摘要： 利用FIPEC 试验装置对FEP 通信电缆的燃烧特性进行了全尺寸试验研究。通过测试通信电缆在燃烧过程中的热释放速率、产烟速率、燃烧增长速率指数及火焰蔓延距离等参数研究其火焰蔓延情况，同时对影响电缆火焰蔓延的因素进行了分析。研究发现：点火源功率对FEP 通信电缆的火焰蔓延影响较小；电缆的排列方式和热边界条件是其影响FEP 通信电缆火焰蔓延的重要因素。同火源功率下，间隔排列比接触排列的火焰蔓延速度更快，其火灾危险性要大；同火源功率下，在钢梯后增加不燃背板比未加背板安装的火焰蔓延速度要快的多，其火灾危险性要大得多；FEP 通信电缆燃烧性能可达到GB 31247-2014《电缆及光缆燃烧性能分级》的B1 级。

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.
