35kV oil-immersed power transformer

35kV oil-immersed power transformer

35kV oil-immersed power transformer products have the characteristics of "four low and one high", that is, low loss, low noise, low temperature rise, low local discharge, high reliability, no lifting core, no leakage and so on. The product uses advanced design software for electromagnetic calculation, and computes and analyzes the main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, short-circuit thermal stability and dynamic stability strength of the transformer by computer to ensure the design margin of the transformer, so as to ensure the safe and reliable operation of the transformer.

Frequently Asked Questions

Answers to Common Inquiries About Our Transformers and Services

A: Oil leakage of oil-immersed transformers is generally caused by the following two reasons: one is sand holes in the castings or pores in the welds, and the other is poor sealing.

A: First, find out the cause. If it is caused by improper placement of the sealing gasket, just put the sealing gasket in the right place, press it evenly and tighten it.

A: Protects the Solid Insulation – The transformer oil protects the solid insulation (paper). This is by far the most important function of the oil. Once the integrity of the paper is gone, you really only have two options to bring the transformer back to a good reliable piece of equipment: replace or rewind it.

A: Typical transformers have around 10,000 gallons of oil, but this depends on the scale of the substation whether for residential or industrial power transmission.

A: In reality, transformers running at underload hampers its longevity and efficiency. When a transformer is not correctly sized, the underloaded condition would result in high harmonic currents. This may also cause heating of transformers. All of this sum up to cause poor performance of the transformer.

A: Moisture in a Transformer Moisture is a significant concern for power transformers and can lead to unexpected failure of equipment and unplanned outages. Excessive moisture in the oil of a transformer reduces the oil's dielectric strength. This introduces the opportunity for flashover and arcing.
