1. Applications These steel reinforced aluminum conductors (AAC and ACSR) have been widely used in power transmission lines with various voltage levels, because they have excellent characteristics, including convenient installation and maintenance and low cost large transmission capacity. And they are also suitable for laying across rivers valleys and the places where special geographical features exist.
2. Product Performance (1). The electrical performance of AAC and ACSR is indicated in DCΩ/km(20oC).The resistivity of the hard aluminum wire for stranded wires is not greater than 28.264 nΩ. m of the international standard value (2). The rated tensile strength of AAC is denoted with the result of the total cross-section of all aluminum conductors multiplied by the main tensile of corresponding sizes specified in the standard for aluminum wire. (3). The rated tensile strength of ACSR is denoted with the sum of all aluminum conductors' tensile strength and steel tensile strength. a. The tensile strength of all aluminum conductors is denoted with the result of all cross-sections of aluminum conductors multiplied by the main tensile strength of corresponding size specified in the standard for aluminum wire. b. The tensile strength of all steel wire is denoted with the result of all cross-sections of steel wires multiplied by the stress at 1% elongation of corresponding size specified in the standard for steel wire.
3. Material Standard (1) The hard aluminum conductor used for AAC and ACSR conforms to the standard GB/T 17048-1997(equivalent to IEC 60889:1987). (2) The zinc coated steel wire used for ACSR conforms to IEC 60888:1987. (3) Production can be arranged according to customers' requirements for material standard etc.
