[0002] Plastics used for insulation and sheathing of wires and cables are commonly known as cable materials. During the cable production process, the cable needs to be passed through an extruder so that a layer of cable material is wrapped around the outside of the cable to ensure the service life and safety of the cable. Flame-retardant cable refers to a cable that, under specified test conditions, burns the sample. After the test fire source is removed, the spread of the flame is only within a limited range, and the residual flame or residual burning can extinguish itself within a limited time. Existing highly flame-retardant cable materials are usually tested in closed combustion boxes for combustion tests. In a closed environment, the fire source is easily extinguished due to lack of oxygen, resulting in errors in the test results. At the same time, the harmful gases generated by the combustion of cable materials are not treated and discharged, which can easily cause environmental pollution. [Contents of the utility model]
