AAAC Cables

All Aluminium Alloy Conductor (AAAC) is made from aluminum-magnesium-silicon alloy of high electrical conductivity containing Magnesium (0.6-0.9%) & Silicon (0.5-0.9%) Aluminium Alloy 6201 with minimum conductivity is the most preferred choice of matrial for this type of conductor. The 6201 Alloy rod of 9.5mm diameter is drawn to an intermediate size and coiled. The coil is thereafter placed in a large electrically heated furnace with forced air circulation. The coil is soaked at predetermined temperature for a fixed period of time wherein the precipitated alloying elements are brought back into solution and thereafter it is frozen in solution by quenching the coil in water without allowing the alloying elements to re-precipitate. The solutionised coil is dried and further drawn down to the final size for manufacturing the required AAAC. The solutionised coil is given time to attain required strength and care is taken to ensure that the solutionised coil does not harden more than the prescribed limit.
