Abstract
The utility model discloses an energy saving steel-cored high strength aluminum alloy stranded conductor insulation cable. The insulation cable comprises steel cores and an energy saving high strength aluminum alloy stranded conductor layer, which is formed by intertwisting the aluminum alloy stranded conductors concentrically together, and is disposed on outer sides of the steel cores. An outer periphery of the energy saving high strength aluminum alloy stranded conductor layer is sequentially provided with a shielding layer and an insulation layer. The thickness of the shielding layer is in a range from 0.3 to 0.5cm, and the thickness of the insulation layer is in a range from 0.7 to 1.2cm. Compared to common cables, the outer periphery of the energy saving steel core high strength aluminum alloy stranded conductor insulation cable is wrapped by the multilayer energy saving high strength aluminum alloy stranded conductor layer, and the conductivity of the single conductor is 55% IACS, which is 2.5% IACS more than that of the common high strength aluminum alloy stranded conductors.
Description
Technical field
The utility model relates to a kind of energy-conservation steel core high-strength aluminum alloy twisted wire 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 high-strength aluminum alloy twisted wire 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 high-strength aluminum alloy twisted wire insulated cable, comprise steel core and concentric strand at the energy saving high degree aluminium alloy wire layer of described steel core periphery, described energy saving high degree aluminium alloy wire layer periphery is provided with screen and insulating barrier successively; Described shielding thickness is 0.3-0.5cm, and described thickness of insulating layer is 0.7-1.2cm.
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 saving high degree aluminium alloy wire layer comprises many single lines of the same size; The adjacent layer of described energy saving high degree aluminium alloy wire layer strand is on the contrary, and outermost layer twists to being dextrad.
Preferably, described energy saving high degree aluminium alloy wire layer one deck, three layers at the most at least.
The beneficial effects of the utility model: energy-conservation steel core high-strength aluminum alloy twisted wire insulated cable is compared common cable, single line conductance in its peripheral multi-layer energy-saving high-strength aluminum alloy line layer that coats is 55%IACS, compares the rolled products of ordinary high-strength aluminium alloy wire and improves 2.5%IACS.The energy-saving effect of overall energy-conservation steel core high-strength aluminum alloy twisted wire insulated cable is outstanding, compares common steel core high-strength aluminum alloy twisted wire insulated cable and reduces line loss more than 3.5%.
