The big difference between fire-resistant cables and fire-resistant cables is that fire-resistant cables have an extra layer of mica than fire-resistant cables, while fire-resistant cables do not.
Fire-resistant cables mostly refer to flame-retardant cables. The main difference from fire-resistant cables is that fire-resistant cables can maintain normal power supply (use) for a period of time when a fire occurs, while flame-retardant cables do not have this feature.
Fire-resistant cable refers to the performance that the sample is burned in the flame under the specified test conditions and can still maintain normal operation within a certain period of time. The fundamental feature is that the cable can still maintain the normal operation of the line for a period of time under burning conditions. In layman's terms, in case of fire, the cable will not burn at once, and the circuit is relatively safe.
Flame retardant cable refers to: under the specified test conditions, the sample is burned, after the test fire source is removed, the spread of the flame is only within a limited range, and the residual flame or residual burn can be extinguished within a limited time. The fundamental characteristic is: in the event of fire, it may be burnt out and cannot operate, but it can prevent the spread of fire. In layman's terms, in the event of a fire in the cable, the combustion can be limited to a local area without spreading, and other equipment can be protected to avoid greater losses.
