- For one-stop purchasing, it’s best to first organize the product categories, models, quantities, and intended uses on-site.

- For items on the list that do not have a specific model number, please attach a photo or drawing; do not substitute a vague description.
Many purchase inquiries are not for a single instrument, but rather for a batch of transformer components purchased together. For example, a dry-type transformer project may involve temperature controllers and cooling fans; an oil-immersed transformer project may involve oil-surface temperature controllers, winding temperature controllers, oil level gauges, gas relays, and pressure relief valves; and retrofit projects may also include the addition of online monitoring devices.
The product categories available from Innotongda include transformer temperature controllers, dry-type transformer temperature controllers, oil-filled transformer temperature controllers, temperature and humidity controllers, dry-type transformer cooling fans, online monitoring systems, transformer oil level gauges, gas relays, and pressure relief valves. Among the available products, dry-type transformer temperature controllers include BWDK-326, IB-S201, etc.; cooling fans include GFDD470-110, GFDD590-150, GFD500-175, etc.; Oil level gauges include the YZF3-200 and YZF2-200; pressure relief valves include the YSF9-70K/80K, YSF9-80K/130K, and YSF series with Φ25mm and Φ50mm orifices, among others.
| Component Category | View Product Examples | Suggestions for Filling Out the Checklist |
|---|---|---|
| Dry-type transformer thermostat | BWDK-326, IB-S201 | Model, Features, Cutout Dimensions, Communication/Output Requirements |
| Cooling Fans | GFDD470-110, GFDD590-150, GFD Series | Model, Length, Impeller Diameter, Voltage, Quantity |
| oil level meter | YZF3-200, YZF2-200 | Flange dimensions, rocker arm length, and whether remote transmission is required |
| pressure relief valve | YSF9-80K/130K, YSF Φ25/Φ50 | Nominal Diameter, Opening Pressure, Signal, Mounting Type |
| Online monitoring | Combined Online Monitoring, 3-in-1 Oil Temperature, Level, and Pressure Sensor | Monitoring Items, Connection Methods, Number of On-Site Units |
When compiling a list, we recommend that customers avoid simply writing “10 thermostats, 20 fans.” The purchase list should clearly specify the purpose, original model number, quantity, whether the item is a replacement for an old part, and any special functional requirements for each item. For example, for thermostats, specify whether RS485/232 or 4–20 mA is required; for fans, specify whether they are GFDD top-blow or GFD side-blow types; for oil level gauges, indicate whether they are remote-transmitting; and for pressure relief valves, provide details such as the nominal diameter and opening pressure. If you are unsure, attach on-site photos or the original nameplate.
For the sales team, a complete list makes it easier to determine whether all items can be supplied together; for customers, it also reduces the need for repeated communication.
Related FAQs
1. Should brands be listed on the one-stop shopping list?
If the original equipment has a brand name and model number, please specify them; if not, please provide photos, dimensions, or drawings.
2. Can I request a quote for both the thermostat and the fan?
Yes. In dry-type transformer projects, the temperature controller and cooling fan often need to be verified together.
3. What components of an oil-immersed transformer need to be organized?
Common examples include oil-surface temperature sensors, winding temperature sensors, oil level gauges, gas relays, and pressure relief valves.
4. What should I do if I'm not sure of the model number?
Send the nameplate, installation location, and photos of the old parts to the supplier for an initial assessment.
5. Can you confirm the inventory and delivery time directly?
Not recommended. Inventory and lead times are subject to change; please refer to actual communications.
