Conductors
The group manufactures various types of Aluminium Conductors catering to the Power Sector. It finds its use in the overhead line conductors for the transmission of electricity. They may or may not have reinforcement based on its end use. We have facilities to produce Aluminium strands upto 61 strands with individual wire diameters ranging from 1.60mm to 8.00mm. We manufacture AAC, AAAC and ACSR with various packing options including coils, wooden drums and steel drums to meet our customer requirement.
AAC (All Aluminium Conductor)
Key Benefits of AAC is:
- High corrosion resistance of AAC due to homogenous construction making it ideal for coastal areas.
- Conductivity of AAC is high. It has the highest conductivity to weight ratio in overhead conductors.
- For the same specific resistance, weight of AAC is lesser than copper even with a higher cross-sectional area. This makes it transportation and erection friendly.
We offer AAC conductor as per:
- IS 398 Part I
- BS 215 Part I
- DIN 48201-5
- IEC 207
- ASTM B231
AAAC (All Aluminium Alloy Conductor)
Having superior mechanical properties, AAAC does not have any need for steel reinforcements. Hence for the same diameter of conductor, AAAC has a higher conductivity, superior mechanical properties and lower specific weight than ACSR conductors.
Key Benefits of AAAC is:
- Excellent resistance to corrosion
- Superior mechanical properties compared to AAC
- Higher conductivity when compared to ACSR conductors
We have facilities to produce upto 61strand of AAAC with cross-sectional area ranging from 15mm2 to 767mm2. Our product conforms to various international standards like:
- IS 398 Part IV
- BS 3242
- DIN 48201-6
- IEC 61089
- ASTM B399
Aluminium Conductor Steel Reinforced (ACSR)
Proportion of steel and Aluminium in ACSR is decided on the basis of the mechanical strength and current carrying capacity of the conductor. For example, for the same current carrying capacity the amount of steel would be more when used in area with high wind load, ice load etc., when compared to mild weather areas. ACSR is dependable and economical. Its high mechanical strength to weight ratio enables longer spans with fewer supports and lesser sag. With reduced number of supports, there is lesser foundation cost, erection cost, hardware, fittings etc. Further due to its large diameter, corona losses are low resulting in substantial savings in high voltage lines.
Key Benefits of ACSR is:
- High tensile strength and High mechanical strength to weight ratio
- Low corona effect
- Better sag properties
- Economic and best suited for transmission lines with long spans.
With facility to produce core wire within the group and processing ACSR upto 61 strands, we manufacture ACSR complying with various international standards including:
- IS 398 Part II & V
- BS 215 Part 2
- DIN 48204
- IEC 209
- ASTM B232
