50-2500kVA/35kV Oil Immersed Double Winding Transformer

This 50–2500kVA/35kV oil‑immersed double‑winding transformer is purpose‑built as a high‑performance power distribution solution for high‑load, harsh operating scenarios, including industrial power systems, new energy power stations, and rail transit infrastructure. Engineered to endure sustained heavy‑duty operation and complex grid conditions, it delivers stable, continuous power output while directly solving the longstanding pain points of high energy waste, excessive operational noise, and insufficient reliability seen in conventional transformer products.
Core Advantages (With Data & Practical Value)

Top‑Tier Energy Efficiency & Cost Savings
Fully certified to GB 20052-2020 Level 1 energy efficiency standards, plus the internationally recognized IEC 60076 and ISO 45001 specifications, this unit leads the industry in low power consumption. Rigorous performance testing confirms its no‑load loss is reduced by 30% compared to traditional models. This dramatic drop in energy loss delivers tangible benefits: lower daily power consumption, substantial cuts in long‑term operational electricity costs, and a smaller carbon footprint for your facilities across the transformer's full service life.

Ultra‑Quiet Operational Performance
Through optimized structural design and high‑grade component matching, the transformer's operating noise is lowered by 4 decibels (dB) against standard alternatives. This improvement creates a quieter on-site working environment, making it especially well‑suited for noise‑sensitive applications such as urban rail transit and industrial zones near residential or commercial areas.

Superior Thermal Stability & Extended Service Life
It boasts exceptional thermal control, with its temperature rise index strictly limited to below K65. Precise temperature management slows insulation material aging, strengthens resistance to overloads and extreme working conditions, drastically improves long‑term running stability, and effectively prolongs the product's service life.

Technical Features
● Oil‑immersed cooling system: Delivers efficient heat dissipation to maintain stable performance under continuous high loads.
● Double‑winding structure: Ensures balanced power transmission, strong anti‑interference performance, and excellent compatibility with power grids.
● High‑grade magnetic core & optimized circuit design: Minimizes energy loss and maximizes energy conversion efficiency.
● Full standard compliance: Meets strict national and international safety, performance, and quality benchmarks for global application and reliable operation.
This oil‑immersed transformer fully fulfills your core demands for energy saving, consumption reduction, and high‑reliability power distribution, serving as the ideal choice for critical high‑load power scenarios.

Typical Application Scenarios

Thanks to its robust performance, high operational stability and excellent adaptability to heavy-duty working conditions, this 35kV oil-immersed transformer is widely applied in a diverse range of key power scenarios.
