Application
This MOTORFLEX 3/3 two-approvals,
triple-shielded motor power supply
cable for frequency converters
provides outstanding EMC in machines
and systems.
Suitable as a supply and connecting
cable for high mechanical stresses,
in Fixed Installations and occasional
free movements in dry, moist
and wet environments, as well
as outdoors.
Areas of application include
machine tools, processing and manufacturing
machinery, machining centers, industrial
robots, transfer lines, handling
equipment, etc.By dividing the
grounding conductor into thirds and
dividing it evenly in the interstices
between the power supply conductors,
a symmetrical Construction has been
achieved. This results in improved
EMI, capacitance and inductance
compared to the 4 conductor version. EMC =
Electromagnetic Interference
To optimize the EMI features we recommend a large round contact of the copper
braiding on both ends.
=
The product is conformed with the EC Low-Voltage Directive 2006/95/EG.
Properties
PUR outer jacket: low adhesion, flame
retardant, extremely abrasion resistant,
halogen-free, resistant to UV, oil, hydrolysis
and microbial attack
PUR jacket: self-extinguishing and
flame retardant, test method B acc. to
DIN VDE 0472 part 804 and IEC 60332-1
This shielded motor power supply cable,
with low mutual capacitance because of
the special PE conductor insulation, enables
low-loss transmission of power compared
to PVC-outer jacket power supply cables
The optimal triple shielding enables
interference-free operation of frequency
converters
Optimum compliance with requirements
for electromagnetic interference (EMI)
due to the triple shielding
Tests
Low mutual capacitance: tested acc.
to DIN VDE 0472 part 504, test method
B
Special features:
Here the grounding
cross-section is divided into thirds,
which lie in the interstices between
the power supply conductors. Due to this
symmetrical construction, the PE insulation
and the triple shielding, very low
capacitance and inductance are achieved.
EMI compatibility is considerably enhanced.
