Abstract: Full scale experimental study on combustion characteristics of FEP communication cable was carried out by using FIPEC test device. The flame spread of communication cable was studied by testing the parameters of heat release rate, smoke production rate, combustion growth rate index and flame spread distance in the combustion process. Meanwhile, the factors influencing the flame spread of communication cable were analyzed. It is found that the power of ignition source has little effect on flame spread of FEP communication cable; The arrangement of cables and thermal boundary conditions are important factors affecting flame spread of FEP communication cables. Under the same fire power, the flame spread speed of cable spacing arrangement is faster than that of contact arrangement, and the fire risk is greater; The flame spread speed and fire risk of the steel ladder with non-combustible back plate ar much faster than those without back plate; The combustion performance of FEP communication cable can reach B1 level of GB 31247- 2014 Classification of Combustion Performance of Cables and Optical Cables.
Key words: communication cable, combustion performance, heat release, smoke production
