How To Choose Oil-Immersed Transformer?

Oil-immersed transformer is suitable for power system, industrial and mining enterprises, scientific research departments and other relative high voltage electrical equipment, electrical components, insulation materials for power frequency or DC high voltage insulation strength test. However, when choosing an oil-immersed transformer, many users do not know how to choose. The following oil-immersed transformer manufacturers for you to introduce in detail.

1, the service life of the transformer is particularly short: because the inferior products are made of all aluminum and half copper and half aluminum winding materials, the transformer coil is much shorter than the coil life of the qualified transformer, and the service life of the inferior transformer is generally only about two years.
2, the transformer is burned in the rated power: because the inferior transformer is mostly made of aluminum wire as a material, the performance of its products is particularly weak in terms of short-circuit resistance, the ordinary qualified transformer can withstand at least more than the rated design of 20* overload capacity, and the inferior transformer once overloaded, the transformer coil is easy to burn.
3. Transformer loss is larger than the loss parameter on the nameplate: most transformers especially use inferior or old silicon steel sheets, resulting in no-load loss and load loss that are much larger than ordinary qualified products, virtually increasing a lot of costs to customers.
