ACSR TP Twisted Pair Conductors FAQ Sheet
Do you publish a chart that shows the SIW conductors, number of strands, and diameters of your cables? The minimum SIW wires for 2/0 is 11, but I have a piece of Alcan 2/0 conductor and the wire count is 13.
SIW conductors allow a range of strands in each size of conductor.
On one of our projects we need to run a 4.16kV, 0.7mi, overhead power line that carries about 2000A. What size of ACSR (or ACSS) conductor will I need to carry the required load and to limit the voltage drop to 3%? Are there any disadvantages to using ACSS conductor?
The proper selection of a conductor can only be made taking into account the line design. For 2000 amps, a bundled ACSR configuration would have to be evaluated to achieve the needed ampacity, which would probably be in the range of a 1590 kcmil conductor. As for an ACSS, you can find listed ampacity values in our ACSS product brochure, which is located on our website on the
ACSS product page. Of course, these capacities are at the listed conditions. If the conditions change, the ampacity can change. ACSS conductors are installed similar to ACSR. Extra care needs to be taken due to the annealed aluminum strands. Please reference our
ACSS installation guidelines for further information.
We use PLS CADD software to design conductors which can design ACSR-SD type conductors, but we would like to carryout validation design. Can you advise us on where to find other software that is capable of designing Alcan SD conductors?
Currently, there is no software available commercially to design SD conductors.
