Choose the transformer family
Oil-immersed units are commonly evaluated for outdoor utility and industrial distribution. Dry-type designs are often considered for indoor or fire-sensitive locations. Industrial isolation transformers address equipment isolation or special voltage conversion rather than ordinary distribution duty. Use the linked oil-immersed, dry-type and isolation category pages for detailed procurement questions and model-specific options.
Match the design to the application
A utility feeder, factory, mine, solar plant, wind project or charging site can place different demands on the transformer. Define the continuous and peak load, expected load growth, motor starting, harmonics, renewable generation and redundancy strategy. This information helps determine capacity, impedance, thermal margin and whether a standard distribution design or a special-purpose unit should be reviewed.
Provide the essential electrical data
Every RFQ should state rated capacity, primary and secondary voltage, frequency, phase, vector group, impedance, tap requirements and neutral arrangement. Buyers should also provide the single-line diagram, fault level where relevant and any limits on losses, noise or dimensions. A complete technical schedule reduces clarification cycles and allows product, drawing and test scope to be aligned from the beginning.
Account for the installation environment
Indoor and outdoor installations require different enclosure, cooling and maintenance decisions. High ambient temperature, dust, humidity, altitude, coastal exposure and restricted ventilation should be declared. African projects may need special attention to heat, dust and utility specifications, while North American projects require separate confirmation of frequency, efficiency scope and applicable local requirements before any compliance statement is made.
Compare losses, maintenance and lifecycle
Transformer selection should balance purchase price with energy losses, maintenance practice, expected service profile and site access. Ask for model-specific no-load and load losses, temperature-rise basis and the agreed cooling arrangement. The parent category can help buyers identify these questions; guaranteed values belong in the selected model’s technical schedule and test documents.
Define standards, testing and documentation
Include the required standard edition, utility specification, routine tests, type or special tests, witness requirements, drawing approval process and final document list in the enquiry. LONTEN should confirm each requirement against the selected model and available evidence. Management-system certification, product testing and legal market compliance are different items and should be reviewed separately.
Route your enquiry to the right category
Send the application, kVA or MVA, voltage ratio, frequency, installation environment, loss limits, test schedule, quantity and destination. The first response should identify the most relevant transformer family and any missing technical inputs. Continue to the oil-immersed, dry-type or isolation category for detailed configuration and model review.
