Product Description
Product Overview
300kVA three-phase pad-mounted oil type step-down transformer designed for reliable power distribution from 12470V to 208V. This compact, fully insulated unit offers exceptional performance in utility and industrial applications.
Key Performance Features
  • Compact design with approximately one-third the volume of European-style transformers of equivalent capacity
  • Fully sealed, fully insulated construction eliminates need for safety barriers
  • Multiple power supply configurations including terminal power supply, ring network, or dual power supply options
  • S11 oil-immersed power transformer with low loss, low temperature rise, and strong overload capacity
  • Dual fuse protection system with backup protection fuse and plug-in fuse featuring current and temperature dual sensitivity
  • 200A cable connectors support plug-and-unplug under load with load switch and isolation switch capabilities
  • Dyn11 winding connection and three-phase four-column core structure for stable operation under asymmetric loads
  • Anti-corrosion cabinet design with special spray paint treatment suitable for various environmental conditions
