Abstract
The utility model provides an aerial insulated cable, which comprises at least two insulated wire bundles, wherein each insulated wire bundle comprises a conductor and an insulating layer which coats the periphery of the conductor; and the insulating layer employs weather-resistant polyvinyl chloride insulation or weather-resistant cross-linked polyethylene insulation. By changing the combination shape of the insulated wire bundles of the aerial insulated cable, the inductance value of wires is decreased, and the loss of electric energy in a low-voltage distribution network is reduced; by adoption of a weather-resistant polyvinyl chloride insulation material or a weather-resistant cross-linked polyethylene insulation material, safety performance is improved, and weather resistance is high; and steel cores are arranged in the conductors, so the tensile strength of the cable is improved, a large-span aerial cable can be laid, and the aerial insulated cable is applicable to towns, green belts and mountainous areas, simple in manufacturing process and low in cost.
Description
Technical field
The utility model relates to electrical equipment technical field, particularly a kind of aerial insulated cable.
Background technology
At present, generally adopt the three-phase four-wire system mode to supply power in the low-voltage network, lead is that common aerial insulated wire is set up in single phase-splitting, and required line materials was more when this aerial insulated wire set up, and electric energy loss is bigger, is unfavorable for environmental protection and construction.
The utility model content
The purpose of the utility model is to propose the lower aerial insulated cable of electric energy loss in a kind of low-voltage network.
For achieving the above object; The utility model provides a kind of aerial insulated cable; Comprise at least two bundled insulated conductorses, said bundled insulated conductors comprises conductor and is coated on the insulating barrier of conductor circumference that said insulating barrier employing weatherability polyvinyl chloride insulation or weatherability are crosslinked polyetylene insulated.
Further, in above-mentioned aerial insulated cable, the insulating barrier of said at least two bundled insulated conductorses connects through dowel, and it can be twin-core type or star-like.
Further, in above-mentioned aerial insulated cable, be provided with steel core in the said conductor.
Further, in above-mentioned aerial insulated cable, said conductor is the aluminum or aluminum alloy conductor.
The utility model aerial insulated cable has reduced the inductance value of lead through changing the bundled insulated conductors combined shaped of aerial insulated cable, has reduced electric energy loss in the low-voltage network; Adopt weatherability polyvinyl chloride insulation or the crosslinked polyetylene insulated insulating material of weatherability again, improved security performance, good weatherability; Owing to because of steel core is arranged in the conductor, improved the tensile strength of cable, can be used to lay the aerial cable of large span at last, be adapted at cities and towns, greenbelt, mountain area use, and manufacturing process be simple, cost is relatively low.
