| Function named in the directory | First design input | Supply boundary to agree |
|---|---|---|
| Large-power step-up transformer | Required input/output voltage and power duty | Transformer and its protection/interface requirements |
| Voltage-stabilising power supply | Supply variation and acceptable output tolerance | Regulation system and controls |
| SZ11 oil-immersed on-load category | Tap range and adjustment duty | Tap-changing equipment and control interfaces |
| SCB10 cast transformer / dry enclosure | Installation conditions and terminal arrangement | Transformer alone or enclosure included |
The company introduction lists S9, S11, SCB10, SCB11, SBH15, SYB and SF families alongside power, step-up, furnace and mining equipment. The product directory separately names large-power step-up transformers, high-voltage power supplies and voltage-stabilising equipment. A step-up requirement describes a voltage-conversion task; a stabilising-supply requirement describes how output voltage must behave as the supply or load changes. State that function before asking for a model.
For a step-up project, provide input and output voltages, frequency, power rating and duty. For voltage regulation, provide the incoming-voltage variation and required output tolerance, and ask what control arrangement is proposed. The company’s general introduction mentions voltage classes of 6, 10, 35 and 110 kV and an individual capacity of 31,500 kVA. That general statement is not a configuration schedule for every product in the directory.
