Hengfengyou Electric SFZ12-6300KVA-115kv/11kV main transformer helps Uzbekistan: decoding the core requirements of power grid upgrade

Under the wave of energy interconnectivity in Central Asia, Uzbekistan is accelerating the modernization of its power grid. Recently, three SFZ12-6300KVA-115kv/11kV main transformers independently developed, designed, and produced by Hengfengyou Electric have successfully passed acceptance and been officially delivered to the Uzbekistan State Grid. This power equipment, which gathers China's high-end equipment manufacturing technology, not only injects new momentum into the power consumption of local industry and people's livelihood, but also becomes another benchmark case of the "the Belt and Road" energy cooperation.

I、 Hengfengyou Electric SFZ12-6300KV-115KV/11KV main transformer landed in Uzbekistan: why it?

As the most populous country in Central Asia, Uzbekistan's industrial and agricultural electricity consumption has continued to rise in recent years, and the problems of aging power grid equipment and insufficient power supply reliability have become increasingly prominent. Especially the power transmission bottleneck between the southern industrial clusters and the northern agricultural production areas urgently requires efficient and stable transmission and distribution equipment support.

 

The three SFZ12-6300KVA-115kv/11kV main transformers delivered by Hengfengyou Electric accurately match the core requirements of the Wuguo power grid for "capacity expansion, loss reduction, and efficiency improvement": their 115kV high-voltage side can be directly connected to the national main power grid, while their 11kV low-voltage side can flexibly adapt to regional distribution networks, balancing long-distance transmission and large capacity distribution; At the same time, in response to the climate characteristics of high temperatures in summer (some areas exceeding 45 ℃) and dry and dusty winters in Ukraine, the equipment has strengthened its heat dissipation design and dust sealing technology to ensure long-term stable operation in extreme environments - this is the key reason why Ukraine chose it.

II、 Hengfengyou Electric SFZ12-6300KVA-115kv/11kV main transformer technology hardcore: three major innovative breakthroughs revealed

As a customized main transformer serving the Central Asian power grid, the technical team of Hengfengyou Electric has focused on the three core values of "efficiency, intelligence, and reliability" during the research and development stage, achieving multiple key technological breakthroughs:

Low loss and energy-saving design: using a new type of low loss CRGO iron core material, combined with optimized winding structure, the no-load loss is reduced by 15% compared to traditional products, and the load loss is reduced by 8%. It can save about 120000 kWh of electricity per year for the Ukrainian power grid, equivalent to reducing 100 tons of carbon dioxide emissions;

Strong short-circuit resistance capability: Through simulation software to simulate extreme short-circuit conditions, the optimizer body support structure and winding compression process have been optimized. After third-party testing, the equipment can withstand a short-circuit current impact of 40kA/2s, far exceeding the standard requirement of 16KA for the Wuguo power grid;

SCADA system: equipped with SCADA system produced by China NARI Group, to achieve remote monitoring of transformers and ensure residential electricity supply.

III、 Hengfengyou Electric SFZ12-6300KVA-115kv/11kV main transformer landing record: Chinese craftsmanship from drawings to delivery

To ensure that the equipment is fully compatible with the Uzbekistan power grid environment, Hengfengyou Electric has established a dual track team of "technology+service" to fully participate in the project implementation:

Deep docking of requirements: In the early stage, a technical team was sent to conduct on-site inspections in Ukraine to communicate with local power engineers and operation and maintenance teams, and identified 12 core requirements, including "adaptability to high temperature and high dust environments" and "localized spare parts support";

Production full process control: from silicon steel sheet selection, insulation material testing to overall assembly and debugging, every process is certified according to ISO 9001, IEC, GOST standards;

Delivery and Training: Before the equipment leaves the factory, Hengfengyou Electric provides customers with a 10 day operation training, covering daily inspections, troubleshooting, and other content to ensure a smooth transition - this is the best footnote of "Chinese craftsmanship".

IV、 Hengfengyou Electric SFZ12-6300KVA-115kv/11kV Main Transformer: Technological Empowerment for a New Milestone in China Ukraine Energy Cooperation

Summer, Sales Director of Hengfengyou（ summer@hengfengyou.com ）The operation of these three SFZ12-6300KVA-115kv/11k main transformers is not only an important achievement of Hengfengyou Electric's "going global" strategy, but also reflects the deepening of energy cooperation between China and Ukraine

Assisting Ukraine's energy independence: After the equipment is put into operation, the power supply reliability in the southern industrial zone of Ukraine has been improved to 99.9%, and the annual power outage time has been reduced by about 50 hours, providing stable power guarantee for local pillar industries such as textiles and chemicals;

Promote mutual recognition of technical standards: the experience accumulated in the project, such as "Central Asia Climate Adaptability Design" and "Smart Transformer Operation and Maintenance", has been included in the overseas product standard library of Hengfengyou Electric, and will be applied to more countries along the "the Belt and Road" in the future;

Deepening production capacity cooperation between China and Ukraine: Hengfengyou Electric has signed a follow-up cooperation agreement with the Ministry of Electricity of Ukraine, planning to establish a transformer assembly center in the local area, drive component exports and technical training, and help improve Ukraine's high-end equipment manufacturing capabilities - this is the global value of "Made in China".

V、 Conclusion: Hengfengyou Electric SFZ12-6300KVA-115kv/11kv main transformer - the "global guardian" of high-end equipment in China

From the SFZ12-6300KVA-115kv/11kV main transformer in Uzbekistan, to the offshore wind power transformer in Southeast Asia, and to the photovoltaic booster station equipment in Africa, Hengfengyou Electric has always been committed to "technological innovation+localized services" to promote China's high-end equipment to the world. This main transformer across mountains and seas not only bears the temperature of power energy, but also marks a new chapter of "China's smart manufacturing" and "the the Belt and Road" resonance at the same frequency. In the future, with the acceleration of global energy transformation, Hengfengyou Electric will continue to deepen its technological research and development, providing safe, efficient, and green power solutions for more countries.
