Abstract
The invention relates to the field of power transmission, in particular to a single-core anti-snow damage cable. The cross section of the single-core anti-snow damage cable takes the shape of an equilateral triangle. The cable comprises a main conductor, a mica fire-retardant layer, an insulating protecting layer, water-blocking paste, a water-blocking tape and an outer sheath from inside to outside in sequence, wherein the main conductor consists of a plurality of twisted copper lines. Compared with the prior art, the single-core anti-snow damage cable has the advantages that firstly, due to the anti-snow damage design, that is, the cross section of the cable takes the shape of the equilateral triangle, the area of the power transmission line is small in any angle facing to the sky, and a relatively small side or a smallest side of the whole power transmission line is always kept facing to the sky even when the power transmission line is affected by wind or other factors; secondly, due to the water-blocking design, that is, the structure of the water-blocking paste and the water-blocking tape is added, the water-blocking and current leakage prevention properties of the cable are greatly improved under the situation of serious accumulated snow.
Description
Technical field
The present invention relates to electrical distribution field, specifically, is the anti-crushing by snow cable of single core.
Background technology
Existing power main is when carrying out electric power conveying at a distance, major part needs high-tension electricity bridge height pipeline, general adjacent high-tension pole spacing is 200 meters, because the deadweight of spacing large power transmission line is also large, stretchingly can not tighten power transmission line, after being subject to wind-force or the impact of other factors, pipeline can not keep the minimal face of sliver towards sky always, be very easy to accumulated snow, accumulated snow again after accumulated snow freezes, so repeatedly, power main pliability and tensile strength reduce simultaneously, the waterproof ability of oversheath is deteriorated, cause power main eventually break or leak electricity, have a strong impact on electric power conveying.Therefore a kind of single core anti-crushing by snow cable tool is provided to be of great significance.
Summary of the invention
The object of the present invention is to provide the power main of a kind of anti-crushing by snow, waterproof,
Goal of the invention of the present invention is achieved through the following channels: the anti-crushing by snow cable of a kind of single core; the cross section of described cable is equilateral triangle; cable is followed successively by leading body, mica flame retardant coating, insulating protective layer, waterproof paste, waterstop and oversheath from inside to outside, and to be that strand copper wire is stranded form described leading body.
As the further optimization of this programme, described insulating protective layer is LSOH anti-flaming polyethylene insulation protective layer.
Compared with the prior art, advantage of the present invention is: one is anti-crushing by snow design, power main cross section is equilateral triangle, this design makes all very little towards terrace of which angle of power main, even if after being subject to wind-force or the impact of other factors, pipeline all can keep less of sliver or minimal face towards sky always.Two is waterproofing design, by increasing waterproof paste, waterstop structure, substantially increases the waterproof of cable under accumulated snow serious conditions, anti-creeping ability.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Embodiment
As shown in Figure 1; the anti-crushing by snow cable of single core provided by the invention; the cross section of described cable is equilateral triangle; cable is followed successively by leading body 3, mica flame retardant coating 2, insulating protective layer 1, waterproof paste 6, waterstop 7 and oversheath 8 from inside to outside, and described leading body 3 forms for strand copper wire is stranded.
Described insulating protective layer 1 is LSOH anti-flaming polyethylene insulation protective layer.
Claims (2)
1. the anti-crushing by snow cable of single core; it is characterized in that; the cross section of described cable is equilateral triangle; cable is followed successively by leading body (3), mica flame retardant coating (2), insulating protective layer (1), waterproof paste (6), waterstop (7) and oversheath (8) from inside to outside, and described leading body (3) forms for strand copper wire is stranded.
2. the anti-crushing by snow cable of single core as claimed in claim 1, is characterized in that, described insulating protective layer (1) is LSOH anti-flaming polyethylene insulation protective layer.
