Abstract
The utility model discloses a super heat-resistant high-strength steel-reinforced aluminium alloy conductor comprising a zinc-coated invar steel wire (1) and a super heat-resisting aluminium alloy wire (2), wherein the zinc-coated invar steel wire (1) is used as a core wrapped by the super heat-resisting aluminium alloy wire (2) so as to form an integral steel-reinforced aluminium alloy conductor. The long-term working temperature of the super heat-resistant high-strength steel-reinforced aluminium alloy conductor is 210 DEG C and is three times that of an ordinary aluminium wire, the electric conductivity is higher than or equal to 60 percent IACS (International Annealed Copper standard), and the current-carrying capacity is two times that of an ordinary ACSR (Aluminum Cable Steel Reinforced), thereby increasing the utilization rate of aluminum and saving the construction cost.
Description
Technical field
The utility model is a kind of super heat-resistance high-strength degree aluminium alloy conductors steel, belongs to the overhead power transmission conducting wire field.
Background technology
Along with the quick growth of Electricity Demand, the requirement of electric power energy in transmission is also more and more higher.China is the country of many rivers and lakes, many high mountain gorges, particularly Xi Bu exploitation, with the water power in the water power of northwest, thermoelectricity, southwest be sent to comparatively flourishing in, the eastern region, ultra-high-tension power transmission line certainly will be through various leap sections district, and the demand of the big capacity conductor wire of big leap of property is inevitable.Yet at present, in China's overhead transmission line employed lead basically still based on traditional steel reinforced aluminium conductor, its heat resistance, decay resistance relatively a little less than, so the transmission line capability of circuit, useful life are subjected to certain restriction.
Aluminium alloy conductor is compared with steel reinforced aluminium conductor, and its incomparable advantage is arranged, in big capacity, long distance, big leap, EHV transmission, and absolute advantage; In rural power grids, urban network restructuring, be not only advanced but also economic good product, it is the renewal product of ordinary steel core aluminum stranded wire, also is the product of energy-conservation, material-saving, save land (saving the transmission of electricity corridor).The fifties begins to adopt so far in the world, states such as West Europe, Northern Europe, the U.S., Canada, Japan extensively adopt, the transmission line of France almost uses aluminium alloy conductor more than 90%, also to reach more than 50%, the use amount of Southeast Asian countries is being increased sharply year by year in Japan.
Summary of the invention
The purpose of this utility model is: a kind of super heat-resistance high-strength degree aluminium alloy conductors steel is provided, improves the resistivity of lead, this lead is applicable to high strength, big capacity, crosses over transmission line greatly, can improve transmission capacity and line security significantly.
Technical solution of the present utility model is: this lead comprises zinc-plated invar silk and superalloy line, adopts zinc-plated invar silk as core, and core coats superalloy line all-in-one-piece aluminium alloy conductors steel outward.
The utlity model has following advantage: 1, aluminium alloy conductors steel long-term work temperature is 210 ℃, be 3 times of conventional aluminium line length phase working temperature, conductance 〉=60%IACS, ampacity are 2 times of ordinary steel core aluminum stranded wire, improve the utilance of aluminium, saved construction cost; 2, the steel wire of lead adopts zinc-plated invar silk, and its coefficient of expansion is little, and sag reduces; 3, use this lead can reduce floor space, alleviated the problem of the nervous headroom deficiency in circuit corridor.
