Exploring the disruptive advantages of Haiyifeng transformer's 3D wound core oil-immersed transformers in power distribution. As a national-level manufacturing single-item champion enterprise, Haiyifeng transformer's with its unique amorphous alloy 3D wound core and other energy-saving core technologies, provides power systems with superior cooling efficiency, stronger insulation protection, and sustainable energy transmission solutions.
In our previous overview, we discussed the basic types and properties of transformer oil. However, engineers and maintenance teams often face real-world challenges: Which oil is best for a tropical substation? How often should dielectric strength be tested? Can I top up a mineral‑oil transformer with ester oil? This article provides quantitative benchmarks, a decision framework, and hands‑on maintenance procedures to help you extend transformer life and avoid costly failures.
Morocco, as a major industrial hub in North Africa, has experienced rapid development in industries such as chemical, metallurgical, and food processing in recent years. Local factories generally face the challenge of power upgrading due to insufficient capacity of old equipment and poor adaptability of new equipment.
Haiyifeng Transformer recently delivered five 6300kv-35/10kV large power transformers to a key project in Kyrgyzstan. These equipment will be used for local power grid upgrading and renovation projects, significantly improving regional power supply capacity and energy efficiency, and meeting Kyrgyzstan's growing industrial electricity demand.
Haiyifeng Transformer Electric recently successfully shipped a batch of core power equipment to South Africa, including a high-performance 10MVA-66kV transformer along with matching current transformers, voltage transformers, and other auxiliary equipment. This batch of equipment will be applied to a substation upgrade project in a crucial province of South Africa, aiming to solve key issues of insufficient regional grid transmission capacity and poor voltage stability, thereby injecting robust and reliable power support into the development of local industry and commerce.
On February 12, 2026, Haiyifeng Transformer successfully completed the loading and dispatch of 19 customized transformers for a major power distribution project in South Africa at its Qingdao production base. Two 40HQ containers, packed with the robust engineering of "Made by Haiyifeng," have officially set sail. This delivery is more than just an export; it is a profound realization of Haiyifeng’s professional delivery capabilities and its unwavering commitment to international service.
