Description
Technical field
The utility model relates to aerial cable technical field, and particularly one adopts aluminum stranded wire of aluminum alloy core conductor, adopts the novel energy-conserving aerial cable of trapezoidal lay configuration.
Background technology
Current aerial insulated cable, conductor is based on aluminium stranded conductor, steel reinforced aluminium conductor, and aluminum stranded wire of aluminum alloy core conductor structure is less, adopts trapezoidal structure of pressing, and is applied to aerial insulated cable and still belongs to the development phase.The conductor structure of this aerial cable has following advantage compared with common steel reinforced aluminium conductor: the conductance of this wire aluminium alloy is 52.5%IACS, the conductance of aluminium is 61%IACS, aluminium alloy wire is more a lot of than the good conductivity of steel core, therefore compared with the steel reinforced aluminium conductor of same external diameter, there is D.C. resistance little; This aluminium alloy used for wire core instead of steel strand wire, and do not have steel strand wire, therefore there is not eddy current and magnetic hysteresis loss, therefore this wire alternating current-direct current resistance is smaller, so compare with common steel reinforced aluminium conductor conductor structure, have the advantage that transmission capacity is large; Due to the single material that aluminum stranded wire of aluminum alloy core is aluminum substrate, there will not be bimetallic electrochemical corrosion, so its anti-corrosion function is better than steel reinforced aluminium conductor conductor; Because aluminium alloy temperature-resistance characteristic is good, overload in short-term can be born, lightweight, shaft tower span can be strengthened, reduce shaft tower consumption.Therefore this wire has the object of energy-conservation, consumption reduction, environmental protection, has obvious economic benefit and social benefit, is of great importance to construction " resource-conserving, environmentally friendly " electrical network.
The overhead transmission line that development and application conductance is high, intensity is large, lightweight, sag is little and cost performance is excellent is the target that various countries electric power scientific worker pursues all the time.Thus, be not difficult to find out, the overhead cable of this project has energy-saving and environmental protection, reduces costs, increases transmission line capability, improves the aspect combination properties such as electric power netting safe running, after industrialization, in the near future, will widely apply in transmission line.This type of wire has great economic benefit and social benefit.
Utility model content
The purpose of this utility model is to provide a kind of aluminium alloy core and replaces traditional steel core, thus can weight reduction energy-saving and environmental protection, reduce the built on stilts insulated cable of line cost.
The invention discloses a kind of novel energy-conserving aerial insulated cable, comprise the conductor at center, extrude conductor shield outward successively and thickness is the insulating barrier of 2.5 ~ 3.4mm or directly extrudes the insulating barrier that thickness is 2.5 ~ 3.4mm at conductor; Described conductor is made up of aluminium alloy core and the single or multiple lift aluminium stranded conductor be extruded in outside aluminium alloy core.
In the utility model, preferably, the circular aluminum alloy filaments that described aluminium alloy core is 295 ~ 350MPa by many intensity adopts that the structure of 1+6 is stranded to be formed.
In the utility model, preferably, when described aluminium stranded conductor is multilayer, every layer of trapezoidal aluminium monofilament all adopting many cross sections identical presses stranded 360 degree of structures, and the height of the trapezoidal aluminium monofilament that the outer aluminium stranded conductor of aspect ratio of the trapezoidal aluminium monofilament that the trapezoidal aluminium monofilament radian that the outer aluminium stranded conductor of its trapezoidal aluminium monofilament camber ratio adopted between layers adopts is little and adopted between layers adopts is high.
After adopting technique scheme, this utility model has following beneficial effect:
(1) conductor adopts aluminum stranded wire of aluminum alloy core, and compared with steel reinforced aluminium conductor, can reduce the loss of circuit, same conductor external diameter is compared, and this invention conductor loading electric current is large;
(2) conductor three layers adopts aluminium alloy core and aluminium stranded conductor, and conductor is the structure composition that single material is formed, and there will not be bimetallic electrochemical corrosion, so good corrosion resistance;
(3) aluminium alloy core of conductor employing is lighter by 65% than the steel core with cross section; Higher than the aluminium stranded conductor intensity with cross section, draw anharmonic ratio large; The tower bar number 10 ~ 20% laid can be reduced;
(4) aluminium stranded conductor in conductor adopts and trapezoidally presses structure, and to press coefficient high with circle single line ratio, and same uiform section, can reduce diameter 9 ~ 14%, with conductor diameter size, and can increasing section utilance 18 ~ 23%;
(5) insulating barrier that adopts adopts has weather-proof, uvioresistant, cold-resistant material, can retarding ageing, increases useful life, is used in environment and dislikes cold district slightly.
