Aluminum building wiring is a type of electrical wiring for residential construction or houses that uses aluminum electrical conductors. Aluminum provides a better conductivity-to-weight ratio than copper, and therefore is also used for wiring power grids, including overhead power transmission lines and local power distribution lines, as well ...
Terminal blocks for joining aluminium and copper conductors. The terminal blocks may be mounted on a DIN rail. Aluminium wire was common in North American residential wiring from the late 1960s to mid-1970s due to the rising cost of copper. Because of its greater resistivity, aluminium wiring
Aluminium alloys are often used due to their high strength-to-weight ratio, corrosion resistance, low cost, high thermal and electrical conductivity.There are a variety of techniques to join aluminium including mechanical fasteners, welding, adhesive bonding, brazing, soldering and friction stir welding (FSW), etc. Various techniques are used based on the cost and strength required for the joint.
A thermite weld in progress. Exothermic welding, also known as exothermic bonding, thermite welding(TW),[1]and thermit welding,[1]is a weldingprocess that employs molten metal to permanently join the conductors. The process employs an exothermic reactionof a thermitecomposition to heat the metal, and requires no external source of heat or current.
A copper strip is formed into the shape of a cylinder, while it is being wrapped around an aluminum core and the edges of the copper strip are welded together. The assembly is then pulled through a die, where the cladded wire is squeezed and stretched while also improving the bonding between the copper and the aluminum core. [1]
Twist-on wire connectors. Twist-on wire connectors are a type of electrical connector used to fasten two or more low-voltage (or extra-low-voltage) electrical conductors. They are widely used in North America and several European countries in residential, commercial and industrial building power wiring, but have been banned in some other ...
Soldering. Desoldering a contact from a wire. Soldering (US: / ˈsɒdərɪŋ /; UK: / ˈsoʊldərɪŋ /) is a process of joining two metal surfaces together using a filler metal called solder. The soldering process involves heating the surfaces to be joined and melting the solder, which is then allowed to cool and solidify, creating a strong ...
Copper is the electrical conductor in many categories of electrical wiring. [ 3 ][ 4 ] Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment. [ 5 ] Copper and its alloys are also used to make electrical contacts.
