SGB11-R Dry-Type Transformer - H Class (180°C), Non-encapsulated, For High-Rise & Data Centers
A revolutionary composite cross-sectional shape is utilized for the magnetic circuit structure of the SGB11-R H Class Transformer which maximises the electrical efficiency in relation to the magnetic flux circuit of the transformer due to the reduction in eddy current losses, resulting in up to 80% lower no-load currents compared to the national standard. As the construction and design of the transformer allow for improved energy efficiency, this translates into energy savings over time and has far-reaching benefits environmentally as well as economically.
An additional major benefit of the SGB11-R H Class Transformer can be found in its non-encapsulated coils. Traditional encapsulated coil designs trap heat and reduce the cooling capabilities of the coil; however, the non-encapsulated design allows for optimum heat dissipation and keeps the coils cool. Furthermore, the dry-type construction does not carry the hazards associated with the use of oil-filled transformers (e.g., fire and contamination), making the SGB11-R H Class Transformer ideal for high-stress and sensitive applications.

The H-Class insulation of the SGB11-R represents the highest level of operational safety for this class of transformer. H-Class insulated materials have the ability to operate at higher temperatures (up to 180 degrees Celsius) and have the ability to withstand extreme operating conditions. This characteristic is especially important for high-rise buildings and nuclear power plants; the operational stability of electrical supply equipment is vital to overall safety and continued operations in these environments. The H-Class insulation of the SGB11-R continues to provide reliable performance under severe operating conditions, making the SGB11-R an increasingly preferred choice for the growing number of critical infrastructure projects being developed worldwide.
To summarize, the H Class Non-Encapsulated Coil Dry-Type Power Transformer (SGB11-R) is the most technically advanced power transformer currently available on the market. Not only does the SGB11-R provide a substantial reduction in no-load current, thus improving operational efficiency and energy savings, but also the SGB11-R's non-encapsulated design provides improved cooling, reliability, and H-Class insulation properties allow for installation in the most demanding applications such as high-rise buildings and nuclear power plants. The SGB11-R provides a superior level of performance, reliability, and effectiveness for current and future energy needs of the global marketplace. Invest in the SGB11-R to establish 1st-rate performance and protection, propelling your energy transformation projects forward toward a sustainable and reliable future.
