Description
Technical field
The utility model belongs to aerial cable technical field, especially relates to a kind of aerial insulated cable of parallel set beamforming.
Background technology
China's rural area Low-voltage Transmission system is the overhead wire adopting bare exposed conductor at first more, self-evident, this mode fail safe extreme difference.Therefore tentatively adopt twisting type bundled insulated conductors afterwards, although considerably increase fail safe, because wire is stranded, lead inductance is comparatively large, and between line, dielectric constant is little, and therefore capacitance is little, and circuit reactance is high, and line loss is high.At present, parallel bunched overhead insulated cable is the product applied in State Power Corporation's Rural Power Grid Construction " 15 " program for the development of science and technology, this cable conductor becomes boundling shape to combine, anti-pull-off force comparatively single line is multiplied, single-phase wire break accident reduces, operating safety factor improves, anti-lightning strike, anti-electricity-theft, anticreep successful is improved, and when mounting and installation, only need some special-purpose assorted instruments, do not need cross-arm and porcelain piece, a large amount of gold utensils can be reduced, compared with common aerial insulated cable, there is fairly obvious advantage.But existing parallel bundling aerial insulated cable exists the not high fault of construction of insulation property, and when the tipping of three-phase and four-line formula easily by the order wrong of phase line, cause danger.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of inductance reduced between cable core, strengthen the dielectric constant between phase line, increase capacitance, reduce circuit reactance significantly, improve insulation property and there is the aerial insulated cable of the parallel set beamforming of prompting phase line tipping order function.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of aerial insulated cable of parallel set beamforming, comprise multi-cable core and the insulation dowel for being connected to each other by each single described cable core, described cable core comprises electric conductor and is coated on the insulating barrier outside described electric conductor, the anti-of graphite that speckle with being provided with one deck braiding between described electric conductor and described insulating barrier tears line layer, with the integrated described insulation dowel of the outer surface of described insulating barrier, single described cable core is connected into square, one in star-like or flat pattern, the outer surface of described insulating barrier is provided with the breach for distinguishing different phase sequence.
Further, described electric conductor is wound in by multiply thin copper wire is stranded the copper electric conductor that cross section is circle.
Further, described insulating barrier is by a kind of shielding layer structure carrying out extruding in weather-proof polyvinyl chloride, weather-resistance polyethylene or crosslinked polyethylene.
The advantage that the utility model has and good effect are: adopt technique scheme, compared with existing aerial cable, the utility model has the following advantages: 1, adopt three-phase and four-line to power, make distribution transforming three-phase load unbalance degree be down to minimum, reduce neutral current, effectively reduce inductance between resistance loss and cable core, strengthen dielectric constant, add capacitance, circuit reactance is significantly reduced, finally realize the object that damage falls in dilatation; Single cable core is connected into the one in square, star-like or flat pattern by the dowel that 2, insulate, and tension resists disconnected ability to be multiplied, and reduces single-phase wire break accident, decreases shaft tower, cross-arm and porcelain piece, save a large amount of metal during installation; 3, the insulating barrier of coated with conductive conductor is undertaken extruding forming by the one in weather-proof polyvinyl chloride, weather-resistance polyethylene or crosslinked polyethylene, greatly improve the insulation property of itself, insulating can reduce shaft tower height, not by trees, the impact of the complex environments such as groups of building, can lay along wall and thoroughly save electric pole, project cost is low; 4, be arranged on the breach of the outer surface of insulating barrier for distinguishing different phase sequence, during tipping can not wrong order, cause danger.
