Description: The 700A DC reactor is tailored for rail transit systems, including metro traction networks and high-speed rail power supplies, integrating VPI (Vacuum Pressure Impregnation) technology and advanced environmental protection to meet stringent reliability demands in dynamic, high-vibration environments. Product Details 1. VPI Process & Triple-Protection Design The reactor employs VPI technology to ensure deep epoxy resin penetration, achieving 3500VAC insulation resistance (IEC 61869-2 compliant) and exceptional moisture resistance. Combined with triple-protection coating (anti-corrosion, anti-salt spray, anti-UV), it withstands harsh conditions in tunnels, coastal areas, and underground stations. 2.High-Performance Rail Adaptability Engineered for 700A continuous current with 25× overload capacity (17.5kA), the reactor stabilizes DC bus voltage in traction converters, minimizing harmonics and voltage spikes. Its IP66-rated compact housing and vibration-damped core design ensure seamless integration into confined railcar spaces while enduring shocks up to 5G acceleration. Operation Environment A)  Altitude: Not exceeding 1000m, shall be derating used if above 1000m; B)  Ambient Temperature: -25ºC~55ºC. 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.
