Mining Cable Flame Resistant Apparatus MT386, MT 818

 Introduction: 

In the past 20 years of practice, coal mine cables have experienced an innovation from non-flame retardant to flame retardant, especially in the test methods and determination rules for the flame retardancy of coal mine flame retardant cables (MT 818-2009, MT 386- 2011), the flame retardant performance of coal mine cables has been effectively controlled and improved.

The mining cable flame resistant apparatus is manufactured according to the standard MT 386-1995 "Test Methods and Determination Rules for the Flame Retardancy of Coal Mine Flame Retardant Cables" and is used to test the combustion of MT 818-2009 "Coal Mine Cables" under overload conditions. Designed and manufactured based on characteristics. The outer shell of the test chamber is made of stainless steel plate, with beautiful color and high fastness. The upper and lower structure of the test chamber and electrical control system facilitates operation.

It is suitable for flame retardant testing of coal mine flame retardant cables, flame retardant cable joints and other flame retardant tests. Under high current operating conditions, when the cable core reaches 204°C, a flame of a certain intensity and a certain period of time is applied to the cable to determine the quality of the cable sheath and The equipment is developed based on the flame retardancy and high temperature resistance of the insulation material in this state.
