Experimental Investigations on Combustion Behaviors of Live PVC Cables
This paper investigated the combustion behaviors of live PVC cables with overload currents experimentally.The smoke coefficient of released smoke and the released gas concentration were examined.The results indicate that the combustion of live PVC cables can be divided into four stages,i.e.,core exposed with a little smoke,obvious flame,maximum smoke and smoke depress.For most cases,using blue laser is better than using rad laser,since the extinction coefficient of the rad laser was larger than that of the blue laser.The response time of the detection of the released typical gases due to cable pyrolysis decreased and the peak values of the typical gases increased with the overload currents.In addition,the time to reach the peak value of gas concentration also decreased with the overload currents.
