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.
