Underground environments feature high risk conditions including methane gas, explosive coal dust, high humidity, heavy dust and sustained mechanical shocks. Frequent start stop of digging, slewing and travelling movements brings drastic load fluctuations that readily generate inrush currents, harmonics and voltage spikes. Once electrical components produce electric arcs or over heat, major safety hazards of igniting gas and coal dust will emerge. As key supporting components of variable frequency electric control systems for excavators, explosion proof transformers and reactors for mining applications realize functions of voltage conversion, galvanic isolation, harmonic suppression, inrush current limiting and auxiliary electric leakage protection. Custom developed against Class I coal mine explosion proof standards and coal mine safety specifications, our products feature explosion proof enclosures, reinforced insulation, vibration resistance and moisture dust proof performance compared with general purpose industrial products. They resolve pain points including poor power quality, high electric arc risks and vibration induced early stage failure for underground mobile mining equipment and guarantee safe and reliable operation of mining excavators in high risk underground coal mine environments.<\/p>\n<p><a class=\"btn-more\"
