Key Advantages

1 Optimization of Magnetic Circuit
  • Seamless three-dimensional core layers ensure uniform magnetic circuit distribution without high resistance areas or flux distortion.
  • Magnetic flux direction aligns perfectly with silicon steel sheet orientation.
  • Equidistant three-phase magnetic circuits ensure balanced performance.
2 Low Loss & Remarkable Energy Savings
  • Iron loss reduced by 10-20% compared to laminated cores due to superior material alignment.
  • Core yoke material usage reduced by 25% through specialized 3D structuring.
  • High-temperature nitrogen vacuum annealing eliminates mechanical stress and refines magnetic domains.
  • No-load loss is 25-35% lower than national standards, with no-load current reduced by up to 92%.
3 Low Noise Operation
  • Continuous rolling process eliminates seams that cause vibration in traditional laminated cores.
  • Symmetrical magnetic circuit design significantly reduces operational noise, ideal for public environments.
4 High Overload Ability
  • Extremely low self-heating due to minimal no-load loss and current.
  • Delta-shaped three-phase coil creates a natural "chimney effect" for superior cross-ventilation and heat radiation.
5 Compact Structure & Small Footprint
  • Occupies 10-15% less floor space and 10-20% less height than traditional models.
  • Reduces the required size of substation boxes by nearly 25%.
6 Anti-Theft Design
  • Integrated winding design makes copper coil removal impossible without heavy professional equipment.

Frequently Asked Questions

Q1 What is the difference between S13 and S11 transformers?
The S13 transformer features significantly lower no-load losses compared to the S11 model. For example, at 30 KVA, the S13 no-load loss is 80W while the S11 is 100W. S13 achieves 25-35% lower no-load loss overall.
Q2 What voltage combinations are available?
It supports high-voltage inputs of 6 kV, 6.3 kV, 10 kV, 10.5 kV, and 11 kV (±5% tapping) with a 0.4 kV low-voltage output. Connection groups include Dyn11, Yzn11, and Yyn0.
Q3 How much energy can be saved with a 3D wound core?
It reduces iron loss by 10-20% and no-load loss by 25-35% compared to national standards. The maximum no-load current can be reduced by up to 92%.
Q4 Can it be used for renewable energy applications?
Yes, it is ideal for solar PV and wind power plants, converting variable energy into stable, grid-compatible electricity for smooth integration.
Q5 Why is the noise level lower?
The seamless, continuous winding process eliminates joint vibrations common in laminated cores. The symmetrical magnetic circuit further dampens operational sound.
Q6 Does the compact design affect performance?
On the contrary, the 3D core enhances performance while saving 10-20% space, making it perfect for urban substations and compact industrial sites.
