Product Description
75kVA 13.2kV to 208Y/120 Three Phase Pad Mounted Transformer | 98.9% Efficient, Fully Sealed
Product Overview
Leilang Electric's 75kVA 13.2kV to 208Y/120 three phase pad mounted transformer is engineered for reliable, cost-effective power distribution in residential neighborhoods, small commercial complexes, schools and light industrial facilities. As a core product in our liquid-filled distribution transformer lineup, it delivers 98.9% industry-leading efficiency that meets and exceeds U.S. DOE 2016 energy efficiency standards, cutting long-term operational costs by reducing energy waste.
Its fully sealed oil-immersed design eliminates oil oxidation and moisture ingress, extending service life to 30+ years and minimizing maintenance requirements. All live components are completely enclosed within a grounded steel tank, providing inherent safety for public areas without the need for additional fencing. Manufactured in strict accordance with the latest ANSI C57 and IEEE standards, this transformer supports both radial and loop feed configurations, offering flexible installation options for diverse grid architectures.

Frequently Asked Questions (FAQ)
Q: What efficiency standard does Leilang's 75kVA pad mounted transformer meet?
A: Our 75kVA transformer achieves 98.9% full-load efficiency, which meets and exceeds the U.S. Department of Energy (DOE) 2016 energy efficiency requirements for distribution transformers.
Q: What are the benefits of the fully sealed design?
A: The hermetically sealed welded tank prevents air and moisture from entering, eliminating oil oxidation and degradation. This means no routine oil changes are needed, extends the transformer's service life to 30+ years, and provides superior safety by fully enclosing all live components.
Q: Can this transformer be used in both radial and loop feed systems?
A: Yes, it is designed to support both radial and loop feed configurations, making it compatible with most North American distribution grid architectures.
Q: What warranty does Leilang Electric provide for this transformer?
A: We offer a 24-month warranty from the date of shipment. During the warranty period, we provide free replacement of defective parts and technical support. We also include free spare parts for common wear items with bulk orders.
Q: Can you customize the voltage ratings or other features?
A: Yes, as a manufacturer with an in-house R&D team, we offer full OEM/ODM customization. We can adjust voltage ratios, add smart monitoring features, change tank color, or modify other specifications to meet your project requirements.
Q: How long does installation take?
A: Our transformers are fully pre-assembled and tested at the factory. Installation typically takes 1-2 days, requiring only placement on a concrete pad and connection to the incoming and outgoing power lines.
Q: What is the minimum order quantity?
A: We accept orders as low as 1 unit for standard models, making it easy to test our product quality or fulfill small project needs.
