Abstract
The utility model discloses an energy-saving high-strength aluminium alloy twisted insulated cable, comprising a plurality of layers of energy-saving high-strength aluminium alloy wire layers stranded concentrically. A shielding layer and an insulating layer are disposed outside the energy-saving high-strength aluminium alloy wire layers in sequence. Thickness of the shielding layer is 0.31-0.51 cm, and thickness of the insulating layer is 0.71-1.21 cm. Compared with an ordinary cable, the e energy-saving high-strength aluminium alloy twisted insulated cable is wrapped with a plurality of layers of energy-saving high-strength aluminium alloy wires, and conductivity of aluminium alloy single lines in the layers is 55% IACS, and the conductivity is improved by 2.5% IACS compared with the ordinary cable. Tensile strength is more than 295 MPa. Overall energy-saving effect of the energy-saving high-strength aluminium alloy twisted insulated cable is outstanding. Compared with an ordinary insulated cable, line loss is reduced by more than 3.5%. The cable has greater strength, larger span, utilization amount of poles is reduced, line loss is reduced, and engineering investment is saved.
Description
Technical field
The utility model relates to a kind of energy saving high degree aluminium alloy 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 saving high degree aluminium alloy 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 saving high degree aluminium alloy stranded conductor insulated cable, comprise the energy saving high degree aluminium alloy wire layer that multilayer concentric is stranded, and described energy saving high degree aluminium alloy wire layer periphery is provided with screen and insulating barrier successively; Described shielding thickness is 0.31-0.51cm, and described thickness of insulating layer is 0.71-1.21cm.
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, five layers at the most at least.
The beneficial effects of the utility model: energy saving high degree aluminium alloy stranded conductor insulated cable is compared common cable, the single line conductance of the multi-layer energy-saving high-strength aluminum alloy line layer that coats is 55%IACS, compare the rolled products of ordinary high-strength aluminium alloy wire and improve 2.5%IACS, more than the tensile strength 295MPa.The energy-saving effect of overall energy saving high degree aluminium alloy stranded conductor insulated cable is outstanding, compares common insulated cable and reduces line loss more than 3.5%, and its intensity is bigger, and span is bigger, reduces tower bar consumption, reduces line loss, saves construction investment.
