Features

1. The coil adopts a low axial short-circuit force structure. When the transformer is short-circuited, it can greatly reduce the axial short-circuit force and greatly improve the ability of withstanding short-circuit.

2. All the bolts and nuts on the cover surface are made of 304 stainless steel, which enhances the rust prevention ability of the transformer.

3. Each sealing rubber ring adopts the best rubber material in China, which greatly prolongs the service life of the sealing rubber ring.

4. The transformer body adopts a high-reliability support structure to ensure reliable compression of the upper and lower parts of the coil. The entire body structure improves the ability of withstanding short-circuited.

5. This not only reduces the no-load loss of the transformer, but also ensures that the core flux is not saturated when the transformer is operating under voltage, so that the third harmonic of the transformer is small.

1. Ultra-low energy loss:

As shown in Chart 1, the S13 series reduces no-load loss by about 53% compared with the S9 model and 26% compared with the S11 model, and load loss is also reduced by more than 6% compared with the S11 model. The ultra-low loss design directly cuts down on long-term power consumption, lowering electricity costs for users and reducing carbon emissions for power systems.

2. High-quality silicon steel core:

S11 S13 1000kVA Oil Immersed Transformer uses cold-rolled grain-oriented silicon steel sheets with high magnetic permeability and low iron loss as the core material. The core is processed with advanced step-lap stacking technology, which minimizes magnetic leakage and core vibration, further reducing no-load loss and operating noise (the operating noise is controlled within 50dB, far lower than the national standard of 65dB).

3. Optimized insulating and cooling system:

The transformer uses high-grade mineral insulating oil with good thermal stability and insulation performance, matching a sealed corrugated oil tank structure. The corrugated tank can automatically expand and contract with the temperature change of the insulating oil, realizing sealed maintenance-free operation (service life of the sealing system is over 20 years). The optimized oil circuit design accelerates heat dissipation, ensuring stable operation even at full load for a long time in high-temperature environments.

4. Strong structural robustness:

The tank and frame are made of high-quality cold-rolled steel plate with anti-corrosion coating (epoxy zinc-rich primer + polyester finish), which has excellent resistance to rust, moisture, and mechanical impact. It can adapt to harsh outdoor working environments such as coastal high-humidity areas, industrial park dust areas, and northern low-temperature areas (-40℃ to 60℃ operating temperature range).

5. Intelligent monitoring compatibility:

The S11 S13 1000kVA Oil Immersed Transformer is reserved with installation interfaces for intelligent monitoring devices (such as oil temperature sensor, winding temperature sensor, and partial discharge monitor). It can be connected to the power grid intelligent management system to realize real-time monitoring of oil temperature, winding temperature, oil level, and operating status, and send an alarm in time for abnormal conditions, improving the safety and intelligence of operation.

Key application scenarios

The design of S11 S13 1000kVA Oil Immersed Transformers is highly versatile, featuring high efficiency, stability, and environmental adaptability, making it suitable for various power distribution scenarios, including:

1.Industrial parks and heavy industrial enterprises

For heavy industrial enterprises with large power loads and requiring long-term continuous operation, such as steel, chemical, and mechanical manufacturing industries, S13 1000kVA Oil Immersed Transformer is an ideal power distribution equipment. Its ultra-low loss can reduce production energy consumption costs, and its sturdy structure can adapt to the complex power environment of industrial sites.

2.Urban and rural power grids

As a core equipment for the national energy-saving power grid transformation and upgrading, it is widely used in urban residential communities, rural power supply stations, and municipal public facilities. Its low-noise design meets the environmental requirements of residential areas, and its energy-saving performance conforms to the national "dual carbon" strategy.

3.Power plants and substations

S11 S13 1000kVA Oil Immersed Transformer is used as a distribution transformer for thermal power plants, hydropower plants, and wind power plants, meeting the power transmission needs of medium and low-voltage power grids. Its high efficiency improves the overall power transmission efficiency of power plants. For large infrastructure projects with high requirements for power supply reliability, such as high-speed railways, highway service areas, and airport logistics parks, the S13 series can provide stable and continuous power supply, and its sealed structure also reduces the workload of on-site maintenance.
