor and reuse and cost of transportation are also higher.Offshore wind farm domestic at present, novel environment friendly direct current cables all face larger development and adjustment, the quickening of urbanization rhythm in addition, the central and west regions temperature difference is large, span large, distance, cable also has very large development space, therefore urgently has a kind of cable that can reduce costs to carry out alternative copper conductor cable.
Utility model content
The purpose of this utility model is to overcome the defect of prior art and provides a kind of photoelectric compound cable of large size conductor, and it can not only reduce material cost, and design library part editor and reuse and cost of transportation can also be made to be reduced.
The purpose of this utility model is achieved in that a kind of photoelectric compound cable of large size conductor, comprises cable core, semi-conductive buffer layer, two optical cable component wires; Wherein,
Described cable core is five divided aluminum conductors of 1 core and sectional area is 1200mm2;
Described semi-conductive buffer layer is arranged on the periphery of cable core;
Two described optical cable component wires are arranged on the two ends of the same diameter line along described semi-conductive buffer layer correspondingly, and the both sides of these a two optical cable component wires difference wrapped stainless steel wire side by side;
Enhancement layer, internal shield, insulating barrier and outer shielding layer is also set gradually between described cable core and described semi-conductive buffer layer;
Described semi-conductive buffer layer also sets gradually semiconductor waterstop, aluminium sheath, oversheath and graphite linings outward.
The photoelectric compound cable of above-mentioned large size conductor, wherein, described enhancement layer is that wrapped semiconductive outside described cable core blocks water binding strap.
The photoelectric compound cable of above-mentioned large size conductor, wherein, described optical cable component wire is 4 core multimode optical cables.
The photoelectric compound cable of above-mentioned large size conductor, wherein, the material of described oversheath is crosslinked polyethylene.
The photoelectric compound cable tool of large size conductor of the present utility model has the following advantages:
1., under the prerequisite meeting same electrical performance, the weight of aluminum conductor cable only has the half of identical ampacity copper conductor cable;
2., because cable weight significantly alleviates, design library part editor and reuse and cost of transportation are reduced;
3., because aluminum conductor cable is lightweight, decrease the material requirements of cable stationary barrier, bridge support;
4. energy on-line checkingi cable operating temperature and communication, ensures cable running safety.
Accompanying drawing explanation
Fig. 1 is the sectional view of the photoelectric compound cable of large size conductor of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
First refer to Fig. 1, the photoelectric compound cable of large size conductor of the present utility model, comprise cable core 1, semi-conductive buffer layer 6, two optical cable component wire 7; Wherein:
Cable core 1 is five divided aluminum conductors of 1 core and sectional area is 1200mm2;
Semi-conductive buffer layer 6 is arranged on the periphery of cable core 1;
Enhancement layer 2, internal shield 3, insulating barrier 4 and outer shielding layer 5 is also set gradually between cable core 1 and resilient coating 6; Enhancement layer 2 is that wrapped semiconductive outside cable core 1 blocks water binding strap;
Two optical cable component wires 7 are arranged on the two ends of the same diameter line along semi-conductive buffer layer 6 correspondingly, and the both sides of these a two optical cable component wires 7 difference wrapped stainless steel wire 70 side by side;
Semi-conductive buffer layer 6 is outer also sets gradually semiconductor waterstop 7, aluminium sheath 9, oversheath 10 and graphite linings 11; The material of oversheath 10 is crosslinked polyethylene.
The photoelectric compound cable of large size conductor of the present utility model, optical cable component wire 7 wherein for optical cable component wire be 4 core multimode optical cables, be arranged on the surface of resilient coating 6, for on-line checkingi temperature with for communication, be convenient to photoelectric compound cable in running, the temperature that on-line checkingi photoelectric compound cable runs and communication, safe and reliable when ensureing that photoelectric compound cable runs.The effect of stainless steel wire 70 is the intensity strengthening cable core 1, plays the effect of ground connection simultaneously, prevents short circuit.
The photoelectric compound cable of large size conductor of the present utility model; the function playing insulative water-proof is functionally needed at endothecium structure; especially enhancement layer 2, internal shield 3, insulating barrier 4, outer shielding layer 5 and resilient coating 6; therefore these protective layers all adopt the material of insulation, waterproof in the selection of material; and structurally fit tightly, consider the infiltration of anti-sealing from material, structure two aspect simultaneously.On layer structure, major design considers the function of antidetonation, anti-shearing force, therefore adopts aluminium sheath 9, oversheath 10 and graphite linings 11, forms an overall structure, make cable insulation not easy damaged, meet various service condition and environmental requirement.Oversheath 10 adopts crosslinked polyethylene to make, and makes cable allow working temperature can reach 90 DEG C for a long time.To keep elastic stage at 130 DEG C of temperature, relatively with prismatic polyvinyl chloride cable, its combined closure system can improve about 25%.
The photoelectric compound cable of large size conductor of the present utility model, because the cross section of conductor is comparatively large, therefore must adopt milliken conductor, to reduce the impact of AC resistance increase on transmission capacity that " kelvin effect " and " proximity effect " causes the conductor of cable.Therefore when milliken conductor, adopt the pinch roller in three directions, solve the problem that milliken conductor external diameter is large.
Due to aluminium conductor weight aspect comparatively copper conductor have superiority, therefore certain superiority is also had at design library part editor and reuse and reduction transport fund aspect, along with human cost improve constantly and the requirement of engineering project to the duration more and more tighter, the appearance of aluminum conductor cable has just in time adapted to this demand, because cable weight significantly alleviates, decrease the requirement of the material such as cable stationary barrier, bridge support, under the prerequisite meeting same electrical performance, the weight of aluminum conductor cable only has the half of identical ampacity copper conductor.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
