Product-family description · impregnated dry-type transformer
Fulin’s impregnated dry-type page gives operating-environment limits and a temperature-protection description, but no capacity-by-model electrical table. The strongest use of this record is to prepare a site and duty brief, then request the exact offered model. It does not support a guessed kVA range, loss schedule or fire-performance certification.

Shenyang Fulin Special Transformer →CATALOGUE IDENTITY
Impregnated dry-type family (model code not stated)- Construction family
- Impregnated dry-type
- Published altitude limit
- ≤1,000 m
- Ambient maximum
- +40 °C; daily average +30 °C
- Model / capacity schedule
- Not published in reviewed page
Check maximum, average and minimum temperatures separately
The manufacturer gives a maximum ambient of +40 °C, highest daily average +30 °C and highest annual average +20 °C. Those are separate conditions, not three alternative ambient ratings. Provide both site extremes and the relevant average conditions so the supplier can review the actual installation.
The stated minimum is −30 °C for outdoor-type transformers and −5 °C for indoor-type transformers. The product-family title does not establish which outdoor or indoor configuration is supplied. An outdoor temperature statement also does not identify an enclosure protection rating, rain protection or terminal weatherproofing. Confirm the offered installation type and package explicitly.

| Item | Published reference | Buyer action |
|---|---|---|
| Altitude | No higher than 1,000 m | Provide actual altitude and ask for any design variation. |
| Maximum ambient | +40 °C | State the highest expected room/site temperature. |
| Daily / annual averages | +30 / +20 °C maxima | Return average-condition information separately. |
| Minimum ambient | −30 °C outdoor; −5 °C indoor | Confirm the selected installation type and enclosure. |

Keep the construction identity and electrical gaps visible
This reference is titled impregnated dry-type transformer. A separate neighbouring product link identifies a cast dry-type product; it is not a technical appendix for this family. Do not transfer cast-resin catalogue capacities, winding materials or losses into this record.
The reviewed page does not identify an exact model, rated capacity, voltage ratio, frequency, tap range, connection, impedance, numerical losses, dimensions or mass. These are open configuration fields. Ask the maker to return one current rating sheet and layout, with the insulation treatment and winding materials specified for that design.
The source states that the supply voltage waveform should approximate a sine wave and gives a qualitative symmetry condition for multiphase supply. It does not specify harmonic limits, unbalance tolerance or a converter-duty rating. Describe the actual loads and supply characteristics when requesting suitability.
Source notes: [P1]
Convert protection claims into an acceptance scope
The page describes a temperature-protection control system and makes qualitative claims about low loss, partial discharge, noise, mechanical strength and short-circuit resistance. It provides no numerical test schedule in the reviewed material. Ask for sensor locations, alarm and trip functions, controller scope and their verification procedure instead of assuming a particular supplied device.
Its broad application list includes load centres and locations with special fire requirements. The “100% humidity” and fire-related statements are manufacturer descriptions without a matched classification or report here. State condensation, contaminants, ventilation and fire requirements; request applicable evidence for the exact proposed unit. Do not treat the application list as approval for every listed environment.
Identify the supplied design
Receive the model, rating sheet, installation type and construction specification.
Review site compatibility
Have the maker address ambient averages/extremes, altitude, supply waveform and exposure against that design.
Agree functional acceptance
Specify temperature alarms/trips, electrical tests, numerical guarantees and report identities before release.

Ask for a complete configured offer
An inquiry should describe the load requirement before asking for a price. Include capacity, voltage ratio, duty, room or outdoor conditions, enclosure, terminal interfaces and protection contacts. Ask the supplier to identify what is included and what requires a separate selection or engineering review.
No verified price or lead time is available. Require a dated quotation for the returned design with currency, trade term, enclosure/controller/test/packing scope and exclusions. Request a schedule beginning at an explicit approval or order event and showing manufacture, tests, dispatch and destination arrival separately. The manufacturer’s qualitative maintenance claim is not a priced service agreement; obtain installation and maintenance instructions as part of handover.

Buyer questions
What kVA range can I select from this page?
The reviewed page supplies no capacity schedule. Provide the requirement and request the maker’s current model-specific proposal.
Does −30 °C apply to an indoor unit?
The source assigns −30 °C to outdoor type and −5 °C to indoor type. Confirm the offered installation configuration.
Does “100% humidity” prove condensation suitability?
The statement lacks a configuration-specific test basis here. Describe actual condensation and exposure and obtain an explicit assessment.
Can I use the cast dry-type data for this family?
No. The neighbouring cast product is a separate reference. Request data for the impregnated design itself.
