Capacity Range: 6300KVA-125000KVA
Cooling Mode: ONAN/ONAF
Connection Group: YNd11
Energy Efficiency Class: High-Efficiency andEnergy-Saving Transformer
2. Product Features
Ultra-High Energy Efficiency, Cost Reduction and Efficiency Improvement
Uses high-quality silicon steel sheets, oxygen-free copper windings, and an optimized electromagnetic design. No-load and load losses are significantly lower than national standards, greatly reducing long-term operating costs. Additional investment can be recovered within 3–5 years.
On-Load Voltage Regulation, Stable Voltage
It adapts to new fluctuations in energy load and precise loads, ensuring high quality of power supply.
High reliability, high impact resistance
Reinforced winding with uniform ampere-turn distribution, excellent short-circuit and lightning impulse resistance. Hermetically sealed oil tank, low partial discharge (≤ 50 pC), hermetically sealed design suitable for harsh conditions.
Low noise and environmentally friendly
Uses a step-lap core with hardening treatment, noise level exceeds national standards. Hermetic sealing reduces oil pollution;Low-loss designContributes to achieving carbon peak and carbon neutrality goals.
Intelligent operation and maintenance, low operation and maintenance cost
Standard monitoring of oil temperature, oil level, gas relay, and winding temperature, supporting remote monitoring. Hermetically sealed design requires no frequent oil replenishment and allows for long maintenance intervals.
