Product Overview

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.

Key Features
  • 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.

Frequently Asked Questions
How does three-phase design benefit this 50KVA transformer compared to single-phase models?
Three-phase design delivers balanced power distribution, reducing voltage drop and energy loss—critical for 50KVA loads. It handles higher power demands more efficiently than single-phase units, supports industrial/commercial equipment that requires three-phase power (e.g., motors, compressors), and minimizes wear on internal components by distributing load evenly across three windings, extending service life.
What makes the biodegradable KNAN fluid different from traditional mineral oil, and what environmental benefits does it offer?
Unlike non-biodegradable mineral oil, the biodegradable KNAN fluid complies with GB/T 20197 standards, breaking down naturally in soil/water within 90 days if leaked, eliminating environmental contamination risk. It also has similar dielectric strength to mineral oil, while the KNAN cooling system (paired with the fluid) maintains lower operating temperatures (below 85℃) than ONAN systems, reducing energy loss and extending component life.
Why is 304 stainless steel casing a better choice than mild steel for this transformer?
304 stainless steel (18% chromium, 8% nickel) forms a protective oxide layer that resists corrosion, rust, and chemical damage—critical for outdoor, coastal, or humid environments where mild steel (even with epoxy coating) degrades over 5-10 years. It requires no repainting, supports recycling, and maintains structural integrity for 40+ years, reducing long-term replacement costs.
Is the 13200Y/7620V Grounded Wye Primary compatible with single-phase utility grids, and can it replace lower-voltage single-phase transformers?
Yes. The 13200Y/7620V Grounded Wye Primary is a standard single-phase configuration for North American medium-voltage grids, compatible with both loop and radial feed setups. It can replace lower-voltage (e.g., 7200V) single-phase transformers, supporting higher medium-voltage input while delivering stable 240/120V output for 50KVA medium loads.
What maintenance is required for the biodegradable KNAN fluid, and how often does it need to be replaced?
The biodegradable fluid requires minimal maintenance—annual fluid sampling to check dielectric strength and moisture content, per IEEE standards. Unlike mineral oil (which needs replacement every 15-20 years), the KNAN fluid has a 25+ year service life under normal operating conditions, reducing maintenance costs and environmental impact.
Can this 50KVA single-phase transformer handle peak loads, and what is its overload capacity?
Yes. It is engineered to handle 110% peak load for 8 hours continuously and 125% overload for 1 hour. The KNAN cooling system and 304 stainless steel casing efficiently dissipate heat during peak loads, preventing overheating and ensuring stable performance even in high-temperature environments.
