35kV Power Transformers
35kV-class power transformers with a rugged frame structure — the SZ13-20000/35 prototype passed the sudden short-circuit test of the National Transformer Quality Inspection Center in one go.
110kV Power Transformers
110kV-class energy-saving power transformers: low loss, low temperature rise, no core lifting and zero leakage at a leading domestic performance level.
40 MVA Power Transformers (110kV Class)
The 40000kVA rating of the 110kV-class series covering 6300–80000kVA for regional grids and industrial park main transformers.
63 MVA Power Transformers (110kV Class)
The 110kV-class SZ20-63000/115 on-load-tap-changer power transformer — the workhorse rating for power plants, substations and renewable step-up stations.
