6300 kVA transformer
Product advantages:
1. Operating efficiency ≥ 97%, highly efficient and energy-saving with minimal losses. It saves costs in long-term operation and provides outstanding benefits throughout the entire lifecycle, meeting carbon neutrality requirements.
2. Voltage stability and controllability: can be equipped with on-load tap changers, allowing online voltage regulation without shutdown to stabilize secondary voltage and adapt to load fluctuations; it can also use no-deviation voltage regulation, balancing stability and economy.
3. Stable design, short-circuit resistant: high-quality iron cores and oxygen-free copper windings, with high mechanical strength and short-circuit resistance, low failure rate, and extended equipment lifespan.
4. Hermetic design, minimal maintenance and convenience: sealed oil tank prevents leakage and moisture, with a long maintenance-free period, significantly reducing daily workload and operating costs.
6. Compact design, easy installation and transportation: small size, light weight, simple to install and transport.
