Insulation
is nothing but a nonconductive material offering a high level of
resistance to the flow of electric current. Insulation prevents
electrical leakage prevents current of the wire from getting in
touch with other conductors and upholds the material integrity
of the wire by safeguarding against climatic and environmental
threats like water and heat.
It would not
be an exaggeration to say that the safety and effectiveness of the
wire to a large extent depends upon its quality of insulation.
The
insulating materials which are often utilized to cover copper and
other electrical wires and conductors fall into the following major
classes:
- Thermoplastic &
- Thermoset.
Some of the commonly used thermoplastic insulations
used nowadays:
- PVC (Polyvinyl Chloride)
- PE (Polyethylene)
- ECTFE
- PVDF
- Nylon
Some thermoset insulations often used are:
- XLPE
- CPE
- EPR
Insulation
on electrical wires is marked by a large number of codes and
numbering methodologies that indicate the type of wire and
performance as well as durability of the characteristics of the
insulation.
In the same
way, nonmetallic (NM) cables, that have multiple wires, contain
markings on the cable’s outer sheathing. Getting deeper into the
basics of markings helps buyers select the right kind of wire or
cable to serve your purpose.
Individually insulated wires are utilized for
installation inside of conduit or flexible metal cable. Here also,
the unique coding system relates to the performance-related
attributes of the wire insulation.
The commonest kinds of wire utilized in residential
construction includes THHN and THWN which are abbreviations of:
- T: Thermoplastic, a high quality heat-resistant plastic heavily utilized on different types of wire
- H: Heat-resistant up to 167 degrees F
- HH: Heat-resistant up to 194 degrees F
- W: Moisture-resistant; suitable for damp and wet environments
- N: Nylon-coated to resist damage from oil and gasoline
