Typical dry type transformers used on commercial projects will vary anywhere from45%to as much as100%premium for the copper over the aluminum windings. Liquid filled transformers such as padmounts or SSTs, currently show a price differential of12-15% for Cu-Cu vs. AL-AL, but this percentage...
aluminium has been regarded as the poor relation to copper as an electrical conductor, but recent advances have meant that it is now an exceptionally high performance product that compares very favourably with copper in terms of mechanical strength, heat stability and thermal conductivity characteristics...

Aluminium vs Copper in power lines Hi, I have a question concerning the use of aluminium in power lines. I know that it's lighter than copper and thus cheaper, which is the main reason we prefer it above copper. But in fact alumunium has a lower conductivity than copper. Why is it th...
Their CFD analysis revealed that the heat transfer and thermal conductivity coefficient increased when a nanofluid is used compared to a pure fluid. 2.2.3 Using CuO nanoparticles Copper oxide (Cuo) based nanofluids have also been widely investigated in the context of heat transfer enhancement for ...
Mathematical model of the remelting process of aluminium thin-walled and fine charge due to convective heat transfer was developed. On the basis of this model, an engineering calculation of the specific process of remelting used aluminium cans in the liquid aluminium stream was also carried out. ...
The effects of annealing on the low-temperature specific heat of UBe13−xAlx were investigated on three single crystals of different size (0.62 mg, 1.64 mg, 5.94 mg; cf. Methods Section). In as-grown state, the small, medium and large crystal show Tc = 0.78 K, Tc...
Evaporated copper phthalocyanine (CuPc) thin films in the form of metal-CuPc-metal sandwich structures have been extensively studied, particularly with regard to their electrical conductivity and its variation on exposure to various gases. In the present work, CuPc thin films doped by prolonged ...
include iron, copper, magnesium, silicon, and zinc. The addition of elements to the aluminum gives the alloy improved strength, workability,corrosionresistance, electricalconductivity, and/ordensity, compared with the pure metallic element. Aluminum alloys tend to be lightweight and corrosion resistant...
