Maintenance
Cleaning
Insulation
Most
of
the
plastics
and
synthetics
used
in
insulation
systems
are
attacked
by
solvents
containing
aromatics
or
halogenated hydrocarbons
.
The
use
of
these
may
cause
crazing
and
deformation of
the material
reducing
the dielectric
strength
.
Isopropyl
alcohol is
the
only
recommended solvent cleaner
.
A
DANGER
The
use
of
unauthorized
parts
in
the
repair
of
the

tampering by
unqualified
personnel
will
result
in
dangerous
conditions
which
will
cause
