AAA Conductor

All Aluminium Alloy Conductors

Introducing our AAAC conductors, the epitome of lightweight strength in electrical transmission. Crafted from high-strength aluminium alloy strands, our AAAC conductors offer exceptional conductivity while remaining significantly lighter than traditional conductors. This combination of strength and weight savings makes AAAC conductors an ideal choice for overhead power lines, allowing for easier installation and reduced stress on support structures. When it comes to delivering uninterrupted power with efficiency and reliability, our AAAC conductors are the smart choice for today's electrical infrastructure.

The use of AAAC is increasing fast for transmission and distribution purposes and is now gradually replacing AAC/ACSR due to its various advantages over traditional AAC / ACSR Conductors. The main features of AAAC are reduced line losses, increased span. Longer life, homogeneous character and its anticorrosion properties. AAA Conductors is a new concept for energy conservation.

AAAC exhibits excellent corrosion resistance especially in sea coast areas and in polluted industrial areas due to absence of steel core.

Since MAC is homogeneous (with strands of Aluminium Alloy) with no steel component the resistance of AAAC is lower as compared to ACSR.

AAAC can carry at least 15-20% extra current as compared to ACSR of equal size.

Experience in foreign countries shows that All Aluminium Alloy Conductors are in service for over 60 years, which is about double the life of ACSR Conductors.

The surface hardness of AAAC is 80 BHN as compared to 35 BHN of ACSR.

This reduces the damage to surface during handling and therefore leading to lesser corona losses and ratio interference at EHV.

AAAC are stable up to 90 C against ACSR conductors which are stable up to 75 C.

Since AAAC has higher strength to weight ratio, span can be increased from 2 to 15% as in case of ACSR resulting in overall reduction of cost in towers supports and other accessories in transmission line system.

A.A.A.C. are mainly used for overhead lines, in transmission and distribution electrical networks, having relatively long spans. They are also used a messenger to support overhead electrical cables.
