Our 10 MVA oil transformer is a state - of - the - art electrical device designed to meet the diverse power distribution needs. With a capacity of 10 MVA (10000kVA), this oil - type transformer is a reliable workhorse in the power grid.
The 10 MVA oil transformer operates at a primary voltage of 23kV and a secondary voltage of 13,860V. Its connection group is Ynd11, which is a well - established and widely used configuration in the power industry. This connection group offers several advantages, such as providing a neutral point on the low - voltage side for single - phase loads and better protection against unbalanced loads.
One of the remarkable features of this 10 MVA oil transformer is its dual - frequency operation capability. It can operate at both 50Hz and 60Hz frequencies, making it highly adaptable to different power systems around the world. Whether you are in a region with a 50Hz power grid or a 60Hz one, this 10 MVA oil transformer will perform efficiently.
The oil - type design of the 10 MVA oil transformer is a key factor in its performance. The insulating oil not only provides excellent electrical insulation but also helps in dissipating heat generated during operation. This ensures that the transformer can run continuously without overheating, thereby extending its service life.
SCBH15 Amorphous Alloy Dry-type Transformer
The SCBH15 amorphous alloy dry-type transformer is an advanced electrical device that combines the latest technological advancements with high - performance materials to provide efficient and reliable power transformation solutions. This product is designed in strict accordance with the IEC (International Electrotechnical Commission) standards, ensuring its quality and compatibility on a global scale.
1. Core Features
- Amorphous Alloy Core: The most prominent feature of the SCBH15 transformer is its use of amorphous alloy material in the core. Amorphous alloy has extremely low hysteresis loss and eddy - current loss compared to traditional silicon steel cores. This results in significantly reduced no - load losses, making the transformer highly energy - efficient. It is like a thrifty steward, conserving energy and reducing operational costs over its long service life.
- Dry - type Design: The dry - type design eliminates the need for oil, which not only enhances safety by eliminating the risk of oil leakage and fire but also makes it environmentally friendly. It can be installed in a wide range of locations, including indoor spaces, due to its non - flammable and non - polluting nature. It is as safe as a fortress, protecting both people and the environment.
2. Performance Advantages
- High Efficiency: With its advanced core material and optimized design, the SCBH15 transformer achieves high levels of efficiency. It can convert electrical energy with minimal losses, ensuring that more power is delivered to the load. This efficiency is like a well - tuned engine, running smoothly and effectively.
- Low Noise Operation: The unique structure and high - quality materials used in the transformer contribute to its low - noise operation. This is especially important in environments where noise pollution needs to be minimized, such as hospitals, schools, and residential areas. It operates as quietly as a gentle breeze, causing no disturbance.
- Good Thermal Performance: The transformer is equipped with an effective cooling system that can dissipate heat quickly. This allows it to operate stably under various load conditions, ensuring a long service life. It is like a well - ventilated room, keeping the internal components at a proper temperature.
