All aluminum alloy conductor

1.Applications:

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.The inductive effect of the ACSR's steel core is eliminated, hence increasing the operating efficiency of the line.

2.Features and Benefits:

Aluminum alloy conductors have a number of advantages over the use of the ACSR or all aluminum conductors. Lower power losses than for equivalent single aluminum-layer ACSR conductors. (The inductive effect of the steel core in the ACSR is eliminated).

• Simpler fittings than those required for ACSR.

• Excellent corrosion resistance in environments conducive to galvanic corrosion in ACSR.

• Strength and sag approximately the same as for equivalent 6/1 and 26/7 ACSR conductors.

•Outside diameters are the same as for standard ACSR conductors, permitting interchangeability of fittings.

• Greater resistance to abrasion than that for 1350 wires in all-aluminum or ACSR conductors.

Key Benefits:

· High tensile strength as compared to AAC conductor.

· Higher conductivity as compared to ACSR conductor.

· Better corrosion resistance than ACSR conductor.
