1. Low inductance 2. High capacitance 3. Better voltage regulation 4. Easy maintenance 5. Lead AAAC Manufacture
1.Standard
AAAC conductor, All Aluminum Alloy Conductor is produced by the American standard ASTM-B339.
Other international standard also can be satisfied
And customer special request can be satisfied too.
2.Applications
AAAC,Heat treatment Aluminum Magnesium Alloy is used on transmission line of electric power having large span run for its much higher tensile strength,Although it electrical conduvtivity goes down 10% lower than that of aluminum products.

4.Comparation of three kind of wires AAAC AAC ACSR
compare | Wire Model | Total area | Weight | O.D. | D.C.Resistance | Breaking Load | price |
mm² | kg/km | mm | Ω/km | kN | usd/m | ||
AAAC | 300 | 299.43 | 825 | 22.47 | 0.1118 | 83.63 | 2.75 |
AAC | meadowsweet (ASTM-B231) | 304 | 838 | 22.63 | 0.0948 | 47.03 | 2.34 |
ACSR | hen (ASTM-B231) | 298.07 | 1112 | 22.4 | 0.1201 | 105.34 | 2.36 |
We are easily to be told from the table, when the same area and the similar D.C.Resistance, AAAC is lighter than ACSR and stronger than AAC, Combined with its light cheer weight, the span are able to be larger than acsr.Then the money saved is enough to afford the little expensive part of the price.
