  • Reduced insulation wall thickness, thus space-saving installation
  • Copper screening complies with EMC requirements and protects against electromagnetic interference
  • Resistant to mechanical influences in harsh environmental conditions
  • Extended temperature range
  • Reduced flame spreading increases the protection against damage to persons and property in the event of a fire

Application range

  • In EMC-sensitive environments
  • For use in railway vehicles, for fixed and protected installation and applications where limited movement may occur
  • Suitable for control and monitoring circuits as well as locking circuits and internal wiring of equipment in trains and locomotives
  • Also applicable within oily environments and areas with increased ambient temperature
