( Industry news] Cable aluminum package the difference between the steel core aluminum stranded wire and steel core aluminum stranded wire atltech P cable aluminum package the difference between the steel core aluminum stranded wire and steel core aluminum stranded wire aluminum package the difference between the steel core aluminum stranded wire and steel core aluminum stranded wire, lies in their different steel core. Steel reinforced steel core aluminum stranded wire is made of galvanized steel wire stranding. Aluminum package aluminum clad steel wire in the steel core aluminum stranded wire is a kind of double wire. It USES high temperature and high pressure will be electrical aluminium continuous extrusion cladding on high strength steel wire, steel aluminium about um thickness is formed between aluminum and steel combined with permeable zone. Aluminum cladding layer of steel wire after light after repeated drawing of double metal deformation of synchronous machine, aluminum and steel with proportional deformation, make aluminum steel combined with permeable zone more homogeneous solid. Aluminum package steel reinforced aluminium conductor relative to the steel core aluminum stranded wire: what are the characteristics, mechanical and electrical characteristics of aluminum steel core aluminum stranded wire and steel core aluminum stranded wire structure and mechanical properties are the same size, but aluminum package weight per unit length of steel core aluminum stranded wire is lighter steel core aluminum stranded wire about %. Can be concluded from this, the two levels of wind load is the same, but the former vertical load about % less than the latter. Aluminum package steel core aluminum stranded wire ℃ when the dc resistance of the steel core aluminum stranded wire about. %; Aluminum package guarantee breaking force calculation of steel core aluminum stranded wire was lower than those of steel core aluminum stranded wire. %。 And corrosion resistance overhead conductors in the atmosphere by electrochemical corrosion. In the steel core aluminum stranded wire and coating on the surface of the steel core and aluminum wire contact form electrochemical corrosion, because of potential less than aluminum, plating results corrosion coating was quickly, make the steel core is exposed to the atmosphere and corrosion. In addition, the coating had been corrosion, the steel core and aluminum wire contact and electrochemical corrosion, formation of aluminium potential is lower than iron, aluminium wire and eroded. For aluminum wrapped steel core aluminum stranded wire, because the aluminum clad steel wire chinalco, there is good metallurgical combination between steel stranded wire in each are aluminum contact between monofilament, they don't exist between different metal electrochemical corrosion, so can greatly reduce the corrosion rate of wire, so as to extend its service life. Corrosion resistance is, as it were, aluminium bag the greatest advantages of steel core aluminum stranded wire.
