CABLES & OVERHEAD CONDUCTORS:
•
The
role
of
electricity
has
become
more
significant
in
today’s
society;
electricity
distribution
has
to
be
reliable
and
there
should
be
no
outages
.
Furthermore,
ageing
of
networks
is
an
issue
that
has
to
be
taken
into
account.
Underground
cabling
will
be
one
of
the
basic
elements
in
renovation
of
rural
area
overhead
(OH)
line
distribution
networks.
Cabling
improves
network
reliability
and
has
an
impact
on
the
outage
costs
;
as
a
result,
the
lifetime
costs
and
thereby
the
total
costs
of
the
network
are
reduced.
•
The
Cable
and
Overhead
Conductor
network
has
the
highest
impact
on
reliability
in
electricity
distribution
,
because
more
than
80 % of the customer-experienced outages
are caused by these Networks.
•
The
Overhead
Conductor
Networks
are
less
expensive
than
the
Underground
Cable
Networks,
but
is
more
exposed
to
faults
in
comparison with underground cable networks.
•
70%+
of
Underground
Cable
Networks
are
Copper
because
of
the
smaller
size
of
cables
required
as
in
comparison
with
aluminium
cables
for
the
same
current
capacity
requirements
and
also
copper
is
a
much
better
conductor
of
electricity
than
aluminium.
Unfortunately copper is also highly in demand amongst criminals.
Common faults on cable / overhead conductor networks causing power failures are:
1
.
3rd party interferences
(Criminals steal / vandalise Cables / Conductors)
2
.
People / Service Providers digging on cable trenches
damaging underground services
3
.
These
days
a
lot
of
other
services
are
also
installed
next
or
on
top
of
existing
services,
during
installation
existing
services
can be damaged.

.
Underground
cable
/
Overhead
Conductor
networks
are
more
than
often
overloaded
because
of
illegal
connections
and
uncontrolled
/
undetected
energy
consumption
which
damage
the
cables
and
prematurely
end
the
useful
lifespan
of
the
cable
/ overhead conductor.

.
Poorly installed
networks, especially underground cables
6
.
No preventative maintenance programs to detect early signs of pre-mature failures etc.

.
Natural Ageing of networks
8
.
Degradation
of
the
cable
sheath:
There
are
several
reasons
why
the
sheathing
material
may
degrade,
including
excessive
heat
or
cold,
chemicals,
weather
conditions,
and
abrasion
of
the
sheath.
All
of
these
factors
can
ultimately
cause
electrical
failure as the insulated cores are no longer protected by the sheathing as originally designed.
9
.
Heating
of
cable:
Excessive
heating
of
the
cable
will
cause
degradation
of
the
insulation
and
sheathing
material
and
premature
failure.
The
heat
may
come
from
an
external
source
or
may
be
generated
by
the
resistance
to
current
flow
in
the
conductor - a particular problem if the cable is overloaded and/or underrated for the application.

.
Electrical
Overloading:
Electrical
overloading
normally
occurs
when
the
cable
is
underrated
for
the
application
or
when
too
much load is being placed on the cable.

PROTECTION & MONITORING:

Our

Software
system
focus
on
Prevention,
it
is
our
goal
to
ensure
that
possible
damages
/
theft
etc.
to cables / overhead conductors and underground services are early detected before they actually occur.
