Encapsulated Dry Type Transformer
Construction
When you look at an encapsulated dry type transformer, you see a design built for tough environments. Manufacturers use several construction methods to make sure these transformers last and perform well. Here’s a quick table to help you understand the main methods:
| Construction Method | Description | Applications |
|---|---|---|
| VPI (Vacuum Pressure Impregnation) | Uses high-temperature insulation and a polyester sealant applied under vacuum pressure. | Great for commercial and industrial spaces, up to 30 MVA. |
| VPE (Vacuum Pressure Encapsulated) | Similar to VPI but uses silicone resin and a thicker coating. | Works well in places with acids, alkalis, or high humidity. |
| Cast Coil | Coils are solidly cast in resin under vacuum for precision. | Perfect for buildings, tunnels, and offshore platforms. |
You’ll also find open wound and sealed designs. In these, the windings get dipped and baked, then sealed in silica and epoxy. This process keeps out dust and moisture, making the transformer reliable even in harsh settings.
Materials and Epoxy Resin
The heart of an encapsulated dry type transformer lies in its materials. You often see epoxy resin used for encapsulation. Why epoxy? It brings excellent electrical insulation, strong moisture resistance, and solid mechanical strength. Other materials like polyester, polyurethane, varnish, and silicone also play a role, but epoxy stands out for its all-around performance.
Here’s a table showing why epoxy resin is so popular:
| Benefit Description | Details |
|---|---|
| Environmental Protection | Withstands harsh conditions and keeps water out |
| Thermal Performance | Moves heat away from the core and windings |
| Reliability | Offers strong insulation and reduces electrical faults |
| Noise Reduction | Makes the transformer run more quietly |
Note: Epoxy resin not only protects the transformer but also helps it last longer and work more quietly.

How Encapsulated Transformers Work
Basic Principle
When you use encapsulated transformers, you rely on a simple but powerful principle. These transformers transfer electrical energy between circuits using electromagnetic induction. The core and windings sit inside a sealed enclosure. This design keeps out dust, moisture, and other harmful elements. You get a device that works quietly and safely, even in tough environments. Encapsulated transformers help you step voltage up or down, making sure your equipment gets the right power every time.
Step-by-Step Operation
You might wonder how to set up and operate encapsulated transformers. Here’s a step-by-step guide to help you:
- Measure the output voltage before you energize the transformer. Make sure it matches the nameplate voltages.
- Connect all primary taps for each coil to the same percentage tap positions, especially when windings run in parallel.
- Ground the enclosure with a conductor that fits the size requirements.
- For three-phase encapsulated transformers, check that the load is balanced across all phases.
- Inspect the clearance and tightness of every electrical connection.
- If you use a single-phase 3-wire 240/120 volt load, keep the neutral current below half the transformer’s kVA rating.
Tip: Following these steps helps you get the best performance and safety from your encapsulated transformers.
Impact of Encapsulation
Encapsulation changes the game for transformer performance and lifespan. Take a look at how it helps:
| Advantage | Explanation |
|---|---|
| Improved Durability | Encapsulated transformers have a metal casing that shields them from damage and extends their life. |
| Enhanced Safety | The enclosure blocks out harsh environmental factors, making these transformers ideal for demanding locations. |
| Better Thermal Management | The casing moves heat away from the core, cutting down on overheating and keeping things running smoothly. |

Epoxy Encapsulated Transformers Advantages
Environmental Protection
When you choose epoxy encapsulated transformers, you get a big boost in environmental protection. These transformers use a solid epoxy resin that seals every part inside. You don’t have to worry about oil leaks or messy spills. The resin keeps moisture, dust, and dirt out. You also cut down on fire hazards because there’s no flammable oil inside. Maintenance becomes easier, so you spend less time and money keeping things running.
Here’s a quick look at how epoxy encapsulated transformers compare to non-encapsulated types:
| Benefit | Epoxy Encapsulated Transformers | Non-Encapsulated Types |
|---|---|---|
| Oil Leakage Risk | No risk | High risk |
| Fire Hazard | Reduced | Increased |
| Maintenance | Lower | Higher |
Tip: If you work in places with lots of dust or moisture, epoxy encapsulated transformers help keep your equipment safe and clean.
Safety and Reliability
Epoxy encapsulated transformers give you peace of mind. You get strong protection from moisture, dust, and dirt. The resin makes the transformer tough against vibrations and shocks. You also avoid corrosion, which means a longer lifespan. The non-flammable material helps prevent fires. You stay safe because the insulation keeps you away from live electrical parts.
- Protection from environmental factors
- Vibration and shock resistance
- Protection against moisture and corrosion
