Features of Cast Resin Dry Transformer

Safety: Cast resin dry transformers use cast resin as insulation material, which is non-flammable and does not pose safety hazards such as oil explosions, making it particularly suitable for fire-sensitive environments like commercial buildings and underground projects.

Environmental friendliness: Because they do not use oil as a cooling medium, cast resin dry transformers do not cause environmental pollution during operation, aligning with modern environmental protection requirements. Additionally, the cast resin material is recyclable, reducing resource waste.

High efficiency: Cast resin dry transformers have a high cooling efficiency, enabling stable operation under higher load conditions with low energy consumption and high energy conversion efficiency. Moreover, the cast resin structure provides good heat dissipation, contributing to the overall performance of the transformer.

Application of Cast Resin Dry Transformer

Urban power grids

In urban power supply systems, due to space constraints and high safety requirements, cast resin dry transformers are often the preferred choice for distribution transformers, ensuring the stability and reliability of urban power supply.

Industrial plants

More and more industrial enterprises consider safety and operational efficiency when constructing new plants, opting for cast resin dry transformers as power conversion devices to ensure stable electricity supply during production processes.

Renewable energy

With the development of renewable energy technologies, cast resin dry transformers are also used in wind and solar power generation systems, effectively facilitating energy conversion and transmission.

The Working Principle Of Resin Cast Resin Dry Transformers

The cast resin dry transformer insulates its windings and core without the need for fluids. Instead, a sealed cast epoxy resin that contains the windings and core is used.

In places with significant levels of moisture, cast resin cast resin dry transformers are used. It’s a result of the epoxy glue that surrounds its principal and secondary windings (non-hygroscopic). The winding can’t get wet because of the encapsulation.

Power ranges from 25 KVA up to 12,500 KVA, and the insulation class is F. (90oC Temp. Rise).

Low loss and low partial discharge. As a result, efficiency is excellent. It poses no risk of a fire hazard since non-flammable winding insulation is used. It can therefore be installed indoors.

FAQ

Q: What is the difference between dry type transformer and cast resin?

A: The cast resin transformers are also dry type transformers. These transformers are also constructed by encapsulating the transformer winding into an epoxy resin but without the application of vacuum pressure. The vacuum pressure in VPI transformers ensures that the resin fills all the spaces of transformer winding.

Q: What is the life expectancy of a cast resin transformer?

A: With low consumption and reduced CO2 emissions, cast resin transformers also have a long service life of 20+ years.

Q: What are the requirements for a dry type transformer?

A: The floor area should be smooth and level, and able to support the weight (in pounds/sq. ft) of the transformer. Reinforced concrete is preferable. Dry type transformers must be installed in a level upright position in an area with free air circulation.

Q: How to maintenance a dry type transformer?

A: Visually inspect cover louvers, screens, and internal coil cooling ducts for dust build-up. ...
Once de-energized, vacuum out as much of the dust as possible.
Clean the transformer with a brush or lint-free rag. ...
In inaccessible areas, blow dry air into the unit.
