Low Loss Transformer
,0.4kV Transformer
- Maximum Energy Efficiency: Utilizing high-permeability silicon steel, the S11 design drastically cuts no-load losses, translating into significant long-term operational savings for grid operators.
- Superior Load Stability: Specifically tuned for 1000kVA and 1250kVA capacities, it provides consistent output voltage even during sudden demand spikes in infrastructure operations.
- Hermetically Sealed Maintenance-Free Design: The vacuum-sealed corrugated tank prevents oil oxidation, extending the insulation life to over 30 years without the need for periodic oil filtration.
- High-Grade Copper Windings: Built with 99.9% oxygen-free copper, ensuring high thermal conductivity and the mechanical strength required to resist short-circuit stresses.
- Rated Capacities: 1000 kVA / 1250 kVA (Dual capacity options available)
- Voltage Ratio: High Voltage (HV) 20kV / Low Voltage (LV) 0.4kV (400V)
- Core Engineering: Multi-step lap joints reduce noise levels and magnetic flux leakage, surpassing international IEC standards
- Vector Group: Dyn11 or Yyn0, providing flexible grounding and harmonic suppression options for various grid types
- Corrugated Tank Technology: Elastic radiator fins automatically adjust to oil thermal expansion, maintaining constant internal pressure
- Surface Protection: C4-grade industrial anti-corrosion coating prevents rust in high-humidity or coastal substation environments
Operational Challenge: In regions with heavy sandstorms and high dust concentration, particles often accumulate in traditional oil conservators, causing seal degradation and hazardous oil leakage.
- Elimination of External Breathers: Our fully sealed corrugated tank eliminates the traditional conservator. By removing the air-breathing path, we completely block fine sand and dust from contaminating the internal mineral oil.
- Reinforced Double-Weld Seams: To prevent leakage under extreme temperature fluctuations, all tank joints are reinforced with double-pass robotic welding and subjected to 0.05MPa pressure testing.
- Anti-Dust Bushing Shields: High-voltage bushings are equipped with protective skirts to prevent dust accumulation, reducing the risk of flashovers and electrical tracking in arid climates.
