Product Overview: The rail transit transformer excels at steady converter power supply. It's a must in the rail electrical system, furnishing top-notch energy for train operation, control, and safety, promoting smooth rail transit. Specific Introduction: 1.Efficient Conversion Core: With high-perm. silicon steel sheets and advanced winding, it hits 95% efficiency. The sheets trim magnetic hysteresis loss, windings pare copper loss. When powering converters, it converts energy smartly, cuts heat, lifts utilization rate, suits long-term stable operation, and trims costs. 2.Tough Overload Traits: Its structure and materials endow excellent overload capacity. When rail transit equipment starts, accelerates, or overloads, it withstands large current shocks. Through internal regulation systems, it keeps output traits stable, ensuring key train systems have unfailing power and operation safety. 3.Vacuum Impregnation Efficacy: The vacuum process ensures high electrical isolation. In rail's vibration and complex EM environment, it blocks winding breakdown, sharpens anti-interference, ensures reliable power supply, and lessens external radiation, enhancing the system's EM environment quality. 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.
