Copper is now a
necessary metal that is utilised in both home and commercial electrical wiring.
Today, copper is used in many different applications, including
telecommunications, home appliances, and electronic circuitry.
According to estimates,
electrical copper wire and cable conductors are made using around half of the
copper that is mined.
Copper is a versatile
metal of the future because copper manufacturers already offer a variety of
copper wire products that may be utilised in a variety of electrical and
thermal applications. The excellent physical and chemical characteristics of
copper make it a popular conductor in many electrical and heating applications.
Look at these, shall we:
1. Both thermal and
electrical conductivity: The best non-precious metal for electrical and thermal
conductivity is copper. Copper wire has less resistance to electrical and
thermal conduction than aluminium, making it the material of choice for high
conductivity applications like lightning rods used to protect structures and
skyscrapers.
2. Malleable and
ductile: Due to its high ductility, copper may be pulled into a variety of
shapes, including cable
wires, strips, strands, and others. Due to its adaptability, copper
wire is used in both home and industrial settings where there are significant
electrical load transfers.
Due to its capacity to assume various shapes,
it is often utilised as the central component in numerous appliances.
3. Excellent tensile
strength: Copper has good tensile strength and can withstand a variety of
mechanical failures, including necking or neck-down, stretching, breakage, etc.
It is one of the explanations for why copper is chosen over aluminium.
4. Resilience to creep:
The deformation that results from a metal's expansion and contraction under
specific cyclic load conditions is known as creep. Compared to its counterpart,
aluminium, copper has a very low creep.
According to research that has been published,
aluminium has a considerable creep rate of 0.022% every 1000 hours at a tension
of 26 N/mm2 at a temperature of 200C. Copper has 0.022 per cent of this
difference, but the temperature needs to be at least 1500C. A screw can distort
a conductor and lessen contact pressure when the creep rate is higher. Joint
resistance, overheating, oxidations, loose connections, etc. result from this.
The ideal metal to use in a copper wire is copper because it has a low creep
rate.
5. Corrosion Protection:
In addition to its other mechanical qualities, copper possesses exceptional
corrosion resistance, making it one of the ideal metals for use in electrical
transmissions. It can be used in wires, pipes, and even radiators because it
has a low reactivity series and does not corrode.
6. Reduced thermal
expansion coefficient: Copper wire expands at a modest rate over a long period
as an electrical conductor. This is because it has a greater capacity for heat
dissipation than other metals, making it suitable for use in a variety of
applications involving heat dissipation, such as pressured connections and
joints, which reduce hot spots in electrical systems.
7. Solderability and
installation simplicity: Copper wires can be connected simply by soldering. For
transmission and termination locations, it can facilitate electrical
connections. Copper wires can be pulled through a variety of spaces, including
small crevices, to lay conduits because of their strength.
The various kinds of
copper wires are listed below. Manufacturers of copper wire divide their
products into the following groups based on the purposes for which they are
used:
1. Solid copper wire:
Electricity can be transferred using a single copper wire that is bare or
encased and covered with an insulating material. A soil copper wire of this
kind is typically used in home applications.
2. Stranded wire: A
copper-stranded wire is made up of multiple thin copper wires that have been
wrapped together. Because of its strong electrical conductivity, it is
frequently employed in industrial settings where electrical loads
fluctuate.
3. Cables: A copper
cable is created when copper wires are twisted, braided, woven, or twisted into
a single assembly. Tin is used as a coating agent to plate these copper wires,
which helps to decrease oxidation and extend the life of control
cables like these, which are utilised in industrial applications and
electrical appliances.
