Aluminum conductor steel reinforced is widely used in overhead transmission line for primary and secondary distribution. It is manufactured of one or more aluminum as outer wire & wire stranded with zinc coated high strength steel core wire. Aluminum conductor steel reinforced is manufactured as per BS-2l5 (part-II), ASTM B-232, DIN-48204 and IEC standard. It provides excellent mechanical strength without compromising the ampacity. These type of conductors provide excellent design benefit for extra long spans, river crossing.
