Aluminium Conductor-Aluminium Alloy Reinforced (ACAR) combines 1350 and 6201 Aluminium alloy strands to provide a transmission conductor with an excellent balance of electrical and mechanical properties. This conductor consists of one or more layers of 1350-H19 hard drawn Aluminium strands helically wrapped over one or more 6201-T81 Aluminium Alloy wires. The core may consist of one or more 6201 strands depending upon the size of the conductor.The diameters of all wires are the same. Aluminium and Aluminium-Alloy wires can be mixed in the same layer as well.
The primary advantage of the ACAR conductor lies in the fact that all strands are interchangeable between EC and 6201, thereby permitting the design of a conductor with an optimum balance between mechanical and electrical characteristics. In effect, ACAR is a composite aluminium-aluminium alloy conductor which is designed for each application to optimize properties. Inverse ACAR conductors are also available with the harder 6201 aluminium alloy wires being on the outer surface of the conductor and the 1350 aluminium making up the heart of the conductor.
ACAR has got better mechanical and electrical properties as compared to an equivalent conductor of ACSR,AAC or AAAC. A very good balance between the mechanical and electrical properties therefore makes ACAR the best choice where the ampacity, strength, and light weight are the main consideration of the line design. These conductors are extensively used in overhead transmission and distribution lines.
Aluminium Conductors, Aluminium-Alloy Reinforced (ACAR) can be supplied to meet various International Standards as follows :
IEC 61089
ASTM B 524
However, Suraj Cables can also supply a range of alternative designs to meet customer-specified requirements.
