S13 500KVA 10/0.4KV Oil - Immersed Transformer 1. Introduction The S13 500KVA 10/0.4KV oil - immersed transformer is a high - quality power equipment, designed to efficiently convert electrical energy between different voltage levels. With the development of the power industry, 500KVA power transformers like this one play a crucial role in ensuring a stable and reliable power supply for various applications, from industrial plants to commercial buildings. 2. Design and Structure This transformer adopts an oil - immersed design. The core is made of high - quality cold - rolled grain - oriented silicon steel sheets, which are stacked in a precise manner to reduce magnetic leakage and core losses. The windings are carefully wound with high - conductivity copper wires, ensuring low resistance and efficient power transfer. The transformer is placed in a sealed tank filled with insulating oil. The oil not only provides electrical insulation but also helps in dissipating heat generated during operation. 3. Technical Parameters (Referenced to National Standards) Parameter Specification Rated Capacity 500KVA High - Voltage Side Rated Voltage 10KV Low - Voltage Side Rated Voltage 0.4KV Frequency 50Hz Connection Group Dyn11 Impedance Voltage 4% - 6% 4. Performance Advantages High Efficiency: Thanks to its advanced design and high - quality materials, the S13 500KVA 10/0.4KV oil - immersed transformer has relatively low losses, which means more efficient power conversion. This can lead to significant energy savings over the long - term operation of the transformer. Reliability: The oil - immersed structure provides excellent insulation and heat dissipation, enhancing the reliability and service life of the transformer. It can withstand various environmental conditions and electrical stresses, ensuring a stable power supply. Safety: The transformer is equipped with multiple safety devices, such as temperature sensors, pressure relief valves, and oil - level indicators. These devices can monitor the operating status of the transformer in real - time and take corresponding protective measures in case of abnormal conditions. 5. Application Scenarios The 500KVA power transformer is suitable for a wide range of applications. In industrial settings, it can power

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.
