Product Description:
- The installation and use environment is relatively harsh, with high requirements for three defenses.
- Strong overload capacity and good ability to withstand thermal shock.
- Strong ability to withstand harmonics.
- Low self loss and high efficiency.
- The high and low voltage incoming and outgoing lines have different methods and compact structures.
- There are various types of requirements for capacity, voltage, and impedance.
Product features:
- Low loss: The no-load loss is 20% lower than the national standard, and the load loss is 10% lower. Meet national energy efficiency requirements.
- Low noise, low partial discharge: The average noise level is 10dB lower than the national standard, and the partial discharge is less than 5pC.
- Strong "three prevention" ability: moisture-proof, anti salt spray, and anti mold. Can operate normally at 98% humidity. After shutdown, it can be put into operation without pre drying, reducing maintenance time and costs.
- Three characteristic tests: The product has passed F1, C2, E2 level combustion, environmental, and thermal shock tests, is flame retardant and fire-resistant, and can be directly installed in the load center.
- Strong overload capacity: using H-grade (180 ℃) insulation material and designed for F-grade temperature rise (100K). The insulation system has a large margin and strong overload capacity.
- The protection system is sensitive and reliable: equipped with a temperature control protection system for three-phase inspection, which can be remotely monitored. Equipped with a forced air cooling system, it can meet special environmental requirements.
- Strict quality inspection: Transformers must undergo strict 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:
- 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.
- 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.
- 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.
