S13 2000KVA 10/0.4KV Oil - Immersed Transformer The S13 2000KVA 10/0.4KV oil - immersed transformer is a high - performance electrical device designed to meet the diverse power distribution needs. This oil transformer combines advanced technology and reliable design, making it an ideal choice for various industrial and commercial applications. I. Design Features Core Design The core of the S13 oil transformer is made of high - quality cold - rolled grain - oriented silicon steel sheets. These sheets are precisely cut and assembled to minimize magnetic leakage and reduce core losses. The stepped core design not only enhances the magnetic circuit efficiency but also reduces the overall size of the transformer, making it more compact and space - saving. Winding Design The windings are made of high - purity copper or aluminum conductors. The primary winding is designed for a voltage of 10KV, while the secondary winding is for 0.4KV. The winding structure is carefully arranged to ensure uniform distribution of the electric field and current, which helps to improve the electrical performance and reduce the risk of short - circuits. The use of high - quality insulation materials between the windings provides excellent insulation performance, ensuring the safety and reliability of the transformer operation. Oil Tank Design The oil tank of this oil transformer is made of high - strength steel plates. It is designed to withstand the internal pressure generated during operation and protect the internal components from external environmental factors. The oil tank is equipped with an oil - conservator, which can compensate for the volume change of the insulating oil caused by temperature variations. The radiator fins on the surface of the oil tank increase the heat dissipation area, effectively reducing the temperature of the transformer during operation. III. Performance Advantages High Efficiency Thanks to its advanced core and winding design, the S13 2000KVA 10/0.4KV oil - immersed transformer has low no - load and load losses. This means that it can convert electrical energy more efficiently, reducing energy waste and saving operating costs for users. Reliability The use of high - quality materials and strict manufacturing processes ensures the high reliability of

Onan Knan Multipurpose Industrial Customized Liquid Immersed Distribution Transformer

Product Description ----Basic structure of oil-type transformer Distribution transformer is also known as a typical kind of isolation transformer. The main function of this transformer is to alter the high voltage to the normal voltage like 208V 380V and 415V to use in electric that can be used in industries, infrastructure and households. With the rise of decentralized generated electricity, they are now also responsible for supplying power to the grid. 1. The transformer body adopts a new insulation structure, which improves the short-circuit resistance. 2. The transformer core is made of high-quality cold-rolled silicon steel sheets with high magnetic conductivity. 3. The transformer core consists of high/low-voltage windings are selected high-quality oxygen-free copper wire, and multi-layer cylindrical structure. 4. All fasteners with special anti-loosening treatment. 5. The oil tank is corrugated structure, the cover and the edge of the box are completely welded or fastened with bolts in two types, which fundamentally prolongs the service life of the transformer oil and insulating materials. The above standards are subject to the latest released information; Equipment requirements should be based on the corresponding latest national professional standards. Detailed Photos ----Feature: ♦Good Economic Performance The NX series products are based on the S11 series, the no-load loss is reduced, and the no-load current is reduced compared with the S11 series. ♦Long Lasting The transformer oil tank adopts a fully sealed structure. The oil tank and the tank edge can be connected by bolts or welded to death. The transformer oil does not meet the air, which prolongs the service life. ♦High Operational Reliability The relevant parts of the fuel tank seal are improved to increase the reliability and improve the technological level to ensure the reliability of the seal. ♦Small Footprint S series transformer oil tank adopts corrugated plate radiator. When the oil temperature changes, the corrugated plate thermal expansion and contraction can replace the role of the oil conservator. The corrugated plate oil tank has a beautiful appearance and small footprint. ----After-sales service: Provide comprehensive pre-sales consulting and program design services.
