is designed according to the standard MT 386-1995 "coal mine fire retardant cable test methods and determine the rules",and used to test the combustion characteristics of MT 818-2009 "cable for coal mine" under overload condition. Chamber shell made of stainless steel plate, beautiful color fastness. For flame retardant cable for coal mine, flame retardant cable joints and other flammability test under high current operation state, the cable core reached 204â, the cable applied certain intensity and time of the flame to determine cable sheath and insulating materials in this state of flame retardant materials, anti high temperature performance and other indicators.
2, Combustion chamber size is 1100Ã500Ã1000mm; The internal volume is more than 0.5mÂ³;
3, The electronic control box size of 1100Ã500Ã800mm;
4, The brass burner diameter of Â¢ 9.5 Â± 0.5mm, the length is about 102mm, with air adjusting hole;
5, With a torch lever, sliding the burner freely;
2, The flame height can be adjusted;
3, Needle valve can precisely control the gas flow and the flame height;
4, Regulating valve can precise control the gas pressure;
5, The torch can precisely controll flame height and burn calories;
Electrical control system:
2, Manual control the load breaking;
3, Test time reminder; reminds experimenter evacuating blowtorch when burned 1min.
4, The load current is 10 ~ 3000A.
5, The timer range: 0 ~ 9999s (standard 4min) when the temperature reaches 204 â, the system will alarm and automatic cut-off to extinguish the flame.
