The flame-retardant cable is a cable whose sample is burned under the specified test conditions. After the test fire source is removed, the flame spreads only within a limited range. The residual flame or residual light can self-extinguish within a limited time. The fundamental characteristic is that in the event of a fire, it may be burned out and cannot be operated, but it can prevent the spread of fire.
