Product Detail
Used for overhead electrical distribution and transmission line. We have obtained certificates of ISO9001, ISO14001.

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.

(3)AAAC (All Aluminum Alloy Conductor) referred to conductors have higher strength but lower conductivity than pure aluminum. 

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)Being lighter, alloy conductors can sometimes be used to advantage in place of the more conventional ACSR.

(4)Having lower breaking loads than the latter, their use becomes particularly favourable when ice and win loadings are low.

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.

• 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.

• High tensile strength as compared to AAC conductor.

• Higher conductivity as compared to ACSR conductor.
