1000kva 500kva 3-phase Pad Mounted Transformer
These transformers are installed at ground level on concrete pads, hence their name. They are strategically placed close to buildings or along streets to minimize power loss over long distribution lines. Their location ensures efficient power distribution and ease of maintenance.

Q: What Is The Difference Between Loop Feed And Radial Feed?
Q: What is the difference between a delta and wye connection in transformers?
Wye Connection: The windings connect to a common point (neutral), providing a stable voltage supply. It's often used for lighting and small equipment.
