Description
Technical field
The utility model relates to a kind of electric wire, and especially a kind of bunched aerial insulated cable, belongs to technical field of power transmission equipment.
Background technology
For in the overhead transmission line of rated voltage 1kV, existing aerial insulated cable wire harness easily obscures winding, cause the problem of three-phase equilibrium, be not easy to mounting and installation, not only wasting space, also need extra installation accessories, cost maintenance cost is installed higher, line loss is higher, in addition, the useful life of cable is lower, existing cable insulate in hot environment and heat dispersion poor, fire resistance is poor, bad mechanical property, shielding is poor, signal attenuation degree is high, normal power-up in hot environment can not be ensured, transmit various control signal, alarm signal, when a fire, also can discharge the dense smoke hindering vision and the toxic gas causing people to suffocate, contaminated environment.
Utility model content
The purpose of this utility model is to propose a kind of bunched aerial insulated cable, bunched aerial insulated cable provided by the utility model not only has excellent insulation property and mechanical performance, anti-signal disturbing function, in hot environment, not there is combustibility, toxic gas can not be produced, contaminated environment, and be easy to mounting and installation, save space, decrease installation accessories consumption, solve three-phase equilibrium problem, reduce line loss more than at least 30%, can also manufacturing cost be saved, enhance productivity, extend the useful life of cable.
The purpose of this utility model is achieved by the following technical programs:
A kind of bunched aerial insulated cable, comprises four eradication marginal zones, correspondence is coated on the wire that often eradication marginal zone is middle and the dowel be connected between adjacent two insulating tapes; Described wire comprises leads core and insulating barrier, described core of leading adopts twisted wire, lead described in described insulating barrier is coated on outside core, insulating tape is provided with triangular bump partly or completely, described in be provided with the triangular bump number often thoroughly done away with on marginal zone of triangular bump different.
In addition, the utility model technique scheme is also improved as follows further:
Described twisted wire is incorgruous by wire adjacent layer, and stranded forming is pressed in the disposable layering of outermost layer left-hand, and described wire adopts more than one soft circular copper wire or firmly round aluminum steel.
Described insulating tape adopts flexible PVC or the crosslinked polyethylene of low-smoke bittern-free highly fire-proof.
Described insulating barrier adopts black weatherability polyvinyl chloride or wear well polythene or weatherability crosslinked polyethylene.
In order to strengthen the anti-pull-off force of cable, be provided with reinforcement in described dowel, described reinforcement forms by least one thin round steel wire is stranded.
The utility model has the following advantages:
1, the utility model has excellent insulation property and mechanical performance, when a fire, the dense smoke hindering vision and the toxic gas causing people to suffocate can not be discharged, not there is combustibility, the propagation of flame caused by electric wire can be suppressed, ensure normal power-up in fire, transmit various control signal, alarm signal.
2, toxic gas can not be produced when the utility model is discarded, contaminated environment.
3, the utility model has fine flexibility and hot strength, can strengthen the effect that external force resistance is broken.
4, the utility model have explosion-proof, corrosion resistance is strong, ampacity is large, radiation hardness, mechanical strength are high, volume is little, lightweight, life-span long, smokeless feature.
5, the utility model is easy to mounting and installation, saves space, decreases installation accessories consumption, solves three-phase equilibrium problem, reduces line loss more than at least 30%.
6, the utility model adopts disposable extruding, and saves the manufacturing cost of more than 1 times, the production efficiency on improving 1 times.
7, the utility model has the triangular hill phase-splitting mark very easily distinguished, and not easily obscures.
8, the utility model adopts weather resistant materials, can extend the useful life of cable.
