Variable Frequency Drives (VFD)
Applicable project types:
- Thermal power generation
- Steel & metallurgy (including related industrial processes)
- Municipal water supply
- Industrial equipment drives
Typical loads:feed pumps / circulating water pumps / condensate pumps / ash & slag pumps / water intake pumps; forced-draft & induced-draft fans / main exhaust fans / dust removal fans / booster fans; boiler feedwater pumps, etc.
As per project specification.
Product capability (VFD + special power supplies / four-quadrant, etc.):
- Low-voltage VFD / high-voltage VFD / four-quadrant VFD, special power supplies, soft starters (listed in business scope).
- Power coverage: 0.75–500 kW (low-voltage coverage) and 90–5000 kW (as described for specific series/high-voltage scope).
- Input voltage: AC380–440V and AC400–690V (by series).
- Capacity ranges:
— Air-cooled: 250 kVA–15000 kVA
— Water-cooled: 6000 kVA–40000 kVA
- Key control/performance statements: speed accuracy up to 0.02%; voltage waveform quality THDu ≤ 3% (as stated).
Engineering & lifecycle service: upgrade & transformation, on-site installation & commissioning, training & acceptance; emphasizes that upgrade projects generally do not require civil works or DCS modifications and can be completed during maintenance outage.
Track record across multiple international projects. Subject to project-specific approval by the owner, engineer, or consultant.
