هادی آلومینیومی با مغزی آلیاژ آلومینیومی (ACAR)

The ACAR conductor consists of H1350 aluminum wires with T81 6201 aluminum alloy in the center. Aluminum alloy is usually present in the center of the conductor, but in designs, it can be placed in the same layers as aluminum wires. Due to the use of aluminum alloy, this conductor has higher strength compared to AAC conductor under conditions of the same diameter, but it has higher electrical resistance and the maximum passing current is lower. Compared to the ACSR conductor, this conductor has lower electrical resistance and higher maximum allowable passing current in the condition of the same diameter, but its tension-to-weight ratio is lower and it will increase the wire Sag and decrease the span of the masts.

Therefore, in cases where the allowed passing current has a higher degree of importance than the span distance, the ACAR conductor can be used.
