  • For protection against personal injury and damage to property.
  • Insulation integrity for up to 120 minutes under the effect of fire (classification PH120 according to EN 50200). Guarantees functional integrity and the power supply in the event of an emergency.
  • Compliant with standards for use in rail vehicles: fire safety and cable design requirements according to DIN EN 50264-3-2, type MMS; fire behaviour in accordance with DIN EN 45545-2, hazard level HL3.
  • The cross-linked insulation and sheath materials promote longevity at high temperatures or with a high current load, and provide high dielectric strength.
  • Ideal protection against electromagnetic interference due to copper shielding braid with high degree of coverage

Application range

  • For wiring safety-related components in railway vehicles.
  • Especially for environments where electromagnetic compatibility (EMC) is required.
  • Typical application areas are emergency power circuits for alarm, lighting and communication purposes, which must maintain their function for a certain period of time in the event of a fire.
  • For use in railway vehicles, for fixed installations and applications where limited movement may occur
  • Can be used in dry, damp and especially in harsh and oily environments.
