ACSR conductor consists of a solid or stranded steel core surrounded by strands of aluminum (E.C. GRADE). ACSR Conductor is available in a wide range of steel, containing carbon from 0.5% to 0.85 %. The higher strength ACSR Conductor are used for river crossings, overhead ground wires, installations involving extra long spans etc. Against any given resistance of conductor, ACSR may be manufactured for having a wide range of tensile strength as per requirement. The principal advantage of these conductors are high tensile strength so that they are used for longer spans with less supports. Due to the greater diameter of ACSR Conductor a much higher corona limit can be obtained causing big advantages on high as well as extra high voltage Overhead lines.
The key benefit of ACSR Conductor is its high tensile strength.
ACSR conductors is most commonly used by power distributing companies:
9.5mm diameter E.C. Grade Aluminium Rod is drawn into the required Diameter on Slip Type Wire Drawing Machine and it undergoes tests like Breaking Load, Resistance, Diameter Surface Finish, Wrapping Test etc.
ISI marked HTGS Wire are checked as per suppliers certificate. If required,tests are done in lab.Quality ‘OK’Material goes to spooling operation.
In case of Small Conductors i.e Conductors not having more than seven strands, center wire of HTGS Wire will be starnded with six Aluminium wire around steel wire in Tubular Machine.
In case of Multi Layer Conductor, seven HTGS Wire are stranded in Tubular Machine and the same stranded core wire is again stranded with Aluminium wire in Multi Strand Machine in the required Wooden Drum. Packing & stencling is done as per IS-398 Part–2.
