3. Introduction
Electrical wiring is the building wiring and associated
devices such as switches, meters and light fittings used
in buildings or other structures. Electrical wiring uses
insulated conductors.

4.  VIR Wire-Vulcanized Indian Rubber Wire.
 CTS or TRS Wire-Cab tire Sheath or Tough
Rubber Sheath Wire.
 PVC Wire-Poly vinyl Chloride Wire.

5. 1) Vulcanized India Rubber (VIR).
 It is used in a wire as an insulator.
 Cotton tape and cotton braiding.
 To protect against corrosion.
 Tinned copper/ aluminium.
 Suitable for low and medium voltage supply only.

6. 2) Cable Tyre Sheath Wire (CTS).
 It is used in a wire as an insulator.
 It consist of Thicker Rubber/ Plastic, Tinned Copper.
 Don’t absorb moisture
 Available in 250/440V Only.

7. 3) PVC Wire.
 PVC(Polyvinyl chloride) is used in a wire as an
insulator.
 Widely used, long life, Durable against water, Heat,
Oil, UV light.
 Available in 600, 660, 1100Voltage.

8.  Coaxial cable – used for radio frequency signals, for example
in cable television distribution systems.
 Communications cable - These cables are used in a wide
variety of applications, including recording studios, data
transmission, radio transmitters, electronic circuits.

9.  Direct-buried cable - Direct-buried cable (DBC) is a kind of
communications or transmissions cable which is especially
designed to be buried under the ground without any kind of
extra covering, sheathing, or piping to protect it. Most direct-
buried cable is built to specific tolerances to heat, moisture,
conductivity, and soil acidity.

10. Flexible cables - Flexible cables, or 'continuous-flex' cables,
are cables specially designed to cope with the tight bending radii
and physical stress associated with moving applications, such as
inside cable carriers.

11. oNon-metallic sheathed cable - It is a type of covered
electrical cable consisting of at least two insulated
conductors and one bare conductor used in residential
wiring.
oMulticore cable - Multicore cable is a generic term for an
electrical cable that has multiple cores made of copper wire.

12.  Paired cable – Composed of two individually insulated
conductors that are usually used in DC or low-frequency AC
applications.
 Portable cord – Flexible cable for AC power in portable
applications.

13. Ribbon cable – Useful when many wires are required. This type of
cable can easily flex, and It is designed to handle low-level
voltages.

14. oShielded cable – Used for sensitive electronic circuits or to
provide protection in high-voltage applications.

15. oSubmersible cable - Tough & Flexible submersible pump cables
specially designed to supply power to submersible borehole
pumps in a deep borewell.

16.  Twin axial cable - Twin axial cabling, or "Twinax", is a type of
cable similar to coaxial cable, but with two inner conductors
instead of one.

17. Twin-lead – This type of cable is a flat two-wire line. It is
commonly called a 300 Ω line because the line has an impedance
of 300 Ω. It is often used as a transmission line between an
antenna and a receiver (e.g., TV and radio). These cables are
stranded to lower skin effects.

19.  Domestic Wiring:-
The electric power line enters our house through three wires namely
the livewire, the neutral wire and the earth wire. The red is the live
wire, the black is the neutral and the earth wire is given the green
plastic insulation.
