Cables are made using braided
wires for two reasons mainly. The braids of conductors are helpful in screening
the electric charge persisting in a metallic cavity. Electrical appliances and
their parts don’t get affected by electrostatic forces generated by the flow of
current in a conductor. This phenomenon is known as electrostatic screening.
Braiding also provides mechanical strength to the conductor.
It also provides flexibility which is very important for metallic wires and
strips. A braided wire could easily be stretched or bent without taking the
risk of breaking or deforming it due to buckling and kinking permanently as in the
case of metal tapes. The special designing of interweaving and crossing the
wires allow all this to happen.
Braided wires are also used as a
protective covering for cables as they protect cables from many external
factors and unexpected accidents which may break the wire and cause serious
accidents. They protect wire against high-temperature surfaces, the wire is
safe from abrasions and cut that may occur. It also helps them to keep the
rodents away. Cable harnesses are also made by braiding wires to ensure cables
are grouped together.
How braided wires are made?
Firstly, copper metal is drawn
into thin wires. Each wire is taken individually and braided with other wires
in intricate patterns. Some of them are wrapped like spool at a very fast speed
in circular designs at the center of the cross-section.
This method is applied to
convolute the strands of wire together to form a braid that may be round. This
kind of wire is known as Braided-only copper wire. The braid may be beaten
later to turn it into a braided strip by using a press roller machine.
This braided copper strip is
durable and strong like its round counterpart. It has the advantage of offering
a wide surface area. Its resistance(R) is low and therefore, it has high
conductivity. This increases the efficiency of the machine.
Large voltage fluctuations are
easily handled by these types of copper wires. They are capable of withstanding
and avoiding any short-circuits due to these fluctuations. They are used in
making coaxial cables and enduring sophisticated electric circuits. They can
absorb shocks that may occur in underground wiring.
Braided copper strips are used in
radio equipment so that they may provide low resistance. Low resistance ensures
receiving of maximum bands of radio frequencies. They are extensively used in
commercial protection from lightning. These strips generate a minimal amount of
heat to avoid any disasters.
Braided copper strips are no less
than a boon for heavy engineering industries. Copper is full of surprises. It
has surprised our ancestors and it doesn’t fail to make us awestruck today. A
gift of nature to mankind!
