China's power industry has in recent years had the progress of advancing by leaps and bounds.Due to the fast development that domestic electrical is built, Present Domestic line corridor resource is increasingly in short supply, and especially the southeastern coastal areas such as Pearl River Delta, Yangtze River Delta Area have been difficult to find new corridor, and line corridor resource is precious.Therefore, how to improve the transfer efficiency of newly-built circuit, reduce line loss, no matter be for the active response of building a resource-conserving society, or for the actual demand of the problem in building power circuit, all significant.Meanwhile, China is vast in territory, circumstance complication, and in the area of these length and breadth of land, overhead construction is faced with again the impact of the adverse circumstances such as ice and snow, environmental corrosion, improve aerial condutor safety in operation and useful life problem also very urgent.

For improving the transfer efficiency of circuit, strengthening the fail safe that circuit runs, in ice and snow district of China, the wide geographic area such as coastal and island, in newly-built circuit, using the wire that electric energy loss is low, adaptive capacity to environment is strong necessary.In existing patent, the disclosed a kind of super corrosion-resistant type conducting wire of utility model patent CN201120096363.1, conductor forms by common aluminum steel is stranded, and this product only has anti-corrosion capability, and do not promote reducing the wastage, therefore application surface is narrower.

Utility model content

The purpose of this utility model be overcome traditional round line twist with one heart steel reinforced aluminium conductor line loss high, gather the problems such as ice and snow, corrosion resistance be poor, a kind of environmental friendliness energy-saving overhead wire used for intelligent electric network is provided.

Realizing the technical solution of the utility model is a kind of environmental friendliness energy-saving overhead wire used for intelligent electric network, comprises the steel core, strengthening core, conductive layer and the hydrophobic film that set gradually from the inside to the outside; Described steel core forms by galvanized steel wire is stranded; Described strengthening core is stranded in the outside of steel core, and strengthening core is steel wire and aluminum steel from the inside to the outside; Described conductive layer is stranded in the outside of strengthening core, comprises the conduction single line of at least two-layer concentric stranding, at least comprises one deck ladder track and be arranged at the Z-shaped line of outer field one deck in single line; Described hydrophobic film covers the outside of conductive layer, is fluorine-contaninig polyacrylate.

Described steel core adopts two-layer stranded, and inside arranges a steel core, outside even stranded six roots of sensation steel core.

Described strengthening core adopt 12 stranded; The diameter of every root strengthening core and the equal diameters of every root steel core.

Described conductive layer is two-layer stranded single line, is followed successively by ladder track and Z-shaped line; Described ladder track be 10 stranded; Described Z-shaped line be 16 stranded; The equivalent diameter of described ladder track and Z-shaped line is equal.

Have employed technique scheme, the utility model has following beneficial effect:

(1) strengthening core of the present utility model is aluminium-clad steel wire twisted wire, and conductor material is high-conductivity hard aluminum line, and wire alternating current-direct current resistance obviously reduces, and can reduce line loss more than 5%, remarkable in economical benefits.

(2) conductive layer of the present utility model is trapezoidal and outer " Z " type of internal layer, and conductor structure is tight, surface hydrophobic, is not easy to gather ice and snow, improves the Disaster Defense Capability of wire in ice and snow situation, and safety in operation improves.

(3) strengthening core of the present utility model contacts with the direct homogeneity of conductive layer, without electrochemical corrosion in corrosive medium, the stranded generation labyrinth slits of outer " Z " molded line simultaneously, corrosive medium is difficult to enter, thus wire corrosion tendency goes to zero, for the stronger region of corrosivity, circuit security of operation, the life-span is long.
