Oil-Immersed Sealed Power Transformer Product Description

General Description
three-phase oil-immersed sealed power transformer is widely applied in 10kv, 20kv and 35kv power transmission and distribution system, worked as power and lighting for residential areas, business streets, industrial and mining enterprises.
It adopts new insulation structure and anti-short circuit ability is increased. All the fasteners are anti-loose treated.
It is completely sealed type. Compared with traditional oil-immersed transformers, it does not have oil conservator, oil tank corrugated plate is used as cooling and heat dissipation element. The corrugated plate is elastic, it will swell and shrink according to the transformer oil volume change, so the transformer is isolated from air, oil degradation and insulation aging are prevented and slowed down.

FAQ

Q: What is a Medium Voltage Sealed Power Transformer?

A Medium Voltage Sealed Power Transformer is a device that helps to change high voltage electricity into lower voltage electricity for safe use in homes and businesses. It usually operates with voltages around 15.6kV, 17.5kV, or 20kV and has special oil inside that cools and protects its parts.

Q:How does the oil immersion work in these transformers?

A:The oil inside the transformer helps to keep it cool and protects it from damage. When the transformer runs, it creates heat, and the oil absorbs this heat, allowing the transformer to work better and last longer.

Q:What are the benefits of having a sealed power transformer?

A:A sealed power transformer is designed to be safe and reliable. It prevents outside air from entering, which helps to keep the oil clean and the equipment in good condition. This reduces maintenance needs and extends the transformer’s life.

Q:Where can I use Medium Voltage Sealed Power Transformer?

A:These transformers are mainly used in power distribution systems for residential areas, business locations, and industrial facilities. They ensure that electricity can be safely used across different settings.
