Our engineering team designed and manufactured a customized 10MVA 33/11kV Oil Immersed Power Transformer in accordance with IEC standards. The transformer features a high-efficiency silicon steel core, premium copper windings, and a robust insulation system to ensure excellent electrical performance and durability.
The transformer has been operating reliably since installation, delivering consistent performance and meeting all project requirements. The customer expressed satisfaction with the product quality, delivery schedule, and technical support.
The transformer is mainly used in utility substations, industrial plants, renewable energy projects, mining operations, and power distribution networks to step down voltage from 33kV to 11kV.
Yes. We can customize capacity, voltage ratio, impedance, cooling method, vector group, tap changer type, and other specifications based on project requirements.
Standard cooling methods include ONAN (Oil Natural Air Natural) and ONAF (Oil Natural Air Forced). Other configurations can be provided upon request.
Yes. Our transformers are manufactured in accordance with IEC 60076, IEEE, ANSI, and other applicable international standards.
Both copper and aluminum windings are available. Copper windings are generally recommended for higher efficiency and longer service life.
The transformer can be equipped with either an Off-Circuit Tap Changer (OCTC/NLTC) or an On-Load Tap Changer (OLTC) depending on system requirements.
Under proper installation and maintenance conditions, the transformer can typically operate reliably for more than 25 years.
Yes. The 10MVA 33/11kV transformer is widely used in solar power plants, wind farms, and other renewable energy applications.
Routine tests, type tests, and special tests can be conducted according to IEC or customer requirements, including ratio tests, insulation tests, impedance tests, temperature rise tests, and load loss measurements.
We provide test reports, technical drawings, operation manuals, nameplate data, packing lists, and other project-related documentation.
