TX® ( I ) 331 150/250V 1T1.5

Application

TX^® (I) 331  150/250 V fire resistant overall and individually screened twisted pair cables maintain circuit integrity in case of fire by meeting performances requirements from the IEC 60331 series for 90 minutes. These telecommunication and instrumentation cables show a strong protection aganist cross-talk and result into a good compromise between TX^® (C) 331 and TCX^® (C) 331 cables against external electromegnetic disturbances. Designed with halogen-free fire retardant materials, they provide optimum safety for people and maximal asset protection against all risks of fire.

Design

1.   Conductor:
      Stranded bare copper
      Class 2
2.   Insulation: Mica tape + XLPE (cross-linked polyethylene)
      Optional: Special fire resistant HF 90 (halogen-free compound)
      with INFIT^TM technology
3.   Individual screen:
