For reliable, efficient power across critical applications, choose Leilang Electric's Oil-Immersed Pad Mounted Transformer (Capacity from 5KVA to 5MVA, voltage up to 35KV available). As a Shanghai-based original transformer factory founded in 2007 with rich R&D and production experience, we offer this fully customizable Single Phase Pad Mount Transformers and Three Phase Pad Mount Transformers designs, provide professional power solutions, and ensure it adheres to IEEE, ANSI standards, UL certification, and ISO quality systems. DOE-compliant and optimized for renewable energy, energy storage, scenic area power distribution, and commercial facilities, it delivers consistent performance with minimal maintenance.
The 50 KVA Single Phase Pad Mounted Transformer is an eco-friendly, high-performance power distribution solution engineered for 13200Y/7620V Grounded Wye Primary and 240/120V Secondary output, featuring biodegradable KNAN fluid and a 304 stainless steel casing—setting it apart from traditional mineral oil and mild steel models. Designed for medium-load single-phase applications, it delivers stable voltage transformation with exceptional durability and environmental compliance, adhering to ANSI, IEEE, NEMA, and DOE 2016 efficiency standards, as well as environmental regulations for biodegradable fluids (GB/T 20197 compliant).
The KNAN (Kinematic Natural Air) cooling system, paired with biodegradable dielectric fluid, ensures efficient heat dissipation (maintaining operating temperature below 85℃ to avoid performance degradation), while the 304 stainless steel casing (18% chromium, 8% nickel composition) offers superior corrosion resistance—ideal for coastal, humid, or harsh outdoor environments. Compact, weatherproof (NEMA 3R rated), and designed for direct concrete pad installation, it supports 24/7 continuous operation with minimal maintenance, boasting a 40+ year design service life.
The 13200Y/7620V Grounded Wye Primary is optimized for North American medium-voltage grids, while the 240/120V split-phase Secondary accommodates mixed residential/commercial loads. This transformer balances performance, sustainability, and compliance, making it a trusted choice for eco-conscious utility, commercial, and residential applications.
- Biodegradable KNAN Cooling & Insulation: Equipped with eco-friendly biodegradable dielectric fluid (compliant with GB/T 20197 and ASTM environmental standards), paired with KNAN natural cooling system—eliminating environmental harm if leaked, while ensuring efficient heat dissipation without external fans/pumps. The fluid also delivers excellent dielectric strength, preventing arcing and extending internal component life.
- 304 Stainless Steel Casing: Heavy-duty 304 stainless steel casing (chromium-nickel alloy) provides superior corrosion, rust, and chemical resistance compared to mild steel cabinets, ideal for coastal, industrial, or humid environments where traditional casings degrade over time. It requires no epoxy coating, supports recycling, and maintains structural integrity for decades.
- 13200Y/7620V Grounded Wye Primary: Standardized 4-wire multi-grounded neutral configuration for North American medium-voltage grids, offering enhanced fault protection, voltage stability, and compatibility with loop/radial feed setups—critical for reliable single-phase power delivery to medium loads.
- High Compliance & Efficiency: Meets ANSI/IEEE C57.12.00, NEMA TP-1, and DOE 2016 efficiency standards (99.1% full-load efficiency), with UL/CSA certification for North American markets. It also complies with GB/T 14285-2006 for protection performance and GB1094.1 for voltage tolerance.
- Versatile & Low-Maintenance: 240/120V split-phase Secondary supports 120V household appliances and 240V heavy-duty equipment; sealed design prevents fluid contamination, requiring only annual fluid sampling and visual inspections. The compact footprint integrates seamlessly with outdoor installations, no protective fencing needed.
