How long is the quality assurance of the transformer?
We provide a warranty of up to 18 months. The warranty period is 12 months after the transformer is put into production or 18 months after delivery.
Can three-phase oil immersed transformers be used in renewable energy applications?
Yes, they are suitable for various applications, including renewable energy systems, to ensure efficient energy conversion and distribution.
How often should maintenance be performed on these transformers?
Regular inspections and maintenance should be conducted at least once a year, along with oil quality testing.
What are the benefits of using biodegradable insulating oils?
Biodegradable oils reduce environmental impact and are safer for the ecosystem in case of leakage.
How does oil contribute to the performance of transformers?
Oil acts as both an insulator and a cooling medium, helping to dissipate heat and protect winding materials.
What is the primary function of a three-phase oil immersed transformer?
The primary function is to convert high voltage electricity to lower voltage levels for safe distribution and use.
Are you a trade company or manufacturer?
We are a professional manufacturer with our own factory.
When can I get a price？
