TCX® ( I ) 331 7T0.75

Application

TCX^® (I) 331  150/250 V fire resistant armoured 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 provide strong protection aganist cross-talk in both low and high frequency runs, making them suitable for highly polluted electromagnetic surroundings. TCX^®(I) 331  cables are used for detection and warning systems where enhanced mechanical protection is required. Designed with halogen-free fire retardant materials, they provide optimum safety for people and maximal asset protection against all risks of fire.
