The structure of the utility model is characterized in that the reinforced core is positioned in the central part, a plurality of supporting components is wrapped on the reinforced core to form one or three supporting stranded layers, a plurality of shaped conductors is tightly stranded outside the supporting stranded layers to form outer stranded layer; the supporting components in the same supporting stranded layer have the same shape, the cross section of the supporting component is circular, convex, concave, cross-shaped or tile-shaped; the shaped conductor is trapezoidal, Z-shaped or S-shaped. The utility model has easily-realized production process and low cost and can be well applied in the high-voltage transmission and transformation line project; the conductor has smooth surface, small aerodynamic drag coefficient and stable structure; the conductor used in the transmission and transformation line project can help reduce corona loss and save operating cost; the conductor produces little operating noise, suitable for being used in residential areas; phenomena of strand folding and standing out are almost avoided, thereby the conductor is adaptive to batch production and spread placement.
Description
Technical field
The utility model relates to a kind of molded lines expanded conductor, especially a kind of electric power transfer lead that is used for the high voltage power transmission and transforming line project.
Background technology
Expanded conductor is to enlarge wire diameter under the condition that needn't increase metal material, makes lead when high voltage power transmission, plays the corona loss that reduces under the circuit high pressure field intensity, improves electric energy transmitting efficient.The expanded conductor of existing manufacturer production all is that stranded steel core (also single steel wire) is adopted at the center, and internal layer circle aluminum steel adopts to dredge and moves into capable hole enlargement, and skin adopts circular aluminum steel to carry out closely stranded.Chinese patent 02261404.4 discloses the expanded conductor that the metallic support pipe is adopted at a kind of lead center, by lead being made the bigger hollow tube of diameter, reaches the expansion wire diameter.200320114093.8 of Chinese patents adopt to be dredged around the hole enlargement mode, by dredging around some hole enlargement layers at steel core and outer stranded aluminium conductor interlayer, reaches hole enlargement.Chinese patent 200620078087.5 adopts the resin-based long fibre composite core of side face profile of tooth to make strengthening core, adds some thin stranded around aluminum steel.Chinese patent 200820186319.8 is to twine the hollow aluminum conductor outside central reinforce member, and what rely on aluminium conductor itself hollowly comes hole enlargement.Though these expanded conductors by metal hollow tube, aluminum steel dredge around, the composite core skeleton supports and the hollow aluminum conductor comes hole enlargement, has reached the electric field strength that reduces conductive line surfaces, has reduced the generation of corona, has reduced radio interference level, has reduced cost.But because the outer circle aluminum steel that adopts is closely stranded, conductive line surfaces has also increased the generation of corona with regard to irregular circle.Also have traditional expanded conductor to adopt and take out a burst mode, unsettled structure causes lead to occur phenomenons such as " folded silk ", " sudden and violent strand " easily in work progress, influences construction schedule.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of smooth surface, Stability Analysis of Structures is provided, can reduces corona loss, improves the molded lines expanded conductor of circuit through-put power.
The technical scheme that provides according to the utility model, described molded lines expanded conductor, comprise strengthening core, supporting member and molded lines, it is characterized in that: the center of molded lines expanded conductor is a strengthening core, outside strengthening core, twine some supporting members and form 1～3 layer and support the strand layer, form outer twist layer supporting the outer closely stranded some molded lines of strand layer.
Described support strand layer is identical with the supporting member shape of one deck.
The cross sectional shape of described supporting member is circle, " protruding " shape, " recessed " shape, "+" shape or watt shape.Described molded lines is trapezoidal, " Z " shape or serpentine.
The beneficial effects of the utility model are, production technology realizes easily, cost is lower, connect gold utensil and construction technology identical with conventional wires, can apply in the high voltage power transmission and transforming line project preferably; This kind conductive line surfaces is smooth, air resistance coefficient is little, Stability Analysis of Structures, and this lead of power transmission and transformation line engineering application can reduce corona loss, save operating cost; The operation noise little, suitable people live; Be not prone to phenomenons such as " folded silk ", " sudden and violent strand ", suitable batch production and exhibition are put.
