AAAC ( All Aluminium Alloy Conductors )

Concentric lay stranded Aluminium Alloy Conductors (AAAC) are made out of high strength Aluminium-Magnesium-Silicon Alloy. Midal manufactures and supply AAAC with different variants of electrical grade alloy type and . one or more strands of hard drawn aluminium alloy.

Goto Mingda to know more.

These conductors are designed to get better strength to weight ratio and offer improved electrical properties, excellent sag-tension characteristics, and superior corrosion resistance when compared with ACSR. As compared to a conventional ACSR conductor, the lighter weight, comparable strength & current carrying capacity, lower electrical losses and superior corrosion resistance have given AAAC a wide acceptance in the distribution and medium & high voltage transmission lines..

Midal can manufacture & supply AAAC on Non returnable wooden/steel reels or Returnable steel reels.

Features

• high strength to weight ratio
• better sag characteristics
• improved electrical properties
• excellent resistance to corrosion

Specifications

AAAC manufactured by Midal meets or exceeds the requirements of all international standards like ASTM, AS, BS, CSA, DIN, IEC, NFC, SS -etc

AAAC / All Aluminum Alloy Conductor

Overhead Conductor, Overhead Transmission Line

Application
Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high-strength aluminum-alloy to achieve a high strength-to-weight ratio; affords good sag characteristics.

• 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.
• The aluminum alloy conductors are used in replace of single-layer ACSR conductors to reduce power loss in overhead distribution and transmission lines,when replacing the aluminum conductor steel reinforced , the AAAC can save 5-8% of the construction cost.
• AAAC referred to have higher strength but lower conductivity than pure aluminum Being lighter, alloy conductors can sometimes be used to advantage in replace of the more conventional ACSR.

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 wires in all-aluminum or ACSR conductors.
• High tensile strength as compared to AAC conductor.
• Higher conductivity as compared to ACSR conductor.
