FAQ
What is a 3D wound core oil immersed transformer?
A 3D wound core oil immersed transformer is a three phase oil immersed distribution transformer with a three-dimensional triangular wound core structure. It is designed to reduce no-load loss, no-load current and operating noise.
What is the advantage of a three dimensional wound core transformer?
The three dimensional wound core transformer has a balanced magnetic circuit and continuous wound core structure. This helps reduce magnetic resistance, improve energy efficiency and support stable long-term operation.
Is this transformer different from a traditional oil immersed transformer?
Yes. A traditional oil immersed transformer often uses a stacked laminated core. A 3D triangular wound core transformer uses a continuous wound core arranged in a triangular structure, which improves magnetic balance and helps reduce no-load loss and noise.
What capacity range is available?
TAILI can provide 30kVA to 3000kVA oil immersed transformer solutions. Customized capacity ratings can also be designed according to project requirements.
Can you provide 10kV and 35kV oil immersed transformers?
Yes. TAILI supplies 10kV oil immersed distribution transformer and 35kV oil immersed distribution transformer options for utility grids, industrial facilities, renewable energy projects and substations.
What standards can the transformer meet?
The transformer can be designed according to IEC, IEEE, ANSI and DOE requirements. CE, SGS and CNAS certificate support can be provided according to project needs.
What oil can be used in the transformer?
Mineral oil is commonly used. Vegetable oil, silicone oil or other specified insulating oil can also be selected depending on project requirements and local standards.
Can the transformer be customized for renewable energy projects?
Yes. The transformer can be customized for solar power, wind power and distributed energy systems, including voltage ratio, capacity, tank structure, protection accessories and outdoor installation requirements.
