Coal Mine Cable Load Combustion Tester, MT818

This device is designed and manufactured in accordance with the corresponding requirements of the MT818-2009 coal industry standard, and is suitable for flame-retardant tests of flame-retardant cables and flame-retardant cable joints used in coal mines. Under the condition of high current operation, when the cable core reaches 205°C, apply a certain intensity of flame to the cable for a certain period of time to determine the flame retardancy and high temperature resistance of the cable sheath and insulation materials in this state.
