SC(B) Epoxy Cast Resin Dry-Type Transformer — Details

Overview

Our SC(B) series dry-type transformers use advanced vacuum pressure impregnation (VPI) and epoxy resin casting technology to deliver safe, reliable, and maintenance-free power transformation for indoor applications.

Key Features

  • Zero Oil, Zero Pollution: No flammable oil means no fire risk and no environmental contamination
  • Maintenance-Free: Epoxy cast resin coils resist moisture, dust, and corrosive environments
  • Low Noise: Optimized core clamping design achieves noise levels below 50dB
  • Self-Extinguishing: Class E2 environmental rating — safe for hospitals, schools, and underground installations
  • Compact Design: Smaller footprint than oil-immersed equivalents, ideal for space-constrained locations

Applications

  • Commercial buildings and shopping malls
  • Hospitals and healthcare facilities
  • Data centers and server rooms
  • Underground transport systems (metro, tunnels)
  • High-rise residential buildings
  • Clean room and semiconductor facilities

Temperature Monitoring

Optional intelligent temperature controller provides:

  • Real-time winding temperature display
  • Over-temperature alarm and trip protection
  • Automatic fan control (AF cooling mode)
  • RS485 communication for SCADA integration
