Cable structure
  • Bare copper conductor, fine wire with
    AWG dimensions
  • Core insualtion of special PVC
    with clear nylon coating
  • Core identification black cores with
    continuous white numbering
  • GN-YE conductor (divided into 3)
  • Cores stranded in concentric layers
  • 3 power + 3 ground conductor design
  • 1. Screen with special aluminium film
    2. Tinned copper braided screen,
    coverage approx. 80%
  • Outer sheath of special TPE
  • Sheath colour: black (RAL 9005)
  • With length marking in feet
  • Resistant to oil and sunlight
  • Due the optimal screening an
    interference-free operation of
    frequency container is obtained
  • The materials used during manufacturing
    are cadmium-free, contain no silicone
    and are free from substances harmful
    to the wetting properties of lacquers
  • Behavior in fire acc. to CIC FT4
  • UL
    UL Type TC-ER, UL 83, 1277, 2277,
    WTTC, Oil Res I, NFPA 2012
  • CSA
    c(UL) Type CIC FT4, CSA C22.2 No. 230,
    CSA C22.2 No. 239
  • VFD = Variable Frequency Drive
It is used as a power supply cable under average mechanical stress for fixed installation and sometimes for free movement in dry, moist wet rooms and outside. It is used in the automotive industry, food processing industry, transfer streets, packaging industry, machine tools, handling equipment, other industrial uses include pumps, fans, transport belts and in air conditioning systems, etc. Used in explosion proof areas.
EMC = Electromagnetic compatibility
The screen must be connected at both ends and ensure large-area contact over the entire cable circumference for compliance with the functional interference requirements of EN 55011.
CE = Product conforms with Low-Voltage Directive 2014/35/EU.
