Aluminium Conductors Steel Reinforced (ACSR conductors), as their name suggests, consist of a solid or stranded steel core surrounded by strands of Electrolytic grade aluminium. The steel core imparts high mechanical strength to ACSR conductors, which are therefore suitable to be used for river crossings, overhead transmission lines, installations involving extra long spans etc. For any given resistance, ACSR conductors can be manufactured having a wide range of tensile strength as per customer requirements. The principal advantages of these conductors are high tensile strength and high mechanical strength to weight ratio, and therefore they are used for longer spans with fewer supports and lesser sag at a given tension. ACSR is preferred for it’s capacity to withstand extreme wind loads. Due to the greater diameter of ACSR conductors corona losses are low, resulting in substantial savings in high as well as extra high voltage overhead transmission.
> ACSR conductors have high tensile strength.
> High mechanical strength to weight ratio.
We normally manufacture ACSR Conductor as per following standards.
> BS 215 Part 2
> DIN 48204
> IEC 209
> ASTM B232 : 1981
> IS 398 Part 2
Used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing capacity.
