Power transformer SG-250k

isolationdryfor mining equipment

Product Overview: The three-phase dry-type transformer for coal mine harvesters powers underground equipment. It's explosion-proof and efficient, ensuring stable ops in hazardous mines and facilitating mining. Specific Introduction: 1.High Efficiency: Over 99% efficiency. Advanced copper wire winding and core design cut energy losses, stably outputting proper voltage, saving energy for harvester's long use. 2.Strong Protection: Class H insulation and three-proofing (waterproof, dustproof, anti-corrosion). The explosion-proof shell and sealed structure prevent explosion risks, protecting personnel and equipment. 3.Compact & Efficient Structure: Copper wire winding makes it compact. Full copper plate for heat conduction and water cooling system ensure good heat dissipation. Flatness ≤ 1.6μm for smooth ops and fitting complex underground layout. 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.
