Transformer Cooling

Overview

The transformer cooling system is the most stringent application for fans in rail vehicles as any fan failure would result in a loss of electrical power. On EMUs / DMUs, the implementation on the roof requires the most efficient corrosion protection of materials to ensure long lasting life.

  Axipal BZiThe Axipal® BZi is a range of aerofoil axial flow fans with adjustable pitch angle blade. Its low and medium pressure performance makes Axipal® BZi suitable for all air movement applications with clean, dusty or humid air at temperatures from -20°C to 200°C.
• 
  JM AerofoilJM aerofoil® impellers are high-pressure die cast of aluminum and consist of blades, hub and clamp plate. The JM impeller is manually adjustable through the full range of pitch angles. All impeller components are X-rayed using real time radiography, and examined to ASTM E-155, prior to machining to assure casting integrity and quality. Impellers are precision balanced as a fan assembly to minimize vibration levels and assure smooth operation.
