The Dyn11 transformer is a three-phase transformer with a power rating of up to 10 MVA. It is designed for use in medium-voltage applications and is capable of withstanding high temperatures. It is also equipped with a built-in oil-cooling system, which helps to reduce the risk of overheating and ensures a longer lifespan. The Yyno transformer is a three-phase transformer with a power rating of up to 20 MVA. It is designed for use in high-voltage applications and is capable of withstanding extreme temperatures. It is also equipped with a built-in oil-cooling system, which helps to reduce the risk of overheating and ensures a longer lifespan. The YNd11 transformer is a three-phase transformer with a power rating of up to 30 MVA. It is designed for use in high-voltage applications and is capable of withstanding extreme temperatures. It is also equipped with a built-in oil-cooling system, which helps to reduce the risk of overheating and ensures a longer lifespan. All three of these transformers offer a number of benefits, including high efficiency, reliability, and long lifespans. The Dyn11 transformer is the most cost-effective option, while the Yyno and YNd11 transformers offer higher power ratings and greater temperature resistance. All three transformers are designed to meet the highest safety standards and are backed by a manufacturer’s warranty.

In conclusion, oil-cooled transformers from a Chinese manufacturer offer a number of benefits, including high efficiency, reliability, and long lifespans. The Dyn11, Yyno, and YNd11 transformers all offer different power ratings and temperature resistance, making them suitable for a variety of applications.
