Aluminium Core Steel Reinforced consists of steel core with concentrically stranded EC grade Aluminium wires. The core may consist of single or stranded galvanized steel wires imparting high mechanical strength to the conductor, with class A, B or C zinc coating to offer corrosion protection. This makes it suitable for installations with extra long spans, river crossings, etc. It combines the high tensile strength and ruggedness of steel with lightweight and conductivity of EC grade Aluminium.
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:
