subject: Electrical Wiring With Aluminium And Copper [print this page] Copper wiring is the mostly used wiring in electrical, the main reason being its high electrical conductivity. Its high conductivity allows the electricity to pass through it without being much heated up. Because of high cost of copper wire, aluminum wires are being used in its place. The low cost of aluminium wire make them the popular in electrical wiring.
Aluminium conductor has been widely used in power distribution and large feeder circuits. Aluminium being cost effective serves as a good alternative to large feeder circuits for heavy current loads. Since, earth has abundant deposit of aluminium there is no issues in its availability. From 1960s to 1970s, aluminium wire had been widely used in the North American housing wiring.
Aluminium has the greatest resistivity hence it requires larger conductors in comparison to copper wiring. Originally aluminium conductors were used with wiring device for copper wires but this resulted in defected connections. Later the standard of wiring devices was revised. Many devices came to address problems associated with junctions between dissimilar metals, mechanical and oxidization effects with increase in temperature; the devices being receptacles, switches, breakers, splice connectors, etc. However nowadays many alloys of aluminium are being used to curtail is shortcomings, as a result the use of aluminium is still on.
Copper Tinned Wire are becoming more and more famous day by day; rubber has many disadvantages such as when light fixtures or switches are replaced; tightening connections cause insulation to flake off conductors. Rubber-insulated cables tend to become brittle as a result of exposure to oxygen; copper tinned wire is now used in its place. Apart from this, rubber is hard to separate from copper. Copper Tinned Wire has become a popular alternate it is used as overhead power source in light, subways and heavy transit systems.
Copper has become the most used metal for electrical purposes. It has certain special properties that set it apart from other metals. There are many different kinds of wires derived from copper. Braided Tinsel Wire is a low voltage electrical wire made-up of copper; this is done by wrapping a number of copper foil strands around textile core. Braided Tinsel Wire has become very popular for power distribution. Copper wires are highly flexible and are known to have resistant against metal exhaustion.
There are a large number of Aluminium Wire Suppliers in India that are providing Aluminium Wire, Braided Tinsel Wire, Copper Tinned Wire and Bunched Tin Coated Wire. There is an increase in the demand of wires and similarly increase is seen in Aluminium Wire Suppliers and manufacturers as more aluminum alloys are being developed and used in electrical wirings now.
