6300kVA~100000kVA dual-winding transformer with OLTC

6300kVA~100000kVA Dual-Winding Transformer with OLTC 

When your power network demands exceptional reliability and precision, our 6300kVA~100000kVA dual-winding transformer with OLTC delivers enterprise-grade performance. Designed at Lijie Electric's 500,000-square-meter manufacturing facilities, these transformers feature advanced on-load tap-changing technology with ±4×2.5% or ±8×1.25% regulation ranges. Backed by over 160 engineers and validated by the National Transformer Quality Supervision and Inspection Center, our SSZ11 series achieves minimal partial discharge levels, reduced noise output below 65dB, and efficiency ratings exceeding 99.5%. With production cycles of 6–30 days and proven deployment across substations in 15+ countries, you gain power solutions that reduce operating costs while ensuring grid stability.

What Makes Our Large-Capacity Transformers Stand Out?

Precision Voltage Control

Your lattice steadiness depends on exact voltage administration. The coordinates OLTC framework permits real-time alterations without hindering control stream. This include demonstrates important amid crest request periods or when input voltages fluctuate.

You can select between two direction designs based on your particular necessities. The framework reacts inside milliseconds to keep up steady yield over all stack conditions.

Superior Designing Standards

We utilize Toshiba's investigation program combined with exclusive calculation programs to optimize each component. This incorporates the transformer center, windings, leads, and tank design.

The result? You get compact units with diminished weight that are less demanding to transport and introduce. Lower misfortunes interpret straightforwardly into decreased vitality costs for your operation.

Robust Development for Requesting Environments

Built for control plants, substations, and overwhelming mechanical offices, these transformers withstand cruel working conditions. The cooling systems—available in ONAN, ONAF, or OFAF configurations—adapt to your surrounding temperature requirements.

Three-phase dual-winding development guarantees adjusted stack dispersion. The YNd association bunch arrangement gives unbiased establishing alternatives for upgraded security.

Multi-Voltage Flexibility

Whether you're working with 35kV, 110kV, or 220kV systems, our 6300kVA~100000kVA dual-winding transformer with OLTC adapts to your infrastructure. This versatility eliminates the need for multiple transformer types in complex networks.

Each unit undergoes rigorous short-circuit withstand testing. You can trust these transformers to protect your investment during fault conditions.

Frequently Asked Questions

Q: How does OLTC improve my system's performance?

A: On-load tap changers allow voltage adjustments while the transformer operates under full load. This eliminates downtime and maintains stable output voltage despite input fluctuations, extending equipment lifespan and improving power quality.

Q: What cooling method should I select?

A: ONAN suits moderate loads with natural air circulation. ONAF adds forced air for higher capacity requirements. OFAF provides maximum cooling for continuous heavy loads in hot climates. We'll recommend the optimal solution based on your capacity and environment.

Q: Can these transformers operate in unattended substations?

A: Absolutely. Our product with OLTC units include intelligent monitoring interfaces compatible with SCADA systems. Low maintenance design and reliable protection systems make them ideal for remote installations.

Q: What documentation do I receive?

A: Each unit ships with factory test reports, installation drawings, operation manuals, and maintenance guidelines. All documents comply with international standards and support your commissioning process.

Q: How do you ensure quality control?

A: Every transformer undergoes routine type tests and short-circuit withstand testing at the National Transformer Quality Supervision and Inspection Center. Our quality management system follows GB/T 27922-2021 standards with multiple inspection checkpoints throughout production.
