Aluminum in Electric Power

Aluminum wires, aluminum coil strips, aluminum tubular bus bar, aluminum flat bus bar, CCA etc., have been widely used in the field of electric power, such as cables, electrical motors, electrolytic capacitors, transformers, radiators, etc.

The high structural strength, light weight, good electrical conductivity, high ductility, and non-magnetic properties of aluminum make aluminum and its alloys indispensable materials for the power industry. Main application areas include cables, bus bars, overhead transmission lines, motors, foil windings, electrolytic capacitors, transformers, heat sinks and more.

Application of aluminum wire in power field

Aluminum conductor

AAC/All aluminum conductor

AAC is a concentric-lay-stranded conductor consisting of aluminum alloy 1350-H19 wires available in both single-layer and multi-layer constructions.

This all aluminum conductor is a kind of aluminum product made through stranding aluminum wires. It is used for the electricity distribution lines with short span length and small load-carrying capability of the pole.

Aluminum Conductor

The AAC provides reliable performance for overhead power transmission and distribution lines. This standard covers hard drawn round aluminum wires for electrical purposes, which are used as hard drawn stranded aluminum cables and aluminum conductor steel reinforced composite wires.


ASTM B 231, BS 215 Part 1, IEC 61089, DIN 48201, CSA C 49, JIS C 3109, etc.

ACSR/Aluminum conductor steel reinforced

ACSR is a concentric-lay-stranded conductor consisting of a single core wire or a stranded steel central core with one or more layers of 1350 H19 stranded aluminum wires. The steel core wires are protected from corrosion by galvanizing, aluminum-clad alloy or zinc-5% aluminum mischmetal alloy coating. Standard, high, extra and ultra high strength steel is also available.


ASTM B 232, BS 215 Part 2, IEC 61089, DIN 48204, etc.

High-strength AAAC

6101 6201 aluminum alloy conductors are concentric-lay-stranded, similar in construction and appearance to 1350 grade aluminum conductors. They were developed to meet the needs of overhead applications for economic conductors. This application requires higher strength than grade 1350 aluminum conductors, but no steel core. DC resistance at 20°C of the 6201, 6101 conductors and of the standard ACSR of the same diameter are approximately the same. Overhead transmission conductors of the 6201, 6101 alloys are harder and, therefore, have a greater resistance to abrasion than conductors of 1350-H19 grade aluminum.

Aluminum tubular bus bar: A tubular bus bar mainly using aluminum or aluminum alloy as conductor. The conductivity of aluminum is second only to silver, copper and gold. Although its conductivity is only 2/3 of copper, its density is only 1/1 of copper. Therefore, in order to realize the transmission of the same amount of electricity, the aluminum tubular bus bar often needs to be enlarged and thickened.

In addition, the oxide film on the aluminum surface not only has the ability to resist corrosion, but also has a certain degree of insulation. In addition, the price of aluminum tubular busbar is cheap. For engineering projects with cost requirements, aluminum tubular busbar is still quite widely used in power construction.

Application of clad metal in power field

Copper-aluminum gaskets are mainly used in contact gaskets, conductive connection boards, various high and low voltage power distribution devices, etc.

The surface of the copper-aluminum composite busbar is copper, so the oxidation resistance is the same as that of copper. The mutual lap is the lap of copper and copper, and its electrical life is the same as that of copper busbar when it is energized for a long time. After special process treatment, the creep deformation is small, and the performance is close to that of copper, which overcomes the fatal weakness of aluminum busbar, and has the same reliability as copper busbar.
