Abstract
The utility model relates to a hard aluminum conductor with an energy-saving aluminum alloy core and especially relates to a harm aluminum conductor having an energy-saving aluminum alloy core and applied for long-distance wide-span and new power transmission line construction and old electrical network reconstruction. The harm aluminum conductor which belongs to the electric power transmission technical field comprises energy-saving hard aluminum wires and the energy-saving aluminum alloy core. The energy-saving aluminum alloy core is formed by an energy-saving aluminum alloy wire. The energy-saving hard aluminum wires which are a plurality of independent wires with the same size surround the outer side of the energy-saving aluminum alloy core. The energy-saving aluminum alloy core adopted as the core of the conductor is much lighter than a steel core and has great conducting capabilities. Compared with a common aluminum alloy core, the energy-saving aluminum alloy core which has conductivity up to 55% IACS has the conductivity increased by 2.5% IACS. Therefore, the hard aluminum conductor with the energy-saving aluminum alloy core has more prominent effects.
Description
Technical field
The utility model relates to a kind of energy-saving aluminium alloy core hard aluminum wire, particularly a kind of long distance, large span and new transmission line construction, and the energy-saving aluminium alloy core hard aluminum wire of old electric network reconstruction belongs to electric power transportation technology field.
Background technology
Develop rapidly along with national economy, China's power industry has had the progress of advancing by leaps and bounds, strategic plan according to " transferring electricity from the west to the east, north and south supplies mutually, national network ", at a distance, the construction of large capacity transmission circuit is imperative, also have higher requirement to overhead power transmission conducting wire simultaneously, as the decision-making that improves transmission line capability, mainly solve from two approach, the one, improve transmission voltage, the 2nd, improve transmission current, under the certain prerequisite of voltage, improve transmission current density, the transmission line capability that namely improves the wire unit are is very important with regard to what show.At present, the employed wire of China's overhead transmission line still is traditional steel reinforced aluminium conductor basically and since its heat resistance relatively a little less than, so the transmission line capability of circuit is subject to certain restrictions.
The effect of power construction in the national economic development is increasing, and the development of power industry is concerning overall people's exhibition of national economy.Along with this situation, a new step has been stepped up in the power construction of China, has also become the task of top priority and the research and development of pushing forward new technology and new product comprehensively substitute existing product.The aluminum stranded wire of aluminum alloy core line is less than same specification ordinary steel core aluminum stranded wire resistance, transmission line capability is large, lightweight, intensity is high, based on these advantages, the use amount increase year after year of aluminium alloy conductor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of energy-saving aluminium alloy core hard aluminum wire is provided, and is mainly used in long distance, large span and new transmission line construction, old electric network reconstruction.
The technical scheme that provides according to the utility model, energy-saving aluminium alloy core hard aluminum wire, comprise energy-conservation hard-drawn aluminium wire and energy-saving aluminium alloy core, the energy-saving aluminium alloy core is made of an energy-saving aluminium alloy line, energy-conservation hard-drawn aluminium wire is some single lines of the same size, and it is arranged in the energy-saving aluminium alloy core along the energy-saving aluminium alloy core diameter to circle-shaped encirclement outside.
Described energy-saving aluminium alloy core is made of to being circle-shaped some concentric strands that are arranged in the aluminium alloy wire periphery an energy-saving aluminium alloy line and energy-saving aluminium alloy wire diameter.
Described energy-conservation hard-drawn aluminium wire is one deck, four layers at the most at least, and the single line adjacent layer strand that forms energy-conservation hard-drawn aluminium wire is on the contrary, and outermost layer twists to being dextrad.
The utlity model has following advantage: the utility model has used the energy-saving aluminium alloy core as the wire core, aluminium alloy core is compared light many of steel core, possesses again good conductive capability, and the energy-saving aluminium alloy core is compared the common aluminum alloy core, conductance reaches 55%IACS, improved 2.5%IACS, more remarkable effect.The peripheral multi-layer energy-saving hard-drawn aluminium wire conductance that coats is 63%IACS, compares common aluminum steel and improves 2%IACS.The energy-saving effect of overall energy-saving aluminium alloy core hard aluminum wire is outstanding, compares the ordinary steel core aluminum stranded wire and reduces line loss more than 8%.
