Abstract
The utility model relates to a wire cable and specifically relates to an aluminum alloy wire with extra heavy steel cores. The aluminum alloy wire comprises seven extra heavy steel cores disposed at a central position, and at least two middle-intensity aluminum alloy wire layers wrapped around the seven extra heavy steel cores. The cross section of the extra heavy steel core is circular and the extra heavy steel core comprises an extra heavy steel core line and a galvanizing layer wrapped around the outer surface of the extra heavy steel core line. The aluminum alloy wire with extra heavy steel cores has following advantages that 1 the aluminum alloy wire has good heat resistant performance and long-time operating temperature of 210 degree centigrade which is three times that of a steel-core aluminum conductor, that 2 the extra heavy steel cores has characteristics of low expansion coefficient, low loosening degree, large tensile strength, and long service lives, that 3 the aluminum alloy wire has transmission carrying capacity two times that of the steel-core aluminum conductor, low line loss, high conductivity ( the conductivity is more than or equal to 60 percent of IACS), and saved electric energy, and that 4 a line with same capacity has low investment cost.
Description
Technical field
The utility model relates to a kind of leader cable, specifically, relates to a kind of extra-heavy aluminium alloy conductors steel.
Background technology
The carrier that overhead power transmission conducting wire is carried as electric power occupies very consequence in transmission line.In the prior art, the overhead power transmission conducting wire of extensive use is steel reinforced aluminium conductor, and it has following defective: 1, heat resistance is poor, and heat resisting temperature is low, only is about 70 ℃; 2, tensile strength is low, and useful life is short; 3, the transmission ampacity is little, line loss big, operation troubles rate height; 4, cost of investment height.
The utility model content
The purpose of this utility model is, provides a kind of extra-heavy aluminium alloy conductors steel, to solve the problems of the technologies described above.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of extra-heavy aluminium alloy conductors steel is characterized in that: comprise the strong steel core of seven Gents that is arranged on the center and the two-layer at least middle strength aluminium alloy lead that is wrapped in the strong steel core of described seven Gents outside; The cross section of described extra-heavy steel core is rounded, comprises extra-heavy steel core wire and the zinc coat that is located at extra-heavy steel core wire appearance.
Beneficial effect: compare with the steel reinforced aluminium conductor of routine, the utlity model has following advantage: 1, heat resistance is good, and 210 ℃ of long-term work temperature are 3 times of steel reinforced aluminium conductor long-term work temperature; 2, the coefficient of expansion of extra-heavy steel core is little, and degree of speeding is little, and tensile strength is big, long service life; 3, the transmission ampacity can reach 2 times of steel reinforced aluminium conductor, and line loss is little, and the conductance height (conductance 〉=60%IACS), saves energy; 4, the circuit of same capacity, cost of investment is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
