Title: How Modern Insulators make Copper Wires Safe and Effective


1
How Modern Insulators make Copper Wires Safe and
Effective?
2
Stranded copper wires are used in almost all
electrical appliances. Be it the tiny capacitors
or the mega-sized power transformers, they
feature in the industrial machinery owing to
their large-scale availability, easy machining
properties and above all, their process-friendly
characteristics. However, not all copper wires
are compatible with the insulators. Insulation of
electrical appliances is an important aspect.
3
Copper wires are excellent conductors. They have
low resistivity and hence used exclusively as
electric wires and grounding wires. However, in
some cases, the copper wire circuit require
insulation from each other. Lack of proper
insulation can lead to short circuiting,
resulting in fire.
Insulators in copper wire appliances use
primarily two types of materials. - Electrical
insulators - Dielectrics Dielectrics are
specialized materials that dont allow the
electric charge to flow through them. A dialectic
material is placed between two stranded copper
wire conductors to avoid passage of electricity
between them.
4
In modern industrial applications, traditional
insulator materials are used with good effect.
They are wrapped pre coated around the stranded/
braided copper wires for best results. Here are
top insulating materials used on copper wires and
rods.
- Ceramic Clay-based or porcelain glass
materials offer extensive insulation to the
copper wires. They typically feature in stranded
wires used in high voltage transmission cables
and underground wires. RF insulators also use
ceramic coated stranded copper wires. -
Plastics The family of plastic-based insulators
is growing long and effective. Chlorine and
fluorine based polymers are used in flexible
copper wires. PVC and PUC insulation on stranded
copper wires have largely replaced the rubber
coatings. Plastics are cheap and recyclable,
making them the top insulator material for
braided and stranded copper wires. - Teflon
This is another very effective solid insulating
material used with copper and aluminium wires,
largely featuring in aeronautics and automotive
parts. It is more durable and abrasion-resistant
than other insulators. Thanks to its high thermal
resistivity, the Teflon-coated copper wires can
withstand fire more effectively.

  • Other popular solid insulators used with copper
    wires are PFA and FEP foams and silica gel that
    solidify once wrapped around the copper
    conductors.
  • In recent times, glass too has made it big in the
    league of best solid insulators compatible with
    the copper wires.
  • When it comes to using fluid and gaseous
    insulators around copper wires, they prove to be
    a costly affair.
  • Switchgears use gas-insulted technology wherever
    high voltage transmissions are involved.
  • Petroleum oil, also called Transformer Oil is
    used in large sized transformers to dissipate
    heat away from the coils.
  • Capacitors used in aeronautics also use
    Transformer Oil as it serves the dual purpose of
    a coolant/ heat dissipater and an effective
    insulator around switchgears, landing gear
    circuits and bearings.

6
Things to note before choosing an insulator for
stranded copper wires - Cost effectiveness/
shelf life - Stiffening/ brittleness arising
due to insulation - UV light/ Ultrasonic and
Cold temperature resistance
These factors affect the performance of insulated
stranded copper wires in the long run.
