RESIDUAL RISKS
Here is a list of residual risks in the event of incorrect transport,
installation, use or maintenance of Mineral Insulated Cable
(MICO
®
) and their Terminations.
-
Electrocution
due to incorrect execution of the
termination, putting one of the phases on the earth
sheath.
-
Electrocution
or insulation loss due to
incorrect handling or installation because of
shock, crushing, perforations or excessive bending of the
cable, that could damage the earth sheath.
-
Bump
due to the cable fall in case of faulty
handling or installation.
-
Cutting / Shearing / Puncture / Burns
during manual operations required for
the installation and the termination's execution.
-
Generic hazard
for transportation, installation, use or
maintenance performed by unqualified and non
trained or incorrectly equipped personnel.
-
Contact with
chemicals
.

ATTENTIONS TO FOLLOW
The following are the attentions to follow during transport,
installation, operation and maintenance of Mineral Insulated
Cable (MICO
®
) and their Terminations.
-
Always wear PPE required for
transportation, installation and
use (gloves, goggles, helmets,
shoes).
-
Designate for these operations only technical personnel
trained on the correct procedures for the transport,
installation, use and maintenance of Mineral Insulated Cable
(MICO
®
) and their Terminations.
-
During the execution of the termination connect immediately
the earth sheath to a properly marked section of cable,
before performing the remaining steps.
-
Pay attention to the weight to transport and handle, and
certainly if more than 20 kg, do not carry it manually but use
suitable lifting and transport equipment.
-
During installation and execution of terminations always
mark in a visible and unequivocal way the cables at both
ends.
-
At the end of installation and execution of terminations make
a visual check on the earth sheath, to check for any
discontinuities, perforations, excessive crushing or bending.
-
At the end of installation and execution of terminations
perform a strength test and an insulation resistance test
before powering up the system.
-
Use only KME tools for installation and execution of
terminations.
-
Use only KME terminations and accessories.
-
When you install at altitude, constrain the cables through the
use of KME staples, using an adequate fixing distance.
-
Durante il trasporto, l’installazione e lo stoccaggio prestare
attenzione in ogni momento al raggio di curvatura del cavo,
che deve essere appropriato al diametro del cavo affinché lo
stesso non venga danneggiato.
-
During transport, installation and storing avoid shocks,
crushing or perforations that may make the cable unusable.
-
The mineral insulated cable is moisture sensitive, because
the magnesium oxide, that acts as insulation, absorbs
moisture if left exposed, causing the decrease of the
insulation resistance value. If stored for a long time or if it’s
necessary to hold the cable exposed to humid environment,
it is good practice to temporarily seal the ends by wrapping
them with self agglomerating tape or by wrapping the ends of
the cable with common insulating tape.
-
In case of storage, even temporarily, use covered areas,
protected from weather and far from transit zones; also the
plastic cover of the coated cables may harden and
deteriorate if kept to sunlight for a long time.
-
In case of manipulation of chemical agents, follow the
instructions of the related material safety data sheet (MSDS).
-
Before uninstall the cable, ensure that there is no voltage in
the system.

INSTALLATION
For the correct and complete installation procedure and
execution of the terminations procedure carefully follow what
reported extensively in the full document “
Instructions -
Mineral Insulated Cable (MICO
®
) and their Terminations
”
available in full on the website
www.kme.com
or by e-mail at
. This document shows all KME accessories
required
and
detailed
procedures
to
fully
execute
transportation, installation and termination of Mineral Insulated
Cable (MICO
®
), accompanied by technical data, tips and
detailed illustrations about.
-
The mineral insulated cable is normally supplied in a self-
supporting coil having an inner diameter of 500, 1200 and
1450 mm, depending on the outer diameter of the cable. To
properly carry out the coils is possible to build a simple
unwinder, using a metal profile or of wooden boards such as
used for the support of common cables.
-
Before fixing, the cable it must be straightened by hand or by
using a straightener or a tube bender; the final straightening
can be performed using a block of wood and a hammer, or
with a rubber hammer; a metal hammer should never be
used directly on the cable sheath to avoid compromising the
mechanical and electrical characteristics of the sheath.
-
When the temperature of the sheath of a cable MICO
®
,
taking account of the ambient temperature and the increase
in temperature due to the current, does not exceed 70°C,
one can choose between the bare cable and the cable
coated in LSF; for temperatures of the sheath more than
105°C, one must choose the bare wire; for continuous
