AAC, AAAC, ACSR, AACSR& ACAR conductor widely used in power transmission lines with various voltage levels. Since they have such good characteristics as simple structure, convenient installation and maintenance, low cost for the line, large transmission capacity and are also suitable for laying across rivers and valleys where special geographical teatures exist. 1. Specification: (1) all aluminium conductor (AAC) (2) all aluminimum alloy conductor(AAAC) (3) aluminum conductor steel reinforced (ACSR) (4) anti-corrosion type ACSR (5) aluminimum conductor aluminimum clad steel reinforced(ACSR/AW) (6)rear earth aluminimum conductor steel reinforced(ACSR/RE) (7)aluminimum conductor aluminimum alloy reinforced(ACAR) 2. Elative manufacturing standards: IEC83, IEC1089, 31, B232, BS215, DIN48204. 1). Standard: IEC61089, BS215 part2, ASTM B232, DIN48204, BS EN50182. 2). Specification: ACSR is composed by bare concentric-lay-stranded galvanized steel wire(s) with aluminum wires surrounded by one or more layers of helically. Greased ACSR can also be supplied. 3). Application: ACSR is widely used in overhead electric power transmission and distribution lines with various voltage levels.
