All Aluminium Conductor (AAC )

AAC are used in overhead electric power transmission and distribution lines with various grade voltages.

  • Description

1.Performance

The rated tensile strength of AAC is denoted with the result of total cross-section of all aluminum conductors multiplied by min.tensile of corresponding size specified in the standard for aluminum wire.

2.Applications

All Aluminium Conductor has the characteristics of simple structure, convenient erection and maintenance, low line cost , so it is widely used in overhead transmission and distribution lines of various voltage levels.

3.Standards

All Aluminum Conductor meets or exceeds the following standards: IEC61089, BS215 part1, DIN48201 part5, ASTMB231, BS EN50182, GB/T 1179-2008.
