China's Transformer Exports Hit US$2.5 Billion in Q1 2026
On May 5, China's General Administration of Customs (GACC) released Q1 2026 trade data: power transformer exports hit USD 2.50 billion, surging 37.8% year-over-year; high-voltage switchgear exports reached USD 1.42 billion, up 21.4% YoY, signaling sustained demand in global electrical infrastructure markets.
Why Overseas Grids Need Chinese Power Equipment?
Industry analysts attribute the spike to accelerating global grid modernization and renewable energy integration, driving strong procurement of IEC-compliant high-voltage transformers and switchgear. This creates durable export tailwinds for Chinese OEMs supplying transmission and distribution (T&D) infrastructure worldwide
Who is Ningbo Tianan and what overseas orders has it secured?
With over 50 years of deep commitment to the power industry, Ningbo Tianan has built profound R&D and manufacturing expertise in transformers and high-voltage switchgear. Since the beginning of 2026, the company has won EPC-grade export contracts in the Philippines, Rwanda, and Kenya, with phased delivery now underway.
What transformer products does Ningbo Tianan supply?
Backed by years of hands-on overseas project delivery experience, Ningbo Tianan can reliably supply a full range of transformers across all voltage levels, fully adaptable to diverse power transmission and distribution scenarios. The product portfolio primarily covers three major voltage classes: 110 kV, 35 kV, and 10 kV, strictly complying with the IEC 60076 international standard. Rated capacity, connection group, loss parameters, and impedance values can all be customized to meet specific project conditions. Typical technical parameters for each voltage level are provided below for reference:
