  • Symmetrical cable design increases the EMC and significantly reduces leakage and motor bearing currents, interference on data transmission as well as corrosion on building structures
  • Low capacitance bundle design with counterrotating protective conductor enables longer cable connection between frequency converter and motor and significantly simplyfies the cable connection
  • Copper braiding screens the cable against
    electromagnetic interference
  • Allows much faster speed and accelerations which increases the economic efficiency of the machines
  • Resistant to contact with many mineral oil-based lubricants, diluted acids, aqueous alkaline solutions and other chemical media
  • Wide temperature range for applications in harsh climatic environments

Application range

  • Connecting cable between frequency converter and motor
  • In power chains or moving machine parts
  • For use in assembling & pick-and-place machinery
  • Particularly in wet areas of machine tools and transfer lines
