When Your Transformer Doesn’t Fit the Ship: A Real Lesson in Large Equipment Export Logistics from China
A real account of what happened when the allocated vessel space at Shanghai Port could not accommodate an 8,000 kVA 120kV OLTC transformer main tank during export to a DR Congo power station project — the rerouting to Lianyungang Port, the two-and-a-half-month delay, and the practical lessons learned. Written for international buyers and EPC procurement teams planning to source large power transformers from China. Includes recommendations on vessel space booking, port selection for heavy-lift cargo, nitrogen transport verification, and split shipment planning.
8000kVA 120kV OLTC Power Transformer Exported to DR Congo — Full Project Case Study
Zhongxin General exported a SZ13-8000/120 on-load tap-changing power transformer — 8,000 kVA, 120kV class, 27.8 tonnes total weight — to a power station project in the Democratic Republic of Congo. Independent quality inspection was personally overseen by a former General Manager of Chint Electric’s transformer division. The shipment navigated a real-world logistics challenge when vessel space constraints at the original port required rerouting via Lianyungang. The unit arrived at Mtwara Port, Tanzania on February 4, 2026, with package condition verified as no damage. Switchgear supplied as part of the complete package.
