Oil Immersed Distribution Transformer

Product Description:

1. Strong adaptability: It has high temperature resistance and overload capacity, and can operate stably for a long time in harsh environments such as high temperature and high load rate.
2. Exquisite appearance: The product has undergone comprehensive polishing and rust removal treatment, using powder electric spraying technology and equipped with a wide sheet heat sink to ensure that the coating is long-lasting and does not fade.
3. Leak free design: The sealing element is made of acrylic material, and one-time molding technology ensures that the product will never leak. The equipment undergoes positive and negative pressure leak testing before leaving the factory, ensuring reliable quality.
4. Safety and environmental protection design: The materials and processes fully comply with safety and environmental protection requirements, do not release toxic gases, have low smoke concentration during combustion, are non corrosive, and ensure that the equipment is environmentally friendly.

Product features:

1. Low loss design: Adopting a new type of iron core and optimized winding structure design, the no-load loss of traditional transformers is reduced by more than 20%, and the load loss is reduced by more than 10%, significantly improving energy efficiency.
2. Low noise operation: Using high-quality silicon steel sheets and optimized magnetic circuit design, the noise level is significantly reduced, meeting the environmental requirements of modern cities and residential areas.
3. High reliability: The winding and body are carefully designed to have strong short-circuit resistance. Using high-quality insulation materials and high-temperature resistant transformer oil to ensure safe operation and extended lifespan.
4. Environmental protection and energy conservation: The insulation oil adopts pollution-free and recyclable environmentally friendly insulation oil. The product materials are recyclable, with excellent sealing performance, no leakage, and maintenance free.
5. Strict quality inspection: Transformers must undergo rigorous testing in accordance with national standards GB6450-1986 and IEC 60076 before leaving the factory, including multiple key items such as partial discharge, lightning impulse, noise, etc., to ensure the high quality and reliability of the product.

Our technological advantages:

1. Shanghai Zhiyou International's leading R&D technology cloud platform

Integrating electromagnetic optimization design, parametric drawing, performance analysis and structural optimization, automatic drawing, and other functions of transformers to achieve resource sharing in transformer design, as well as searching, modifying, and version control of various data information.

2. Simulation analysis

The current field, temperature field, electric field, leakage magnetic field, wave process, and short-circuit force of transformers. The research and design of each series of products are carried out through simulation analysis of flow and temperature fields to determine the average temperature rise of the coil and the hot spot temperature seat, ensuring product performance.

3. Smart operation and maintenance platform

By collecting key data such as temperature, current, voltage, vibration, and grid harmonics of transformers, online power quality analysis, fault alarms, and installation on mobile phones can be achieved.
