Aluminium alloy cables with high strength, of AL type, based on PN-EN 50182.

They are constructed of twisted wires made of AlMgSi allos in species of EN AW-6101. The used aluminium alloy is of approximately 0.55% magnesium and 0.55% silicon, after plastic deformation and further heat treatment, it has excellent mechanical properties with good conductivity. For this reason, the alloyed cables are a great alternative to popular AFL, as having similar mechanical strength and current-carrying capacity, they are of much less weight and have better resistance to corrosion. In comparison with aluminium products, AAL cables have better suspending characteristics and a strength to weight ration.

AAL (AAAC) cables based on PN-EN 50182 MT-18-01-16

The vast majority of the cables installed in existing overhead power lines can operate at temperatures not exceeding 80°C. This restriction significantly influences on the current-carrying capacity, and prevents from flexible management of transmission in peak usage periods of energy needs. Belonging to the low-overhang, high temperature HTLS cables (high temperature, low sag) of ACSS type are in many cases the best solution allowing to increase energy transmission without loss of mechanical properties of the cable or too large overhang.
