75kVA 13.2kV Three Phase Pad Mount Transformer Electrical Fully Sealed
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.
-
98.9% DOE 2016 Certified Efficiency
- Uses high-grade grain-oriented silicon steel core and 100% copper windings
- Ultra-low no-load loss (180W) and load loss (1250W)
- Saves over 1,500 kWh of electricity annually compared to standard transformers
- Reduces carbon footprint and lowers total cost of ownership
-
Fully Sealed Welded Tank Construction
- One-piece welded tank from cover to base, no gaskets to leak
- Hermetically sealed system prevents oil degradation and contamination
- No routine oil changes required, cutting maintenance costs by 70%
- All live parts fully insulated and enclosed, eliminating accidental contact hazards
-
Comprehensive Safety Protection
- Automatic pressure relief valve (35 SCFM) for overpressure protection
- Three-point latching system with interlocked doors (HV door only opens after LV door)
- Rigid steel partitions between high and low voltage compartments
- ANSI standard ground pads for secure electrical grounding
-
Flexible & Reliable Operation
- Supports both radial and loop feed arrangements
- 5-position tap changer (±2*2.5%) for voltage regulation
- 65°C average winding rise, Class E insulation (120°C)
- Operates reliably in temperatures from -40°C to +40°C (-40°F to 104°F)
- Low noise level (51 dBA) for quiet operation in residential areas
-
Factory Pre-Assembled for Fast Installation
- Fully tested and pre-wired at our manufacturing facility
- Ready for immediate installation on a concrete pad
- Ground-level access for all maintenance tasks, no climbing required
- Standard 1-inch drain valve and oil sampler for easy inspection
