Abstract
The analysis and review of the thermal decomposition properties required for the fire spread simulation of cables composed of multiple materials were performed. Thus, a typical two-step pyrolysis reaction was identified independent of cable type. It is expected that the Kissinger and flynn–wall–ozawa (FWO) methods, which are calculated using various heating rates, more accurately predict fire spread than the input method that uses the and values calculated using a single heating rate. Consequently, in the case of flame-retardant cables (CLASS 1E and TFR-8), the Kissinger method is more likely to overestimate the fire spread rate than the FWO method. In the case of polyvinyl chloride (PVC) cables (vinyl cabtire power cable, VCTF), the fire spread rate may be underestimated.
