HJ-AMT-O Series Amorphous Alloy Transformer – Oil
Up to 35kV / Ultra-Low Loss / High ROI / Hermetically Sealed
The HJ-AMT-O Series Amorphous Alloy Transformer (Oil-Immersed) represents the pinnacle of energy-efficient power distribution. By replacing traditional silicon steel with an advanced amorphous metal ribbon core, it astonishingly reduces no-load (standby) losses by up to 70%-80%. Designed within a hermetically sealed, maintenance-free corrugated tank, it is the ultimate high-ROI solution for grids with continuous energization but fluctuating loads.
Ideal for Energy-Conscious & Fluctuating Loads:
- ✓ Solar PV & Wind Power Collection Networks
- ✓ Rural Electrification & Low-Density Distribution
- ✓ Utility Grid Upgrades targeting Carbon Footprint Reduction
- ✓ Industrial Parks with Variable Shift Operations
1. Breakthrough Amorphous Metal Core
The secret to its extreme efficiency lies in the core material. Unlike the crystalline structure of traditional Grain-Oriented (CRGO) silicon steel, the amorphous alloy possesses a randomized, glass-like atomic structure. This allows for incredibly easy magnetization and demagnetization, slashing hysteresis and eddy current losses, and reducing overall no-load losses by up to 70% to 80%.
2. Maximized ROI for Fluctuating Grids
In applications like renewable energy or rural grids, transformers remain energized 24/7 but only carry peak loads for a few hours daily. During those long standby periods, standard transformers waste massive amounts of power. The HJ-AMT-O virtually eliminates this standby waste, delivering a rapid Return on Investment (ROI) through substantial long-term energy savings.
3. Global Voltage Matching & Compliance
We seamlessly merge cutting-edge amorphous technology with our mature global manufacturing platform. Whether your regional utility requires 11kV, 13.8kV, 20kV, 22kV, or 33kV primary voltages, we custom-engineer the HJ-AMT-O to match your exact national grid specifications and vector group requirements flawlessly.
4. Hermetically Sealed & Maintenance-Free
Sharing the rugged architecture of our standard ODT series, the core and windings are housed in a fully sealed corrugated oil tank. This isolates the insulating oil from atmospheric oxygen and moisture, completely preventing oil degradation and oxidation, thereby ensuring decades of zero-maintenance operation.
Global Factory Acceptance & Turnkey Support
Every HJ-AMT-O transformer is subjected to stringent factory acceptance testing (FAT) per IEC 60076 standards, with a special focus on validating its ultra-low no-load loss parameters. We provide comprehensive FAT documentation and carbon-reduction calculation estimates to support your project's ESG and green energy compliance.
