Prod. Overview: Vacuum-sintered transformers shine in low-volt., high-current apps., supporting stable power system operation. Details: 1.High permeability: Speeds up magnetic flux response, reduces excitation current, improves transformer efficiency and performance stability under low-volt., high-current conditions. 2.Foil winding benefit: Reduces leakage and eddy current losses, improves voltage waveform, enhances current-carrying capacity and overall performance in high-current scenarios. 3.Heat dissipation control: Reasonable heat sink and duct layout with good thermal conductivity quickly dissipates heat, controls temp. rise, reduces high-temp. impacts on insulation and electrical performance. 4.Insulation protection: Vacuum pressure impregnation creates a solid insulation layer, and dust-proof housing blocks dust, providing dual protection for insulation in complex env. 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.
