Abstract
The utility model discloses an energy-saving round aluminum conductor steel reinforced insulated cable. The energy-saving round aluminum conductor steel reinforced insulated cable comprises steel cores and at least two layers and at most four layers of energy-saving round aluminum wires which are concentrically stranded at the periphery of the steel cores; the exterior of the energy-saving round aluminum wires is provided with a shielding layer and an insulating layer successively; the thickness of the shielding layer is in a range of 0.05 to 0.09 cm; and the thickness of the insulating layer is in a range of 0.1 to 0.25 cm. Compared with an ordinary cable, the energy-saving round aluminum conductor steel reinforced insulated cable is advantageous in that the electrical conductivity of a single wire in the plurality of energy-saving hard aluminum wire layers coated at the periphery of the steel cores is 63% IACS and is improved by 2% IACS compared with an ordinary aluminum wire; the saving-energy effect of the energy-saving round aluminum conductor steel reinforced insulated cable is excellent, and line loss of the energy-saving round aluminum conductor steel reinforced insulated cable is decreased more than 3.28 % compared with an ordinary steel core/aluminum wire stranded cable.
Description
Technical field
The utility model relates to a kind of energy-conservation steel core circle aluminium stranded conductor insulated cable.
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 lead unit are is very important with regard to what show.At present, the employed lead 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 subjected to certain restriction.
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.Aluminium alloy core aluminium stranded conductor line is littler than same specification ordinary steel core aluminum stranded wire resistance, transmission line capability is big, in light weight, intensity is high, based on these advantages, the use amount of aluminium alloy conductor increases year by year.
The utility model content
The utility model purpose is to provide a kind of energy-conservation steel core circle aluminium stranded conductor insulated cable at the defective that prior art exists.
The scheme that adopts for achieving the above object is: a kind of energy-conservation steel core circle aluminium stranded conductor insulated cable, comprise steel core and with one heart strand is at two-layer at least, four layers the energy-conservation round aluminum steel layer at the most of described steel core periphery, described energy-conservation round aluminum steel layer periphery is provided with screen and insulating barrier successively; Described shielding thickness is 0.05-0.09cm, and described thickness of insulating layer is 0.1-0.25cm.
Preferably, described steel core is made of a galvanized steel wire.
Preferably, described steel core is that a galvanized steel wire and Duo Gen twist the multilayer heart yearn that the galvanized steel wire in this galvanized steel wire periphery constitutes with one heart.
Preferably, described steel core is at most three layers, and adjacent layer strand is on the contrary.
Preferably, described energy-conservation round aluminum steel layer comprises many single lines of the same size; The adjacent layer of described energy-conservation round aluminum steel layer strand is on the contrary, and outermost layer twists to being dextrad.
The beneficial effects of the utility model: energy-conservation steel reinforced aluminium conductor insulated cable is compared common cable, and the conductance of single line is 63%IACS in the peripheral multi-layer energy-saving hard-drawn aluminium wire layer that coats, and compares common aluminum steel and improves 2%IACS.The energy-saving effect of overall energy-conservation steel reinforced aluminium conductor insulated cable is outstanding, compares ordinary steel core aluminum stranded wire insulated cable and reduces line loss more than 3.28%.
Description of drawings
