TX^® (C) 331 - 150/250 (300) V

Application

TX^® (C) 331  150/250 V fire resistant overall 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 provide a medium protection aganist external electromagnetic 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:
   Bare copper
   Stranded class 2
    
2. Insulation: 
   Mica tape + XLPE (cross-linked polyethylene)
   Optional: Special fire resistant HF 90 (halogen-free compound)
   with INFIT^TM technology
3. Collective screen:
   Alu/polyester tape with a tinned copper drain wire
    
4. Outer sheath:
   Polyolefin SHF1 (SHF2 on request)
