    • 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 in manufacture are cadmium-free and contain no silicone and 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 to DIN VDE 0482-332-1-2, DIN EN 60332-1-2, IEC 60332-1 (equivalent DIN VDE 0472 part 804 test method B)

    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 part 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 compatibillity
    • To optimize the EMC 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/EC.
