AAAC Bare Overhead Conductor

STANDARD:ASTM B399, BS 3242, BS EN50183, DIN 48201, IEC 61089, etc
CAPACITY:2000tonmonth
AAAC aluminum alloy conductors are extensively used for overhead distribution and transmission lines adjacent to ocean coastlines where there can be a problem of corrosion in the steel of an ACSR construction due to the following features:
1.high strength to weight ratio
2.better sag characteristics
3.improved electrical properties
4.excellent resistance to corrosion
5.higher operating efficiency of the line
Aluminum alloy conductors have a number of advantages over the use of the ACSR or all-aluminum conductors.
1.Lower power losses than for equivalent single-aluminum-layer ACSR conductors.(The inductive effect of the steel core in the ACSR is eliminated.)
2.Simpler fitting than those required for ACSR.
3.Excellent corrosion resistance in environments conductive to galvanic corrosion in ACSR.
4.Strength and sag approximately the same as for equivalent 61 and 267 ACSR conductors.
5.Outside diameters are the same for standard ACSR conductors, permitting interchangeability of fitting.
6.Greater resistance to abrasion than that for 1350 wires in all-aluminum or ACSR conductors.
