Fire Resistant Network Cable
Fire Resistant Network Cable is the most commonly used twisted-pair cable flame retardant grade, its test standard is UL 1581.
So the CM level cable fire characteristic is as follows: not spontaneous combustion; In the flame will smoke, and may appear flame; The speed of flame spread along the cable is very slow; When the external fire source is cut off, the fire on the cable will gradually go out.
CM class cables do not take into account smoke density and toxicity (no mention of smoke density and toxicity in UL 1581) as long as they meet flame retardant rating requirements.Cm-level cables are mostly horizontal twisted-pair and are used in wiring subsystems.The sheath layer of CM class cable is mostly PVC material, while the insulation layer is high-density PE material.The advantage is that it is cheap, while the disadvantage is that the ignition point is low, the normal operating temperature is below 70℃, when the temperature reaches 160℃ or higher, THE PVC material will emit toxic halogen and smoke.
If you burn it, you release a lot of heat.According to the code of construction for integrated wiring, twisted pair wires shall be laid through metal pipes and behind metal Bridges in floors, ceilings and walls.In this case, the use of ordinary twisted-pair wire can be installed in any situation without concern for smoke and toxicity.
