Abstract
The utility model relates to a novel 330KV high tension cable line, it includes a plurality of cable cores, mica lacing, filling layer, polyvinyl chloride insulating layer, waterproof layer and restrictive coating, wherein, the mica lacing sets up respectively on each cable core, the filling layer cladding a plurality of cable cores, it is with polyvinyl chloride insulating layer, waterproof layer and restrictive coating ab intra in proper order and outer the setting, in be equipped with two heating steel wires in the restrictive coating. The utility model discloses a novel 330KV high tension cable line has the sound construction, be difficult for appearing the corona and can automatic ice -melt etc. A great deal of advantage.
Description
[technical field]
The utility model relates to a kind of cable, is specifically related to a kind of novel 330KV high-voltage cable, belongs to technical field of electric wires and cables.
[background technology]
The electric wire of prior art, when conveying high-pressure electricity, because electric field strength is large, makes the insulating properties of electric wire greatly reduce.Current practices well is the thickness increasing insulating barrier, the weight of electric wire will be made like this to increase, be unfavorable for that high-altitude is set up.
Meanwhile, the high-tension cable of prior art is erected at field usually, easily freezes in winter, easily forgets about it power transmission tower.
Therefore, for solving the problems of the technologies described above, the necessary one that provides has structure improved novel 330KV high-voltage cable, to overcome described defect of the prior art.
[utility model content]
For solving the problem, the purpose of this utility model is to provide a kind of sound construction, not easily occurs corona and can the novel 330KV high-voltage cable of automatic defrosting.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of novel 330KV high-voltage cable, and it comprises some cable cores, mica belt, packed layer, polyvinyl chloride insulation layer, watertight composition and restrictive coating; Wherein, described mica belt is arranged on each cable core respectively; The coated described some cable cores of described packed layer, itself and polyvinyl chloride insulation layer, watertight composition and restrictive coating successively from-inner-to-outer are arranged; Two Heating Steel Wires are provided with in described restrictive coating.
Novel 330KV high-voltage cable of the present utility model is set to further: described cable core is specially 3, and these 3 cable cores are isosceles triangle arrangement.
Novel 330KV high-voltage cable of the present utility model is also set to: described packed layer is silicon rubber filling layer.
Compared with prior art, the utility model has following beneficial effect: novel 330KV high-voltage cable of the present utility model has sound construction, not easily occurs corona and can the plurality of advantages such as automatic defrosting.
[accompanying drawing explanation]
Fig. 1 is the sectional drawing of novel 330KV high-voltage cable of the present utility model.
[embodiment]
Refer to shown in Figure of description 1, the utility model is a kind of novel 330KV high-voltage cable, and it is made up of a few parts such as some cable cores 1, mica belt 2, packed layer 3, polyvinyl chloride insulation layer 4, watertight composition 5 and restrictive coatings 6.
Wherein, described cable core 1 is copper core, and its concrete number is 3, the arrangement in isosceles triangle of these 3 cable cores 1.
Described mica belt 2 is arranged on each cable core 1 respectively, and this mica belt 2 can be fitted cable core 1 and packed layer 3, thus effectively can avoid the generation of corona phenomenon, extends the useful life of cable.
The coated described some cable cores 1 of described packed layer 3, itself and polyvinyl chloride insulation layer 4, watertight composition 5 and restrictive coating 6 successively from-inner-to-outer are arranged.This packed layer 3 is silicon rubber filling layer 3.By arranging described silicon rubber filling layer 3 and polyvinyl chloride insulation layer 4, thus make the insulating properties of this cable better.Described watertight composition 5 makes the water resistance of this cable good, is more suitable for field and uses.
Two Heating Steel Wires 7 are provided with in described restrictive coating 6, this Heating Steel Wire 7 can not only increase the structural strength of cable, so that large span is set up and is not broken, simultaneously, this Heating Steel Wire 7 can be energized and to heat restrictive coating 6, when on winter cable during icing, in time ice cube can be melted, and then avoid cable break or forget about it power transmission tower.
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection range that all should be included in this creation.
Claims (3)
