I. Hengfengyou Electric 25MVA-110kv/11kV main transformer: the "new engine of power" for China Kazakhstan energy cooperation
→ Project Background and Strategic Significance:
As an energy hub in Central Asia, Kazakhstan has faced the dual pressure of the surge of power grid load and the upgrading of old equipment in recent years. Hengfengyou Electric has precisely responded to this demand by building two 25MVA-110kv/11kv main transformers for it, which not only alleviates the power supply shortage of the local power grid, but also becomes a typical case of China Kazakhstan production capacity cooperation under the framework of the "the Belt and Road".
Product positioning and core values:
The two Hengfengyou Electric 25MVA-110kv/11kV main transformers delivered this time are positioned as "specialized equipment for upgrading the China Kazakhstan power grid", focusing on the three core values of "high stability, strong adaptability, and low loss". The goal is to help Kazakhstan achieve the dual transformation of "green grid" and "smart grid" through technological upgrades.
Market impact and customer recognition:
After the project was implemented, the State Grid Corporation of Kazakhstan highly praised the equipment performance, stating that it "provided key support for improving the reliability of the regional power grid". Hengfengyou Electric has further consolidated its brand influence in the Central Asian power equipment market, laying the foundation for future cooperation.
II. Customized design: "Kazakhstan adaptation solution" for Hengfengyou Electric's 25MVA-110kv/11kV main transformer
Climate adaptation optimization:
In some areas of Kazakhstan, the lowest temperature in winter can reach -40 ℃, and in summer, the high temperature exceeds 50 ℃, with frequent sandstorms. Hengfengyou Electric has made three improvements to these two 10MVA-110/10KV main transformers in response to this environmental characteristic: fully sealed structure to prevent wind and sand intrusion, weather resistant silicone rubber outer insulation material to resist UV aging, and wide temperature range oil chromatography analysis technology to ensure stable operation under extreme temperatures.
Breakthrough in energy efficiency improvement technology:
In order to meet Kazakhstan's "2030 Carbon Neutrality" goal, the main transformer adopts low loss silicon steel sheets and optimized winding technology, reducing no-load losses by 15% compared to traditional products. It can save about 120000 kWh of electricity per year for the local power grid, equivalent to reducing carbon dioxide emissions by 100 tons.
III. Full chain quality control: Hengfengyou Electric's "manufacturing hard power" of 25MVA-110kv/11kV main transformers
→ International standards and material traceability:
During the production process, Hengfengyou Electric strictly follows the international standards of ICE60076 and GOST-R for power transformers. The core materials are sourced from well-known Chinese suppliers, and a full traceability system of "material batch production process finished product performance" has been established to ensure that every 25MVA-110kv/11kV main transformer can be traced back to the source of raw materials.
→ Rigorous testing to verify reliability:
Before leaving the factory, the two main transformers need to pass 12 types of limit tests: including simulating short-circuit current 3 times (to verify short-circuit resistance), temperature rise test (continuous operation for 72 hours to monitor oil temperature), and lightning impulse test (simulating 100kA lightning wave impulse). During on-site acceptance by the Kazakhstan client, all parameters of the equipment exceeded the contract requirements.
IV. Industry benchmark effect: Insights from Hengfengyou Electric's 25MVA-110kv/11kV main transformer's "going global" strategy
From "manufacturing output" to "dual output of technology and services":
In this cooperation, Hengfengyou Electric not only exported products, but also provided a complete solution of "customized design+full chain quality control+localized services", providing a new paradigm of "technology premium" for Chinese electrical enterprises to "go global" - customers are willing to pay higher costs for "technology that meets their needs", rather than just focusing on low prices.
Sample of deepening energy cooperation between China and Kazakhstan:
Summer, Sales Director of Hengfengyou（ summer@hengfengyou.com ）Kazakhstan is the largest electricity market in Central Asia, and its power grid upgrade needs cover the entire process of power generation, transmission, and distribution. Through these two 25MVA-110kv/11kV main transformer projects, the company has successfully entered the local core equipment procurement list for power transmission and distribution, and is expected to participate in more substation renovation, new energy grid connection and other projects in the future, promoting the deepening of China Kazakhstan energy cooperation.
Conclusion:
Starting from the actual demand of Kazakhstan's power grid and the stable operation of two 25MVA-110kv/11kV main transformers, this cross mountain energy cooperation is not only a demonstration of the strength of "Made in China", but also a microcosm of the coordinated development of the global power industry. In the future, with the continuous investment of Hengfengyou Electric in technological innovation and service upgrading, its power equipment will certainly shine in more countries along the "the Belt and Road".
