Advantages

🌀 1. Optimization of Magnetic Circuit
  • Uniform distribution of the magnetic circuit with no high resistance areas.
  • Magnetic flux direction is completely consistent with silicon steel sheet orientation.
  • Shortest and completely symmetrical three-phase magnetic circuit.
📉 2. Low Loss, Energy Savings Remarkable
  • Iron loss reduced by 10–20% compared to laminated cores.
  • No-load loss is 25–35% lower than national standards.
  • High-temperature nitrogen vacuum annealing eliminates mechanical stress.
🔇 3. Low Noise
  • Continuous tightly rolling silicon steel strip creates a seamless core.
  • Eliminates seams that typically produce noise in laminated designs.
  • Symmetrical magnetic circuit design greatly reduces overall product vibration.
💪 4. High Overload Ability
  • Minimal heat generation due to very small no-load current.
  • Delta-shaped coil structure creates natural "chimney" ventilation for cooling.
📐 5. Compact Structure
  • Footprint is 10–15% less than traditional products.
  • Body height reduced by 10–20%, saving installation space in substation boxes.
🔒 6. Anti-Theft
  • Integrated copper coil winding onto the iron core makes removal extremely difficult without professional equipment.

Frequently Asked Questions

Q: What is the difference between S13 and S11 transformers?
The S13 transformer features significantly lower no-load losses. For a 30 KVA unit, the S13 loss is 80W compared to 100W for S11, making it more cost-effective for long-term energy savings.
Q: What voltage combinations are available?
It supports high-voltage inputs of 6kV, 6.3kV, 10kV, 10.5kV, and 11kV with a ±5% tapping range, and a standard low-voltage output of 0.4kV.
Q: How much energy can a 3D wound core transformer save?
It reduces no-load loss by 25–35% compared to national standards and can reduce the maximum no-load current by up to 92% compared to traditional laminated designs.
Q: Is it suitable for renewable energy applications?
Yes, it is ideal for solar PV and wind power plants, as it efficiently converts unstable energy outputs into grid-compatible electricity.
Q: Why does it produce less noise?
The seamless, jointless construction of the 3D wound core eliminates the electromagnetic vibration and leakage flux commonly found in traditional laminated cores.
Q: What rated capacities are available?
We offer a range from 30 KVA up to 1600 KVA, covering all standard industrial and residential requirements.
