Home > SBH 10kV Amorphous Alloy Oil Immersed Distribution Transformer (30-2500 kVA)
Product Overview:
The 10kV Amorphous Alloy Oil Immersed Transformer is a premium, highly efficient outdoor power distribution solution. Engineered to replace conventional silicon steel core transformers, this unit leverages advanced amorphous metal strips to dramatically cut no-load losses by approximately 65%.
Built with a fully hermetically sealed corrugated tank and vacuum-filled insulating oil, it isolates active components from atmospheric pollution and moisture. This renders the transformer entirely maintenance-free and highly reliable even in extreme, humid, or heavily polluted outdoor environments. It is the ideal eco-friendly power equipment for rural distribution networks, urban grids, and remote facilities where load fluctuations are high and routine maintenance is difficult.
Key Advantages:
• Advanced amorphous alloy core reduces no-load energy losses by ~65%
• Low-voltage copper foil winding enhances short-circuit withstand capability
• Fully sealed, maintenance-free oil tank structure extends service life
• Vacuum oil injection completely eliminates air bubbles to stabilize insulation
• Dyn11 vector group minimizes harmonic impacts and improves power quality

Traditional distribution networks suffer from continuous "vampire" energy drain caused by transformer idling losses. This amorphous alloy core distribution transformer solves the problem by utilizing rapidly cooled metallic glass strips. Because amorphous metals lack a crystalline structure, they offer incredibly low magnetic resistance. The result is a staggering ~65% reduction in no-load loss (iron loss) compared to standard S11 series silicon steel transformers, yielding massive long-term operational savings and reducing the grid's carbon footprint.
One of the main causes of transformer failure is mechanical deformation during grid fault conditions. To combat this, the low-voltage coils of our amorphous alloy transformer are wound using premium copper foil rather than standard wire. Foil winding perfectly balances the axial ampere-turn distribution and drastically reduces magnetic flux leakage. This design immensely boosts the transformer's mechanical rigidity, allowing it to easily withstand the severe electro-dynamic forces generated by sudden short circuits.
Designed specifically for harsh outdoor applications, the transformer features a completely sealed corrugated tank that integrates the main body with the cover. The insulating oil undergoes a strict vacuum injection process, pulling out all residual air bubbles and moisture from the windings. Because the oil never contacts the outside atmosphere, it will not oxidize or absorb moisture. This allows the transformer to operate reliably in humid, coastal, or heavily polluted areas with zero routine oil maintenance required.
Rural and modern urban grids frequently encounter unbalanced loads and harmonic distortions from non-linear devices. Configured with a Dyn11 vector group, the delta connection on the primary winding provides a closed loop for third-harmonic currents to circulate, preventing them from entering the high-voltage grid. This significantly improves overall power quality and ensures a stable, clean voltage supply to downstream users.
Areas with severe load fluctuations—such as agricultural zones or seasonal industrial parks—often stress conventional distribution equipment. The exceptionally low idling losses of the amorphous core mean the transformer runs highly efficiently even when lightly loaded. Coupled with its robust environmental adaptability (operating between -25°C to +40°C), this transformer provides unparalleled reliability where grid power is inconsistent or daily maintenance is impractical.
The primary advantage is massive energy savings. The amorphous alloy core reduces no-load losses by approximately 65% compared to conventional silicon steel cores. For rural or urban distribution networks with fluctuating loads, this translates to significant reductions in operating costs and a lower carbon footprint.
The low-voltage windings are constructed using high-quality copper foil instead of standard wire. This foil-winding technique perfectly balances the axial ampere-turn distribution, minimizing leakage flux and dramatically enhancing the transformer's mechanical ability to withstand sudden short-circuit impacts.
No. This transformer features a fully hermetically sealed corrugated tank. The insulating oil is vacuum-filled to eliminate any air bubbles, completely isolating the oil and active parts from atmospheric moisture and contaminants. This design is virtually maintenance-free throughout its service life.
Thanks to its robust sealed enclosure and strong environmental adaptability (operating from -25°C to +40°C), it is ideal for outdoor distribution systems. It is particularly well-suited for humid, heavily polluted areas, or remote locations where regular daily maintenance is difficult to perform.
