Cable structure

Bare copper conductor, to
DIN VDE 0295 cl.5, fine wire,
BS 6360 cl.5, IEC 60228 cl.5
Core insulation of special polyethylene (PE)
Core identification black cores with
imprint U1, V1, W3
GN-YE conductor (divided into 3)
Cores stranded in layers
1. Screen of semi-conductive fleece
2. Aluminium-coated polyester film
3. Tinned copper braided screen,
coverage approx. 80%
Outer sheath of PUR
Sheath colour: orange (RAL 2003)
acc. to DESINA®
With meter marking

Properties

PUR outer sheath: low adhesion, flame
retardant, extremely abrasion resistant,
halogen-free, resistant to UV, oil, hydrolysis
and microbial attack
This screened motor power supply cable,
with low mutual capacitance because of
the special PE core insulation, enables
low-loss transmission of power compared
to PVC-sheathed power supply cables
The optimal triple screening enables
interference-free operation of frequency
converters
Optimum compliance with requirements
for electromagnetic compatibility (EMC)
due to the triple screening
The materials used during manufacturing
are cadmium-free, contain no silicone
and are free from substances harmful
to the wetting properties of lacquers

Special features
Here the earth core cross section is divided
into thirds, which lie in the interstices
between the power supply cores. Due to this
symmetrical construction, the PE insulation
and the triple screening, very low capacitance
and inductance are achieved. EMC
compatibility is considerably enhanced.

Tests

PUR outer sheath
self-extinguishing and flame retardant
acc. to DIN VDE 0482-332-1-2 /
DIN EN 60332-1-2 / IEC 60332-1-2

Note

All cables are also available in JB with
coloured cores acc. to DIN VDE 0295
**) The current carrying capacity for
permanent operation at ambient temperature
of 30°C. For deviating ambient temperatures
the conversion factors should be used and
for further see the indication in
DIN VDE 0298-4.
AWG sizes are approximate equivalent
values. The actual cross section is in mm².

Application

This TOPFLEX^® MOTOR EMV 3/3 two-approvals, triple-screened 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 centres, industrial robots, transfer lines, handling equipment, etc. By dividing the earth core into thirds and dividing it evenly in the interstices between the power supply cores, a symmetrical structure has been achieved. This results in improved EMC, capacitance and inductance compared to the 4-core version.
EMC = Electromagnetic compatibility
To optimize the EMC features we recommend a large round contact of the copper braiding on both ends.
CE = Product conforms with Low-Voltage Directive 2014/35/EU.
