| Parameter | S11 Series | S13 Series | Explanation |
|---|---|---|---|
| Rated capacity |
From 30 kVA to 3150 kVA |
From 30 kVA to 3150 kVA |
The capacity of the transformer indicates how much power it can handle. |
| Voltage Class | From 10 kV to 35 kV |
From 10 kV to 35 kV |
The range of input and output voltage levels the transformer is designed for. |
| Frequency | 50/60 Hz | 50/60 Hz | The frequency of the alternating current the transformer operates with is typically aligned with regional power grid standards. |
| Efficiency | High efficiency | Very high efficiency |
Refers to the transformer's ability to convert electric power with minimal losses. The S13 series is generally more efficient than the S11. |
| Impulse Withstand |
High | High | The transformer's capability to withstand high voltage surges without damage protects against lightning strikes or other transient events. |
| Insulation Class |
Class F or Class H | Class F or Class H | The temperature rating of the insulation system allows for operation at higher temperatures thus extending service life. |
| Cooling | Natural cooling | Natural cooling | Describes the method of heat dissipation; natural oil cooling relies on convection. |
| Noise Level | Low | Very low | Measured in decibels (dB), indicates how much audible sound the transformer emits during operation. Lower values are preferable in quiet environments. |

Product Feature
- Impulse Withstand: These transformers are engineered to withstand high impulse voltages, making them suitable for environments prone to surges or transients, such as near lightning strikes.
- Advanced Cooling Capabilities: Oil-immersed transformers are naturally cooled, with the option for forced-oil cooling if required for higher power applications, ensuring efficient heat dissipation and maintaining stable operation even under heavy loads.
- High Efficiency: Both the S11 and S13 series prioritize energy conservation, featuring designs that minimize power losses, which leads to reduced operating costs and environmental impact. This is particularly evident in their no-load and load loss values.
- Enhanced Insulation Systems: With insulation classes typically up to Class F or Class H, these transformers can operate at higher temperatures, leading to improved longevity and reliability under prolonged use.
- Low Noise Levels: The design of the S11 and S13 series includes noise reduction measures, making them suitable for urban and residential areas where noise pollution is a concern.
Applications
- Substation Applications: These transformers are often used in substations as part of the step-up or step-down process, connecting power generation facilities to the distribution network.
- Commercial and Residential Power Distribution: The transformers’ combination of efficiency and low noise makes them ideal for supplying power to commercial buildings, shopping centers, and residential complexes.
- Renewable Energy Integration: As renewable energy sources like wind and solar become more prevalen
- Rural Electrification: The S11 and S13 series can be used in remote locations where reliable power distribution infrastructure is needed to support agricultural activities and rural development.
- Industrial Settings: Their robust construction and ability to handle varying loads make them suitable for industrial environments, including manufacturing plants and factories where consistent power quality is crucial.
