Aluminum Wire as an Electrical Conductor

Aluminum wire has been used as an electrical conductor for a many years. Shortly after the beginning of modern power distribution systems being constructed in the late 1880s, electrical utilities started to use aluminum wire for power transmission lines. Aluminum has been safely and effectively used in electrical applications in the United States for more than 100 years.

Aluminum wire is an economical alternative to copper wire. It requires a larger wire gauge than copper wire to carry the same current, however it takes only one pound of aluminum wire to equal the current-carrying capacity of two pounds of copper making it an extremely attractive material for utilities, builders and others.

Aluminum building wiring is a type of electrical wiring used for residential construction or houses that use aluminum electrical conductors. Stranded aluminum cable is another aluminum material that is used for main distribution wiring or feeder lines. Aluminum is very reliable making it a frequently used material when it comes to providing power to your home.

Aluminum wire provides a better conductivity to weight ratio than copper, and therefore is also used for wiring power grids including overhead power transmission lines, local power distribution lines, and power wiring of some airplanes.

Aluminum wiring is an excellent wiring choice when used in the correct application and is properly installed and maintained. Aluminum wire is a great conductor of electricity. It is light weight, strong, and more economical than copper. If you are unsure how to use electrical aluminum wiring, you can contact us for more information or your local licensed electrician.
