The Top Aluminium Conductors in Kolkata

Group Nirmal, established in Kolkata, is a renowned manufacturer of the top aluminium conductors in Kolkata and is also among the leading aluminium conductor manufacturers in India. Aluminium conductors are crafted for efficient electrical transmission. The variety includes AAC, AAAC, and ACSR, with several packaging options. 61 strands of aluminium with diameters ranging from 1.6mm to 8mm are available.

AAC (All Aluminium Conductor)

Among aluminium conductor manufacturers, Group Nirmal is a trusted name for the top aluminium conductors in Kolkata, especially in manufacturing All Aluminium Stranded Conductor, popularly known as All Aluminium Conductor (AAC). It is made up of electrolytically refined aluminium with a minimum of 99.95% purity and about 1350 strands. It finds use in various overhead voltage lines.

Characteristic Features and Advantages –
• High conductivity
• High corrosion resistance, making it long-lasting
• High flexibility

All Aluminium Alloy Conductors (AAAC)

The main difference between AAC and AAAC is in the material used. AAAC comprises an aluminium-magnesium-silicon alloy, providing high conductivity. These conductors are commonly made out of aluminium alloy 6201. The absence of a steel core ensures high corrosion resistance. Steel is of higher strength than aluminium.

Characteristic Features and Advantages –
• Better mechanical properties and improved electrical conductivity
• Tremendous corrosion resistance and potency-to-weight ratio

Aluminium Conductor Steel-Reinforced Cable (ACSR)

Low weight, low cost, resistance to corrosion, and decent mechanical stress resistance are the prominent features of ACSR. This category of top aluminium conductors in Kolkata is composed of EC-grade aluminium. The standard steel core used is made of galvanized steel. Steel is of higher strength than aluminium. Numerous sizes with multiple steel centers are obtainable.

Characteristic Features and Advantages –
• Outstanding transmission
• Well suited for long-span transmission lines
• Significant tensile strength
• Pocket friendly
