Three-dimensional Triangle Wound Core Structure and Advantages
Optimization of magnetic circuit :
1.There is no joint between the three dimensional volume of the core layer, uniform distribution of the magnetic circuit. There is no obvious high resistance area and no distortion of the magnetic flux density of the joint.
2.The direction of the magnetic flux is completely consistent with the orientation of the silicon steel sheet.
3.The length of the three-phase magnetic circuit is exactly the same, and the length of the three-phase magnetic circuit is the shortest.
4.The three-phase magnetic circuit is completely symmetrical, and the three air current is completely balanced.
Low loss, energy savings remarkable:
1. Lower Core Loss: Aligned magnetization and uniform flux distribution reduce iron loss by 10-20%.
2.Material Savings: Special 3D structure cuts yoke material by 25%, with corner core weight only 6%.
3.Improved Magnetic Performance: High-temperature annealing enhances silicon steel’s magnetic properties beyond factory specifications.
4.Superior No-Load Performance: No-load loss is 25-35% lower than national standards, and max load current can be cut by 92%.
Low noise:
The source of noise caused by transformer body vibration is:
1.Magnetic expansion of the silicon steel sheet causes core vibration, producing noise.
2.Electromagnetic attraction at joints and laminations due to leakage causes core vibration and noise.
3.Excessively high working magnetic density near saturation, along with large leakage, results in noise.
The three-dimensional wound core, made from continuously rolled silicon steel without seams, avoids the noise of laminated cores. Its symmetrical three-phase magnetic circuit and well-designed magnetic density significantly reduce noise.
High overload ability:
1.The product itself has very low heat: the winding core transformer’s no-load loss, no-load current are both very small, so the product itself is very low heated.
2.Three-phase coil is like three chimney delta shaped, so an airway chimney is formed in the coil. The core yoke has a temperature difference of 30-40℃, which causes strong cross-ventilation. Cold air goes up to the warm side, the heat is radiated from the inner bevel of upper yoke.
Compact structure, small location :
The special-designed three-dimensional core makes compact structure products reasonable layout, the transformer body occupied is 10-15% less than traditional products, body height 10-20%. If installed in the substation box, the substation box can deduce nearly 1/4.
Anti-theft :
The copper coil is wounded onto the iron. The copper coil is hard to taken out without big professional equipment

7.Low voice, energy saving, low cost and anti-theft
Stacked Core Transformer
Advantages :
1.Easy assembly. Range no standard range of design exists due to the diversity of design requirements.
2.The materials magnetic properties are recover by annealing in nitrogen furnace. We produce single phase cores ranging from 10KVAto 5000KVA, and the three-phase cores ranging from 10KVAto 40MVA.
R-type Iron Core Transformer
Application :
Widely used in single-phase or three-phase S11, S13 distribution transformers.
Advantages :
It is an environmental and energy – saving products. With different widths and multi-layer symmetrical winding, the cross section is approximately circular in the symmetrical step.The coil is directly wind on the core which can reduce the length of the coil. The magnetic circuit is completely closed and no leakage flux. Efficiency of R-Core Transformer is usually more
