ACAR-All Aluminium Conductors Alloy Reinforced

Application

ACAR (Aluminum Conductor Alloy Reinforced) is an overhead transmission conductor made of aluminum and aluminum alloy conductors twisted together, with aluminum alloy wire replacing the traditional steel core. Its structure is usually an aluminum alloy wire in the center and a pure aluminum wire on the outside, or vice versa, to achieve a better balance of conductivity and strength.

ACAR combines the excellent conductivity of pure aluminum with the high mechanical strength of aluminum alloy. Compared with the common ACSR (aluminum steel core stranded wire), it has lighter weight, higher corrosion resistance and better thermal stability.

Because its structure has no steel core, it avoids electromagnetic interference and corona effect, and is suitable for areas with high interference requirements, such as urban power grids, airports and communication lines.
