Unmatched Performance Metrics

Partial Discharge Control

Maintains < 10pC PD level at 100% rated voltage (per indoor acceptance test protocols with specialized PD measurement methods).

Thermal Management

• Winding temperature rise: < 80K

• Transformer oil rise: < 55K

• Epoxy tube surface rise: ≤40K

Duty Cycle: 1 hour ON / 1 hour OFF (max 3 cycles/day at full 45kV/30A rating)

Robust Mechanical Design

• Iron Core with Segmented Air Gap – Precise magnetic flux control

• Copper Lead-Wire Windings – Low-loss performance

• Oil-Immersed Iron Tank – Superior heat dissipation vs epoxy designs

• Integrated Features:

• Breather capsule for oil expansion

• Heavy-duty lifting hooks

• Shock-resistant transport design

Key Advantages Over Epoxy Tube Reactors

Typical Applications
