Import 110kv Power Transformer — Buy in Bulk from Supplier in China

This 110kV power transformer from Yugong Machinery is engineered for high-voltage transmission and distribution networks, conforming to Chinese National Standard GB1094.1~2-1996 and the International Electrotechnical Commission's IEC76 series. The unit's core is constructed from quality cold-rolled grain-oriented silicon steel sheets with chamfered joints and no punched holes, a design that contributes to an average no-load loss that is 35% lower than the requirements of GB/T 6451-2008. The windings feature a zigzag directed oil flow system for even cooling, and the regulating winding is separate from the main high-voltage winding to improve short-circuit withstand capability.

The transformer's construction focuses on durability and operational stability. The core and coil assembly is fixed rigidly within the tank at six points to prevent displacement during transport. Tank walls are fabricated from single, wide steel plates pressed into a corrugated shape to increase mechanical strength and reduce vibration noise. A diaphragm membrane within the conservator prevents oil contact with air, slowing oil aging, while a flat plate-type radiator provides effective cooling. The entire surface receives shot-blasting pretreatment and a quality paint finish for a durable, glossy exterior.

This type of transformer is typically sourced by power utilities, industrial plants, and infrastructure contractors for grid projects requiring reliable 110kV voltage transformation. The product is supplied with components sourced from established sub-suppliers and is packaged in fumigation-compliant wooden cases for export. Specific trade terms, including the minimum order quantity, lead time, and exact pricing, should be confirmed directly with Yugong Machinery, as these details are not provided in the listing.

Yugong Machinery Co., Ltd. is located at No.1288 Luban South Road, Yugong Industries, Tengzhou 277500, Shandong, China. The supplier profile indicates an 'imported' tier status and a 'harbor' trust tier, though the current response rate is listed as 0.00%, meaning there is no recorded history of responding to buyer inquiries on this platform. The listing does not provide details on the company's establishment year, manufacturing scale, or specific certifications.

The product description details a transformer built with technologies introduced from abroad and based on the experiences of leading manufacturers. It claims the use of components from well-known sub-suppliers due to long-term partnerships. The listing states that winding manufacture and assembly occur in a totally closed clean department and that strict quality assurance rules are followed for all insulating parts. However, specific third-party audit reports, factory capacity figures, or export client lists are not provided in the available data.
