2. Introduction
A large proportion of the electrical signals are transmitted
through solid electric conductors. Such electrical signal
carring conductors take the form of wire or cable. A wire
is a single conductor. A cable is configuration of insulated
wire bounded together. A large signal power wire is also
called a cable.
The better the electric conductor, the lower will be the
resistance. Thus very low resistance losses will occur
during the transmission of electrical signals.
So, the conductors in the wire and cables are made up of
copper and aluminium.
3. There are Mainly five Types of
Wiring;
1.Wooden Casing and Capping Wiring
2.CTS(Cabtyre Sheathed Wiring)
3.Cleat Wiring
4.Lead Sheathed Wiring
5.Conduct Wiring
4. 1. Wooden Casing and Capping
wiring
Such wiring is carried out in grooves of wooden casing.
The casing is made of season teak wood and is used in
rectangular blocks having a number of grooves equal to
the number of wires. After the Conductors are fixed in the
grooves of casing, they are covered in teak wood capping
of rectangular blocks having the same width as that of the
casing.
Such type of wiring is used for voltage for 250V. It is
nessery to safeguard it against dampness and risk of fire.
Such type of wiring is inexpensive and easy to install and
repair. However the appearance that is gives is very
shabby.
6. 2. CTS(Cabtyre Sheathed Wire)
Such a type of wiring is used in resident used
cabtyre sheathed wire as the conductor. These
wire runs in teak wood battens which in turns are
fixed on the walls or ceilings by mean of screws
and wooden plugs.
Such wire are not much affected by chemicals and
steam. They have a better appearance compared
to the wooden capping and wiring. Also they have
a longer life with less risk of fire.
8. 3. Cleat Wiring
Such type of wiring is used for temporary
connections. E.g., for functions, marriages etc.
Here Vulcanized Indian Rubber(VIR) or Polyvinyl
chloride(PVC) insulated wire is used as a
conductors. These wire are run on the walls and
ceiling with the help of porcelain cleats. These
are grooves provided on the cleat base to
accommodate the wire. Once the wire are run
into the cleat base, the cap of the cleat is placed
over it.

10. 4. Lead Sheathed Wire
The conductor used here are insulated with
Vulcanized Indian Rubber. Then, an outer shed
made of lead- aluminium alloy containing 95%
lead and 5% aluminium is used to cover the
insulated conductor. This sheet protects the
wiring from mechanical injury, atmosphere action
and dampness.
The overall cost of the cable is very high. It is
used only in low voltage installations.
12. 5. Conduit Wiring
The Conductors used here are insulated with polyvinyl
chloride or vulcanized Indian rubber. They are then
carried in middle steel tubes commonly called conduits.
These conduits are then installed on the wall’s surfaced or
concealed in the wall or ceilings. They are concealed
inside the plaster of the walls and hence the appearance
of the house or the building remains unaffected.
Such a type of wiring is considered best for domestic and
commercial installation. It provides protections against
fire hazards, mechanical damage, dampness and shocks.
This type of installation has a long life. It is costliest
wiring system.
