Specifications

1.Construction:

(1)All Aluminium Alloy Conductors are generally made out of aluminium alloy 6201.

(2)Standard 6201-T81 high strength aluminum conductors, conforming to ASTM Specification B-399, are concentric-lay-stranded, similar in construction and appearance to 1350 grade aluminum conductors.

2.Application

(1)AAAC 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.

(2)The aluminum alloy conductors are used in place of single-layer ACSR conductors to reduce power loss in overhead distribution and transmission lines.

3.Features

Aluminum alloy conductors have a number of advantages over the use of the ACSR or AAC(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.

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

• High tensile strength as compared to AAC conductor.

• Higher conductivity as compared to ACSR conductor.
