High Efficiency SCBH15 Nanocrystalline Alloy Dry-Type Transformer 10kV - China Suppliers & Factory
Product Features
This series of transformers features an optimized structural design, combining advanced materials and manufacturing processes to deliver outstanding electrical performance, mechanical stability, and adaptability. It is widely suitable for industrial production, commercial buildings, municipal engineering, and similar applications. Below is an overview of its core structural components and optional configurations.
1. Iron Core
The core is wound from high-quality nanocrystalline alloy strips, known for ultra-high magnetic permeability, low coercivity, and minimal core loss. This reduces no-load loss by over 30% compared to traditional silicon steel. Available in three-phase five-column or three-phase three-column wound designs, the rectangular cross-section is optimized through electromagnetic simulation to ensure uniform magnetic flux distribution, reduce leakage, and lower losses. The wound structure enhances mechanical strength, suppressing vibration and noise.
2. High-Voltage Coil
The high-voltage coil adopts a segmented cylindrical structure for even voltage distribution and improved withstand capacity. It is manufactured using vacuum casting with thin insulation and hermetic sealing, which enhances heat dissipation and protects against moisture and dust. For high-capacity windings, axial air ducts are integrated to promote airflow and prevent local overheating. This results in high voltage withstand performance, extremely low partial discharge (≤5pC), excellent dust resistance, and efficient cooling.
3. Low-Voltage Coil
The low-voltage coil uses a foil structure with DMD prepreg hot-pressed between layers, effectively resolving ampere-turn imbalance common in traditional wire-wound designs. The foil ensures uniform current distribution, reduces localized losses, and eliminates axial winding angles, significantly lowering axial electromagnetic forces during short circuits. The hot-pressed process enhances interlayer bonding, forming a solid, mechanically stable coil with low additional loss.
4. Outer Casing & Configuration
The enclosure can be customized in materials such as ordinary steel (cost-effective for indoor use), aluminum alloy (lightweight, corrosion-resistant for outdoor/humid environments), or stainless steel (durable for harsh conditions like coastal or chemical plants). Protection levels include IP20 (indoor, blocks solids >12.5mm) and IP23 (outdoor/semi-outdoor, protects against angled water ingress). High- and low-voltage busbar interfaces can be flexibly configured to match user layout needs, simplifying installation and improving system compatibility.
