S13 1000KVA 10/0.4KV Oil - Immersed Transformer
The S13 1000KVA 10/0.4KV oil - immersed transformer is a high - quality electrical device designed to efficiently transform electrical energy between different voltage levels. This type of transformer, with the key features of 1000KV oil type transformer, is widely used in various power distribution systems due to its reliability and performance.
1. Design and Structure
- Core: The core of the S13 1000KVA 10/0.4KV oil - immersed transformer is made of high - quality cold - rolled grain - oriented silicon steel sheets. These sheets are carefully laminated to reduce eddy current losses, like building a solid and efficient energy - conversion foundation. The core is designed with an optimized cross - sectional area to ensure a low magnetic flux density, which in turn minimizes core losses and improves the overall efficiency of the transformer.
- Windings: There are two sets of windings, the primary winding and the secondary winding. The primary winding is designed for a voltage of 10KV, while the secondary winding is for 0.4KV. The windings are made of high - purity copper or aluminum conductors. Copper windings offer excellent electrical conductivity and thermal performance, similar to a super - highway for electric current, ensuring smooth and efficient power transfer. The windings are carefully insulated with high - quality insulating materials to prevent short - circuits and ensure long - term operation.
- Oil Tank: The transformer is immersed in high - quality insulating oil inside an oil tank. The oil serves multiple purposes. It acts as an insulator, preventing electrical breakdown between different parts of the transformer. It also acts as a coolant, carrying away the heat generated during the operation of the transformer, just like a cooling river that keeps the device in a stable working state. The oil tank is designed with a hermetic structure to prevent moisture and oxygen from entering, which could degrade the performance of the insulating oil and the transformer.

3. Performance Advantages
- High Efficiency: The S13 series of 1000KVA 10/0.4KV oil - immersed transformers are designed with advanced technology to achieve high efficiency. The low core losses and optimized winding design result in less power loss during operation, saving energy and reducing operating costs. It's like a fuel - efficient car that can go a long way with less energy consumption.
- Good Voltage Regulation: The well - designed impedance of the transformer ensures good voltage regulation. When the load changes, the secondary voltage can be maintained within an acceptable range, providing a stable power supply for electrical equipment. This is crucial for the normal operation of various electrical devices, from small household appliances to large industrial machinery.
- Reliability: With its robust design and high - quality components, the S13 1000KVA 10/0.4KV oil - immersed transformer offers high reliability. The hermetic oil tank and high - quality insulating materials protect the internal components from environmental factors such as moisture, dust, and chemical corrosion. It can operate stably for a long time under various harsh conditions, like a tough warrior in the power - distribution battlefield.
4. Application Scope
The S13 1000KVA 10/0.4KV oil - immersed transformer, as a typical 1000KV oil type transformer, is suitable for a wide range of applications. It can be used in industrial power distribution systems to supply power to factories, workshops, and industrial equipment. In commercial buildings, it provides power for offices, shopping malls, and hotels. It is also commonly used in rural power grids to improve the power supply quality in rural areas.
In conclusion, the S13 1000KVA 10/0.4KV oil - immersed transformer, with the characteristics of 1000KV oil type transformer, is a high - performance and reliable electrical device that plays a vital role in power distribution systems. Its advanced design, excellent technical parameters, and wide application scope make it a popular choice in the power industry.
