Abstract
The utility model discloses a steel-cored shaped aluminum alloy stranded wire, which comprises a steel core consisting of steel wires and an aluminum conductor wrapped around the steel core. The aluminum alloy conductor comprises multiple layers of aluminum alloy wires which are in linear structures, and each two adjacent aluminum alloy wires are closely wrapped outside the steel core. As tensile strength and structure deformation resistance of current carriers are increased and the conventional round cable structure is changed into a linear structure, the steel-cored shaped aluminum alloy stranded wire can be used as an overhead special conductor with advantages of smooth and compact surface, freezing resistance, wind resistance, corrosion prevention and the like on the basis that the tensile strength of the conductor is increased.
Description
Technical field
The utility model relates to a kind of in big leap, and the novel conductive wire that rugged environments such as heavy icing area use is specifically related to a kind of steel core moulding aluminium alloy stranded conductor.
Background technology
The big river of China is cross-regional, the safe operation of the transmission line of the city net of mountain area, heavy icing area, highlands and rural power grids is had a strong impact on, strong wind, sleet, icing easily cause lead to deice faults such as jump, phase fault, lead collision lightning conducter, cause the loss of power accident of wire breaking and tower falling when serious easily.The electrical network predicament that driving snow, sleet, icing cause, and the railway that mains breakdown causes is paralysed these equal serious threat people property safeties.Design a lot of ways and address this problem people, improve the lead intensity, also develop various anti-ice and snow leads, as difficult accumulated snow lead, the difficult accumulated snow lead of band wing, self damping conductor etc. except adopting the high-strength aluminum alloy lead.Not only the manufacturing process component difficulty is big for these several leads, adverse factors such as the increase of lead cost is big, cost an arm and a leg, the increase of lead unit mass, the increase of lead sag, construction technique complexity.
The utility model content
The utility model purpose: the utility model is in order to solve the deficiencies in the prior art, provide that a kind of manufacturing process is simple, cost increase less, have anti-ly wave, the steel core moulding aluminium alloy stranded conductor of anti-ice-snow.
Technical scheme: a kind of steel core moulding aluminium alloy stranded conductor, comprise steel core of forming by steel wire and the aluminium conductor that wraps in the steel core periphery, described aluminium conductor comprises the multilayer aluminium alloy wire, described aluminium conductor adopts the aluminium alloy wire of molded lines structure, and adjacent two aluminium alloy wires closely cooperate and are wrapped in described steel core periphery.
As further improvement of the utility model, described steel core adopts the stranded heart yearn that forms of extra high strength steel wire, improves the tensile strength and the icing overload capacity of lead, and described extra high strength steel wire tensile strength is greater than 1400MPa.
As further improvement of the utility model; described aluminium conductor adopts the high-strength aluminum alloy line; the aluminium alloy wire lead has good tensile strength; described high-strength aluminum alloy line tensile strength is greater than 295MPa; conductance is greater than 53%IACS; maximum operation (service) temperature is 90 ℃; increase more than 30% than tensile strength with cross section ordinary steel core aluminum stranded wire; therefore when novel steel core moulding aluminium alloy stranded conductor runs into strong wind, sleet and icing; the good resistance load capacity is arranged, can protect transmission line to avoid the influence of strong wind, sleet, ice and snow to greatest extent.Aluminium conductor adopts heat-resisting high-strength aluminium alloy wire, makes lead possess the high temperature difference characteristic, can prevent that the low-temperature condition lower wire from freezing, and can improve the lead working temperature and melt the ice and snow that covers by improving the ampacity of transmission line again.
The form of described aluminium alloy wire is not limit, and its single line molded lines structure can also can be Z molded lines, S molded lines for the fan molded lines, and what traditional lead adopted is circle line structure form, and contacting between single line and the single line is the line contact.The utility model adopts molded lines version, and contacting between single line and the single line is the face contact, because contacting of face and face improved and pressed coefficient, makes twisted wire stranded tightr, and more rounding is smooth on the surface reaches bigger moment of torsion, has reduced the possibility of icing; Conductive line surfaces is smooth, and the self-damping characteristic is more excellent, has reduced the lead vertical vibration and has turned round shake.Under same cross-sectional; the utility model steel core moulding aluminium alloy stranded conductor external diameter is littler than plain conductor; therefore the thick relative plain conductor of anti-ice cover is little; the blast of the utility model lead, ice load are littler than plain conductor to a certain extent; add that it has bigger load overload capacity than plain conductor; the guardwire of energy limit is avoided the collapse accident that breaks to a certain extent.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model steel core moulding aluminium alloy stranded conductor had both had functions such as antivibration, anti-ice-snow, have advantages such as vibrationproof, tensile strength are big again, thereby reduce the iron tower cost of investment, economize the land resource; Novel steel core moulding aluminium alloy stranded conductor has smooth surface, compact conformation, not-easy-to-freeze and can reduce the frequency of waving of lead, excellent self-damping characteristic is arranged, be that present reaching is suitable for one of aerial condutor of China's power grid construction most in the future, be specially adapted to heavy icing area, big leap, consecutive low temperature sleet, the use of area, high mountain air port.
