Abstract
The utility model discloses an energy saving high strength aluminum alloy-cored aluminum stranded conductor insulation cable comprising energy saving high strength aluminum alloy cores and at least two, at most four energy saving aluminum stranded conductor layers disposed on outer sides of the energy saving high strength aluminum alloy cores. Each of the energy saving aluminum stranded conductor layers is formed by arranging a plurality of energy saving aluminum stranded conductors on the energy saving high strength aluminum alloy cores radially in a circumference around the energy saving high strength aluminum alloy cores, and is intertwisted with the energy saving high strength aluminum alloy cores concentrically. The outermost layer of the energy saving aluminum alloy stranded conductor layers 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 0.5 cm, and the thickness of the insulation layer is in a range from 0.7 to 1.2 cm. The energy saving high strength aluminum alloy-cored aluminum stranded conductor insulation cable is advantageous in that compared to common cables, the aluminum alloy cores are much lighter than the steel cores, and are provided with good conductive performance; compared to common aluminum alloy cores, the conductivity of each of the energy saving high strength aluminum alloy cores can reach 55%IACS, which is increased by 2.5%, therefore the effect is obvious.
Description
Technical field
The utility model relates to a kind of energy saving high degree aluminium alloy core, aluminium molded lines strand 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 core, aluminium molded lines strand insulated cable at the defective that prior art exists.
The utility model for achieving the above object, adopt following technical scheme: a kind of energy saving high degree aluminium alloy core, aluminium molded lines strand insulated cable, comprise energy saving high degree aluminium alloy core and be located at energy saving high degree aluminium alloy core outer at least 2 layers, 4 layers energy-conservation aluminium molded lines layer at the most, described energy-conservation aluminium molded lines layer radially is circle-shaped encirclement by some energy-conservation aluminium molded lines along described energy saving high degree aluminium alloy core and is arranged on the energy saving high degree aluminium alloy core, and twists together with described energy saving high degree aluminium alloy core concentric-ring pattern; Described energy-conservation aluminium molded lines layer outermost layer also 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, the adjacent layer of described energy-conservation aluminium molded lines layer strand is on the contrary, and the outermost layer strand is to for to the right.
Preferably, the contact-making surface of adjacent energy-conservation aluminium molded lines is plane or zigzag face in the described energy-conservation aluminium molded lines layer.
Preferably, described energy saving high degree aluminium alloy core is made of an energy saving high degree aluminium alloy wire or twists the multilayer heart yearn that the energy saving high degree aluminium alloy wire in this energy saving high degree aluminium alloy wire periphery constitutes with one heart by an energy saving high degree aluminium alloy wire and Duo Gen.
Preferably, described energy-conservation aluminium molded lines is T shape aluminium molded lines or Z-shaped aluminium molded lines.
The beneficial effects of the utility model: energy saving high degree aluminium alloy core, aluminium molded lines strand insulated cable is compared common cable, aluminium alloy core is compared light many of steel core, possesses good conductive capability again, and energy saving high degree 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.Molded lines is stranded closely, and the activity coefficient height can effectively increase the transmission of electricity cross section, promotes transmission capacity.The energy-saving effect of overall energy saving high degree aluminium alloy core, aluminium molded lines strand insulated cable is outstanding, reduces line loss more than 8%.
