Product Overview: The coal mine lighting transformer changes high voltage to safe one for underground use. It's key for mining safety and production. Specific Introduction: 1.High Efficiency & Low Rise: Good design makes it efficient. Low loss and rise. In mines, it stops insulation issues, runs well, saves energy, and gives stable light. 2.High Insul. (H): Fine stuff and work mean Class H. In bad mine conditions, no leakage or short, for long use and steady light. 3.Stable Output: Good regulator. Output is stable with grid changes. Light is even. Helps miners work safe and fast. Operation Environment A) Altitude: Not exceeding 1000m, shall be derating used if above 1000m; B) Ambient Temperature: -25℃~55℃. C) Relative Humidity: ≤95%; D) As to the installation site, to make sure no bad effect on transformer insulation, chemical deposition, dust, and other explosive or erosive medium. E) The supply voltage approximates sinusoidal wave, and the three-phase voltage is relatively balanced.
