Cast-resin Transformers: Introduction
- Dry-type transformers, also known as cast-resin transformers, are power transformers that have windings encased in epoxy resin. These encased windings make the installation process easier, as they are dry and they do not require cooling oil.
- A cast-resin transformer is not required to be kept in a fire-proof vault. The layer of epoxy protects it from dust and corrosion. These transformers are used in a wide variety of applications and they can be installed indoors or outdoors.
- Cast-resin transformer are commonly used in industrial, utility, and commercial applications. Transformer products provided by manufacturers are weather protected with the help of NEMA 3R outdoor enclosures. They are designed in such a way that they can be used outdoor applications, where weatherproofing is required, and mounted onto a skid frame.
Various Benefits Offered by Cast-resin Transformers to Drive Global Market
- Advantages of cast-resin transformers over the old-style oil-filled transformers are quite apparent. One of these benefits is minimal fire risk. Materials used for production of cast-resin transformers are hardly inflammable and they can be described as self-extinguishing. Hence, there exists no need to use any special fire protection coatings for cast-resin transformers. Furthermore, in case of fire, the emission of toxic gases and opaque fumes is very low.
- These advantages make cast-resin transformers a perfect choice for installation at places where safety is crucial, such as hospitals, public premises, airports, subway lines, mines, oil rigs, nuclear power plants, and ships
- No cooling liquids are required, as cast-resin transformers need only air for cooling. Hence, they are nearly maintenance free, whereas a liquid-cooled transformer requires much more attention. This makes cast-resin transformers eco-friendly, as no liquid coolants of whichever chemical composition are released into the environment.
