Uses of Aluminium wire
Aluminium wire (also spelled as
aluminum wire), is largely used by domestic, commercial and industrial feeders.
This type of wiring is relatively lighter, cheap and more flexible than its
counterparts (including copper wire). However, aluminium wire can result in
fire and therefore excessive care should be taken towards proper installation
and termination methods and materials. A less cheap, but more effective
alternative is the copper clad aluminium wire (abbreviated as CCAW or CCA). It
is composed of inner core of aluminium and an outer covering of copper. CCAW is
less hazardous than pure aluminium wire and weighs far less than the copper
wire.
Uses of Aluminium wire
In construction industry
Aluminium is an excellent alternative to copper and is largely used in the
manufacture of building wires. Electricians and contractors use large sizes of
aluminium building wire where there is requirement of low voltage. This is more
beneficial to contractors in terms of savings as it has half the weight of
copper wire. Aluminium conductors for building wire are made in such a manner
that the overall diameter of the aluminium wire is similar to that of copper
wire.
In Electrical distribution industry
Utilities such as electrical
distribution companies have been extensively using aluminum wire throughout
their distributing systems (power grids) for transmission of electric current.
In communication industry
The
copper clad aluminium wire is primarily used in high quality coils, power
cables and antennas. The aluminium-copper combination finds its use in
commercial as well as residential applications including household wiring,
cable wiring, headphones, loudspeakers and antennas. CCAW are also used to help
connect the internet to the computer. They are important components of cable
modems and television connections as well as Ethernet connections (that is, LAN
and WAN).
In broadcasting networks
Modern
broadcasting networks (radio and television) largely rely on aluminium wire
(CCAW) for information broadcast. Basically, two forms of radio networks are
known- the first form is used for broadcasting and updates, advertising and
marketing whereas the other form is the backbone of police and armed forces
(used for communicating with each other). Television broadcasting involves
transmitting signals through cable and satellite television.
In submarine communications
Aluminium
wires clad with copper provide a great means of submarine communication and are
installed below the floor of the ocean to expedite the process of information
transfer across the globe.
In medical field
Aluminium wire finds also its use
in medical science instruments that are involved in diagnostic processes such
as medical ultrasonography.
