Frequently Asked Questions
What size concrete pad do I need for a 2000.0 kVA padmount transformer?
A 2000.0 kVA padmount transformer requires a minimum pad size of 144″ × 144″ with 4-6 inches thickness of reinforced concrete.
How much does a 2000.0 kVA padmount transformer weigh?
A 2000.0 kVA padmount transformer weighs approximately 12400 lbs (5625 kg) including oil.
What is the difference between dead-front and live-front padmount transformers?
Dead-front designs (like this 2000.0 kVA unit) have all connections inside the locked cabinet with no exposed live parts. Live-front designs have bushings exposed on top, requiring additional safety barriers in public areas.
