Recently, the Ministry of Industry and Information Technology released the public notice of Green Factories and Green Industrial Parks (2025).

Three enterprises in Tongshan District have been shortlisted as Green Factories, including Jiangsu Subian Power Equipment Co., Ltd.

When Yemeni customers seek stable and reliable Chinese transformer manufacturers for power grid construction and infrastructure projects, they often have concerns. However, on-site visits to Jiangsu Subian Power's factory can usually dispel all their worries. These face-to-face visits, with our professional service team providing introductions, allow buyers to directly verify the manufacturer's production strength, product quality, and service capabilities—a key factor in making confident decisions when purchasing transformers in bulk. Why has Subian Power become a trusted choice in Yemen and many other parts of the world's power sector? Let me explain our three key strengths.

Yemen's power grid construction and infrastructure are currently undergoing rapid development, making the selection of a reputable transformer manufacturer crucial to the success of any project. As a veteran in the power equipment industry,  Subian  Transformer Power recently hosted a group of important Yemeni clients, inviting them to visit our modern factory. The core purpose of this visit was to directly address the clients' key needs, showcase our technical strength and service guarantees, and further solidify our cooperative trust.

Against the backdrop of deepened energy cooperation under the "Belt and Road" Initiative, a delegation from Ethiopian National Electric Power Corporation visited Subian Power, conducting in-depth negotiations focusing on the technological innovation and project implementation of oil-immersed transformers. This meeting closely aligns with Ethiopia's power grid upgrading needs, centering on high-efficiency and energy-saving oil-immersed transformer products to jointly depict a new blueprint for China-Ethiopian power interconnection.

Which dry-type transformer stands out for durability? Subian Power has the answer! With years of deep expertise in the industry, it sets extremely high standards for material selection – focusing on high-conductivity red copper as the core material, with a 99.9% conductivity standard plus multiple strict inspections. Any substandard material is directly rejected, ensuring every piece of equipment is inherently "high-efficiency".

Recently, Jiangsu Subian Power Equipment Co., Ltd. showcased its core transformer products at the "Electrical Networks of Russia-2025" exhibition in Moscow, reaping substantial gains at this top-tier Eastern European power industry event.

Subian Power received Venezuelan clients for a 2-day in-depth technical collaboration, focusing on three core product categories: American-style transformers, underground transformers, and dry-type transformers. The company customized solutions with professional expertise, centered on the clients' power consumption needs, demonstrating its technical strength and service philosophy.

This article focuses on common faults of power transformers such as overheating, abnormal noise and oil leakage, detailing scientific troubleshooting processes and practical methods to help operators quickly locate problems and ensure stable power grid operation.

The cooling method of a main transformer is crucial to ensuring its stable operation. Common types have their own characteristics, and Subian Electric has performed prominently in dry-type transformer cooling technology, providing reliable solutions for the industry.
