Description
Technical field
The utility model relates to field of cables, is specifically related to a kind of Novel composite cable.
Background technology
Existing cable, generally adopts copper wire as core, the aluminum steel of outer stranded circle.Mainly there is the problem of following several respects in this cable: one, due to skin stranded be circular aluminum steel, cause the gap of etween the lines large, net sectional area is little, and external diameter is large, store and transportation in take up room greatly.Two, uneven, rough by the stranded superficies that form of circular aluminum steel, easily pile up ice and snow or other heavy burden materials, increase the heavy burden of cable, anti-ice-snow ability, easily bends and destroys cable.Three, the tensile strength of copper wire used is low, and while setting up, span is less, sets up the required shaft tower quantity of cable many, and not only cost is large, wasting manpower and material resources, and also land occupation resource is many.Based on above problem, existing cable cannot meet the new demand of power construction fast development.
Utility model content
In view of this, the utility model aims to provide that a kind of ampacity is large, the Novel composite cable of anti-ice-snow function admirable.
In order to realize the purpose of this utility model, the utility model provides a kind of Novel composite cable, it comprises aluminum steel skin, aluminum steel internal layer and kernel line, described aluminum steel skin is by stranded the forming of fan-shaped aluminum steel of a plurality of distributions ringwise and close contact, described aluminum steel internal layer is distributed and stranded the forming of fan-shaped aluminium-clad steel wire of close contact ringwise by a plurality of, and described kernel line is arranged in the annular that described aluminum steel internal layer surrounds.
Preferably, described kernel line is circular aluminium-clad steel wire.
Preferably, in described kernel line, the radius of steel wire is greater than the radius of steel wire in the aluminium-clad steel wire of described aluminum steel internal layer.
Preferably, between described kernel line and described aluminum steel internal layer, be formed with gap.
Preferably, four jiaos of described fan-shaped aluminum steel and fan-shaped aluminium-clad steel wire all form arc angling.
Preferably, the cross-sectional area of described fan-shaped aluminum steel is greater than the cross-sectional area of described fan-shaped aluminium-clad steel wire.
Preferably, in described aluminum steel skin, the number of fan-shaped aluminum steel is greater than the number of fan-shaped aluminium-clad steel wire in described aluminum steel internal layer.
The Novel composite cable that the utility model embodiment provides, by being twisted into aluminum steel skin with fan-shaped aluminum steel, and be twisted into aluminum steel internal layer with fan-shaped aluminium-clad steel wire, and make this Novel composite cable have that ampacity is large, the feature of anti-ice-snow function admirable, therefore can in following electrical network, widely apply.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the Novel composite cable that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1, the utility model embodiment provides a kind of Novel composite cable, and it comprises aluminum steel skin, aluminum steel internal layer and kernel line 4.
Aluminum steel skin is by stranded the forming of fan-shaped aluminum steel 1 of a plurality of distributions ringwise and close contact, and for transferring electric power, indication aluminum steel can be aluminium alloy wire herein.Indication is fan-shaped herein, refers to that cross section is roughly covering of the fan shape, but not in how much defined " fan-shaped ".Use the stranded cable of fan-shaped aluminum steel, in the situation that cable requires net sectional area identical, than with little 20% left and right of the stranded outside diameter of cable of common round aluminum steel, ampacity has improved 60%.And, with fan type aluminum steel, can be twisted into a more completely circle, make the smooth outer surface of cable and closely, thereby make cable there is certain anti-ice-snow ability.
Aluminum steel internal layer is distributed and stranded the forming of fan-shaped aluminium-clad steel wire 2 of close contact ringwise by a plurality of, and kernel line 4 is arranged in the annular that aluminum steel internal layer surrounds.Indication aluminium-clad steel wire refers to the black part in steel wire 3(figure herein) outside be coated with aluminium, make it have good corrosion resistance.More than the intensity of aluminium Baogang monofilament has reached 1700MPA now simultaneously, suitable with the strength of galvanized wire of 4 grades of intensity, if developed than the aluminium Baogang monofilament of the less conductance of LB14, its tensile strength can be higher.The lifting of tensile strength has strengthened the weight capacity of cable core, thereby meets the requirement of large span, heavy in section, minor diameter overhead aluminum twisted wire, greatly reduces the shaft tower cost in new line construction, saves valuable land resource.Similarly, adopt fan-shaped aluminium-clad steel wire 2, make more closely rounding of cable core structure, external diameter compares with stranded 20% left and right that dwindles of circular aluminum steel.
In a preferred embodiment, kernel line 4 is circular aluminium-clad steel wire, makes cable core structure have higher intensity, to meet the requirement of strength of large span and large-cross section aerial aluminium stranded conductor.
In a preferred embodiment, in kernel line 4, the radius of steel wire 3 is greater than the radius of steel wire 3 in the aluminium-clad steel wire 2 of aluminum steel internal layer.
In a preferred embodiment, between kernel line 4 and aluminum steel internal layer, be formed with gap 5.Due to the existence in these gaps 5, make the self-damping effect of this Novel composite cable very excellent, can reduce in the overhead operated process of this Novel composite cable because of wind-induced vibration.
In a preferred embodiment, four jiaos of fan-shaped aluminum steel 1 and fan-shaped aluminium-clad steel wire 2 all form arc angling.
In a preferred embodiment, the cross-sectional area of fan-shaped aluminum steel 1 is greater than the cross-sectional area of fan-shaped aluminium-clad steel wire 2, is also the size that the size of fan-shaped aluminum steel 1 is greater than fan-shaped aluminium-clad steel wire 2.
In a preferred embodiment, in aluminum steel skin, the number of fan-shaped aluminum steel 1 is greater than the number of fan-shaped aluminium-clad steel wire 2 in aluminum steel internal layer, also be outer field fan-shaped aluminum steel 1 not corresponding one by one with the fan-shaped aluminium-clad steel wire of internal layer 2, but existence one to one and many-to-one situation.
The Novel composite cable that the utility model embodiment provides, by being twisted into aluminum steel skin with fan-shaped aluminum steel, and be twisted into aluminum steel internal layer with fan-shaped aluminium-clad steel wire, and make this Novel composite cable have that ampacity is large, the feature of anti-ice-snow function admirable, therefore can in following electrical network, widely apply.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
