Higher Conductivity AAAC Overhead Line Conductor , Transmission Line Conductor

AAAC ASTER Conductor BS EN 50183

Used for overhead electrical distribution and transmission line.
 

AAAC ASTER Conductor 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.

AAAC ASTER Conductor 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.

AAAC ASTER Conductor 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.
