How to prepare an oil-immersed transformer specification
Distribution and power transformer quotations require more than voltage and capacity. Cooling arrangement, tapping method, insulation levels, loss requirements, accessories, environmental conditions, transportation limits and testing requirements all affect the final design.
Electrical and mechanical data
- Rated capacity, frequency and voltage ratio
- Vector group, impedance and insulation level
- On-load or off-circuit tap-changing requirement
- No-load and load-loss targets
- Short-circuit, sound and temperature-rise requirements
Cooling, accessories and site data
- Cooling method and radiator arrangement
- Conservator or fully sealed tank preference
- Protection, monitoring and bushing requirements
- Altitude, ambient temperature, pollution and corrosion environment
- Testing, documentation, transport limits and destination
Which voltage classes are available?
The current product range includes distribution units and project configurations for 35kV, 110kV and 220kV systems. Final ratings and standards are confirmed for each project.
Are oil-immersed transformers supplied by the same factory as the insulation materials?
No. Complete oil-immersed transformers are coordinated through qualified project-specific transformer manufacturing partners.
