Fire-resistant cable and Flame retardant cable, as two different types of fire performance cables, they have an important distinction, even though they have different fire performance and their own classification.
Fire retardant cables are mainly stopped or protect the fire from further spread the cable explore to a fire, they are classified to A, B and C grade. The fire-resistant cable is mainly to keep the circuit integrity and for some time after the fire happened. That is to say, if the two kinds of cable are exposed to a fire same time, the fire retardant wire will not burn and spread the flame. The fire-resistant cable can continue to work for a period of time.
