Lightning Transformers (VPI Dry Type)

Lightning Transformers

Product RangeUpto 5 MVA
VoltageUpto 33KV

VPI Dry Type Lightning Transformers protect electrical systems from high-voltage surges caused by lightning strikes and switching transients. They act as surge buffers, ensuring critical equipment and circuits remain unaffected by sudden overvoltage conditions.

With advanced resin insulation and fast response characteristics, these transformers ensure reliable protection and voltage regulation. Their oil-free construction and robust design make them ideal for both indoor and outdoor surge-protection applications.
