Product Overview: As a rail transit power mainstay, this transformer feeds frequency converters. It's crucial for train electrical gear and signal system, ensuring rail transit's efficient, reliable service. Specific Introduction: 1.Vacuum Impregnation Shield: The vacuum process erects a solid insulation barricade. Given rail's special environment, it resists harsh erosion, preserves insulation integrity under intense vibration, stops leakage and short circuits, ensures electrical safety, and safeguards system stability. 2.Heat Dissipation & Stable Run: The ace heat dissipation mechanism dissipates heat well in rail's vibration and controls temperature rise. The low temperature rise preserves insulation performance, cuts failure odds. With flame-retardant and three-proof treatment, it runs stably in complex settings and slashes maintenance costs. 3.Low Magnetic Leakage & Adaptability: Low magnetic leakage design trims interference to surrounding equipment, boosting system compatibility. It has three-proof and flame-retardant materials, works in rail's humidity, dust, and heat. The PT100 eases temperature monitoring and ensures long-term reliable operation. 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.
