How to select oil-immersed transformers of different specifications according to different environments

Oil-filled transformers are important electrical equipment, and they are used widely in many different places. They are critical in transforming electrical energy at one voltage level to another and thereby enabling efficient and safe electricity transmission. At Xuzhou Railway Electric, we know how to select the proper oil-immersed transformer to fit into various places so as to maintain its top performance and life span.

A review on oil-immersed transformers and their: applications and environments

Oil-filled transformers are those types of transformers which facilitate the supply and transmission of electricity by varying the voltage level by means of electrical induction. They are oil filled type transformers which mean they carry insulating and cooling oil in it during its operation. These transformers are applied in a variety of applications including industrial, residential, and outdoor landscape.

Choosing the appropriate oil-immersed transformer for each environment is an important consideration for maintaining both its life and performance. The ambient conditions such as temperature, humidity and corrosive substances in the air may influence the performance of the transformer a lot.

Points to note when purchasing oil-immersed transformers in bad weather

Specifications to Consider When Selecting an Oil-Immersed Transformer for Extreme Weather Conditions By Jeffrey G. Edwards, P.E., sales and marketing manager When selecting a transformer for extreme outdoor conditions, it is important to consider temperature variations, moisture, and the potential for exposure to corrosive substances. Outdoor applications for Transformers The design of Transformers which are to be used outdoors must be suitable for such conditions so that they operate reliably.

How to select voltage level, capacity and power for oil immersed transformers at different places?

It is very important to choose the appropriate voltage and power levels of oil immersed transformers, as a proper voltage is necessary for efficient working of the electrical system in an area. Under or over-rated transformers in an application might be inefficient, overheat, or worst case damage the equipment.

It is important to evaluate the electrical need in the place, before purchasing an oil-immersed transformer. Take into account the loading, voltage variations, and possible future expansion needs to determine the proper voltage and power ratings for your transformer.

Influence of the environmental conditions on the performance and efficiency of oil-immersed transformers

Performance and effciency of oil-immersed transformers may deteriorate under the inuence of environmental variables like temperature, humidity and/or corroding compounds. Overheating and thermal stress can occur at high temperatures, and breakdown of the insulation and corrosion of the insulation can occur from moisture and corrosive substances which can adversely impact transformer reliability.

Selecting transformers that are robust to harsh field conditions can help reduce the affect of the environment on the performance of oil-immersed transformers. Routine transformer maintenance and monitoring can also prove helpful in early detection of the suspect problem before expensive downtime occurs.

A case study of selection of oil-immersed transformers under different environmental conditions and its successful Application

We have chosen and installed oil-immersed transformers for specific environmental conditions and applications with many clients at Xuzhou Railway Electric. We have worked with our clients to choose a weatherproof oil immersed transformer and in one case this was for an industrial outdoor application. The transformer was also engineered to operate in highly fluctuating temperature and humidity conditions to provide maximum operational capability in the grueling environment.

For another client we selected an oil-immersed transformer of improved insulation for a corrosive environment in an additional case study. Special paint, coatings and materials were applied in accordance with the highest standards to prevent corrosion and promoting longevity and reliability.

Based on environmental factors, voltage levels and outside conditions that affect transformer function, we also provide personalized advice to customers so that they can select the most suitable oil immersed transformers for their use. Xuzhou Railway Electric are dedicated to offering high-performance transformers that are suitable for various conditions and environments, carry on the functions, and operate for many years.
