SYHF Commences Production of S-M-630kVA10(6)-0.4 Oil Immersed Transformers with Rigorous Testing Protocols

SYHF (Jiangsu) Electric Co., Ltd. is pleased to announce that we are now in the production for its latest batch of S-M-630kVA10(6)-0.4 Oil Immersed Transformers at the company’s modern manufacturing base in Pizhou City, Jiangsu Province. This new production run reflects the continued strong demand for SYHF’s reliable and energy-efficient power equipment, serving both domestic and international clients.

The S-M-630kVA10(6)-0.4 Oil Immersed Transformer is a three-phase, oil-immersed distribution transformer with a rated capacity of 630kVA. Engineered with advanced magnetic core materials and optimized winding structures, this model delivers low no-load losses, high overload capacity, and exceptional operational stability—making it ideal for urban distribution networks, industrial parks, and rural electrification projects.

At the heart of this production phase lies SYHF’s unwavering commitment to quality. Each S-M-630kVA10(6)-0.4 Oil Immersed Transformer undergoes a comprehensive series of testing and inspection procedures throughout the manufacturing process. From raw material verification to core assembly, winding, tank sealing, and final oil filling, every step is monitored by experienced technicians using state-of-the-art testing equipment. Key tests include ratio and polarity checks, winding resistance measurement, no-load and load loss evaluation, dielectric withstand voltage testing, and partial discharge monitoring. In addition, strict leakage and sound-level tests are performed to ensure that every unit meets both international standards and customer-specific requirements.

“Our production line is currently operating at high efficiency to fulfill scheduled orders, and we have placed extra emphasis on the testing phase to guarantee that every transformer leaving our workshop performs flawlessly in the field,” said a senior production manager at SYHF. “With over 20,000 square meters of dedicated workshop space and a well-equipped quality control laboratory, we are able to conduct rigorous inspections at every milestone, ensuring that the S-M-630kVA10(6)-0.4 Oil Immersed Transformer bearing the SYHF brand delivers the durability and efficiency our customers expect.”

SYHF, founded in 2024, has rapidly built a reputation for excellence in the design and manufacture of transformers and high/low voltage distribution equipment. The company’s sprawling 50,000-square-meter facility, combined with its experienced R&D team and customer-centric service model, enables it to provide tailored solutions for diverse power system needs.

As production progresses, SYHF remains dedicated to maintaining the highest quality standards. The ongoing testing and inspection regimen not only ensures compliance with all relevant safety and performance norms but also reinforces the company’s promise of reliability—one that will continue to define every S-M-630kVA10(6)-0.4 Oil Immersed Transformer produced under the SYHF name.
