Abstract
The utility model discloses an energy-saving intermediate strength aluminium alloy stranded conductor insulated cable, comprising energy-saving intermediate strength aluminium alloy cores and energy-saving round aluminium wire layers stranded concentrically outside the energy-saving intermediate strength aluminium alloy cores. A shielding layer and an insulating layer are disposed outside the energy-saving round aluminium wire layers in sequence. The thickness of the shielding layer is 0.1-0.2 cm, and the thickness of the insulating layer is 0.3-0.6 cm. Compared with an ordinary cable, the aluminium alloy cores are much lighter than steel cores, and the energy-saving intermediate strength aluminium alloy stranded conductor insulated cable has good conductivity. Compared with an ordinary aluminium alloy core, conductivity of the energy-saving intermediate strength aluminium alloy cores reaches 60% IACS, and the conductivity is improved by 2% IACS, so effect is much outstanding. Conductivity of the plurality of layers of energy-saving hard-drawn aluminium wires wrapped on the periphery is 63% IACS, and is improved by 2% IACS compared with a common aluminium wire. Overall energy-saving effect of the energy-saving intermediate strength aluminium alloy stranded conductor insulated cable is outstanding, line loss is reduced by more than 7%.
Description
Technical field
The utility model relates to a kind of energy-conservation middle strength aluminium alloy core aluminum stranded 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, requirement in simultaneously also having proposed more to overhead power transmission conducting wire, as the wherein decision-making of transmission line capability, mainly solve from two approach, the one, transmission voltage wherein, the 2nd, transmission current wherein, under the certain prerequisite of voltage, transmission current density wherein, namely wherein the transmission line capability of lead unit are just show very important.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, the intensity, 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 middle strength aluminium alloy core aluminum stranded 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 middle strength aluminium alloy core aluminum stranded wire insulated cable, comprise energy-conservation in the strength aluminium alloy core and with one heart strand described energy-conservation in the energy-conservation round aluminum steel layer of strength aluminium alloy core periphery, described energy-conservation round aluminum steel layer periphery is provided with screen and insulating barrier successively; Described shielding thickness is 0.1-0.2cm, and described thickness of insulating layer is 0.3-0.6cm.
Preferably, described energy-conservation middle strength aluminium alloy core is made of an energy-conservation middle strength aluminium alloy line.
Preferably, described energy-conservation middle strength aluminium alloy core is to twist the multilayer heart yearn that the energy-conservation middle strength aluminium alloy line of strength aluminium alloy line periphery constitutes in this is energy-conservation with one heart by an energy-conservation middle strength aluminium alloy line and Duo Gen.
Preferably, described energy-conservation in the strength aluminium alloy core be at most three layers, 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.
Preferably, described energy-conservation round aluminum steel layer is four layers at the most.
The beneficial effects of the utility model: strength aluminium alloy core aluminum stranded wire insulated cable is compared common cable in energy-conservation, aluminium alloy core is compared light many of steel core, possesses good conductive capability again, and the strength aluminium alloy core is compared the common aluminum alloy core in energy-conservation, conductance reaches 60%IACS, improved 2%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 strength aluminium alloy core aluminum stranded wire insulated cable is outstanding in overall energy-conservation, reduces line loss more than 7%.
