Abstract
The utility model discloses a wisdom energy is with low wind pressure low noise aerial [insulated] cable, from interior to exterior strengthen the resistant crosslinked polyethylene of the time insulating layer of core, soft aluminium molded lines stranded conductor, semiconduction internal shield layer and grey for the aluminum alloy in proper order, the resistant crosslinked polyethylene of the time insulating layer of grey includes that the circumference body is insulating and follows circumference body insulating surface, strengthens four archs that the core direction is extended to keeping away from the aluminum alloy, four protruding evenly distributed, two adjacent bellied cross -section line of centres's contained angle is 90. The utility model discloses a 4 individual protruding structure along circumference evenly distributed, when wind during through this cable, the arch can reduce the regional area of the backward flow of wind behind the cable, can reduce the vibration range and the frequency of cable under 45ms and the following wind speed condition to it makes an uproar effectively to reduce the wind resistance soft breeze of cable.
Description
Technical field
This utility model is related to a kind of low blast low noise aerial cable of wisdom energy.
Background technology
Aerial insulated cable is typically laid in street both sides and the intensive road roadside of house, under running into high wind conditions, general
Logical aerial insulated cable easily produces and vibrates with frequency by a relatively large margin, on the one hand easily causes the shaft tower life-span fall setting up cable
Low and collapse, another aspect vibration can cause noise, and the aerial cable using low blast low noise can reduce wind resistance and wind
Make an uproar, be conducive to improving aerial cable operating safety factor and reduce sound pollution.Conventional aluminium core aerial insulated cable pull-off force
Less, stringing span very little, many using shaft tower quantity, wind loading rating is poor, is unfavorable for economizing on resources and safety coefficient is low；Conventional
Steel-cored aluminum strand core overhead insulated cable, current-carrying capacity is little, and ability to transmit electricity is poor, and weight is big, and span is less, is unfavorable for economizing on resources；
Conventional aluminium alloy core aerial insulated cable, current-carrying capacity is little, and ability to transmit electricity is poor, is unfavorable for economizing on resources.

To being followed successively by outward, aluminium alloy strengthening core, soft aluminum molded line with stranded conductor, semiconductive internal shield and the weather-proof crosslinked polyethylene of Lycoperdon polymorphum Vitt are exhausted
Edge layer；The weather-proof crosslinked polyetylene insulated layer of described Lycoperdon polymorphum Vitt includes circumferential body insulation and circumferentially body insulating surface, to away from
Four projections that aluminium alloy strengthening core direction extends；Described four projections are uniformly distributed, and two neighboring raised kernel of section is even
The angle of line is 90 °.
Described four raised geomeries are identical.
Described four raised outer surfaces are cambered surface.
Described four raised peaks with the vertical dimension of circumferential body insulated outer surface with outside diameter of cable ratio are
0.09.
Aluminium alloy strengthening core stranded is formed according to the structure of 1+6 by 7 strands of strengthening cores.
Employ technique scheme, this utility model has following beneficial effect：(1) this utility model adopts 4
Circumferentially equally distributed bulge-structure, when wind passes through this cable, projection can reduce recirculation zone after cable for the wind
Area, it is possible to decrease the Oscillation Amplitude of cable and frequency under 45m/s and following wind friction velocity, thus effectively reduce the wind resistance of cable
Make an uproar with wind.
