abstract="Polyvinyl chloride (PVC) is widely applied in cables as insulation materials, which  are vital for operation and control of industrial processes. However, PVC cables  fires frequently occur, arousing public concern. Therefore, experimental methods are  used to study flammability and flame-spread characteristics of PVC cable in this  paper. Influences of cable structure and number are investigated, which is scanty in  previous works. As cable core number of single cable or cable number of multiple  cables rises, average flame height and width increase while the increment decreases. Formulas concerning dimensionless flame height and single cable diameter (or total  width of multiple cables) are obtained. The former is negatively correlated with the  latter. For single cable, convective heat transfer is dominant, and flame-spread  rate decreases as cable core number increases. Cable maximum temperature, which  drops first and then rises as cable core number increases, is observed in the cable  core area. For multiple cable, the flame-spread rate increases as cable number  increases. As the cable number rises, the length of pyrolysis and combustion zone  increases while the maximum temperature of cable surface decreases. This work is  beneficial to fire hazard evaluation and safety design of PVC cables.<p /> <p>Language: en</p>",
