  • Wide application range due to multiple certifications
  • Cost-saving, easy installation due to omission of closed raceways (suitable for open wiring)
  • Overall braid minimises electrical
  • Decoupling of circuits by means of
    twisted-pair (TP) design (crosstalk effects)

Application range

  • Control and signal cables for internal and external wiring
  • For the North American market
  • On the basis of CMG, PLTC or ITC direct laying on cable tray in the USA, in conjunction with -ER (Exposed Run) for unprotected transition sections with a length of not more than 6 ft. each
  • Thanks to the DIRECT BURIAL approval, direct burial of versions with the nominal conductor cross-section 18 AWG in the USA
  • Torsion resistant up to ±150 °/m for the drip loop of wind turbine generators

Product features

  • Oil-resistant according to UL OIL RES I
