Key Takeaways
- 160 kVA oil‑immersed transformer is optimized for commercial building scenarios, focusing on compact footprint, low noise, overload tolerance and fire‑safety performance.
- Compact dimension fits basement and outdoor utility zones; optimized structure keeps noise ≤56 dB@1m, meeting commercial‑area noise requirements under IEC 60076‑10.
- High‑purity copper winding and silicon‑steel core support 120 % rated overload for 2 hours to cope with weekend and peak commercial power consumption.
- High flash‑point insulating oil plus anti‑corrosion galvanized tank enable both indoor basement and outdoor installation, expected service life over 25 years under sealed condition.
- When ordering, clarify voltage ratio, altitude, ambient condition, IP protection grade, local efficiency standard and required test reports.

Design Features of 160 kVA Oil Filled Transformer for Commercial Use
- Compact tank: 1700 × 1150 × 1550 mm - easy to install in commercial-building basements or outdoor utility areas with limited space.
- Low noise: noise-damping structure (optimized core clamping + oil buffer layer) keeps operating noise at ≤ 56 dB at 1 m, complying with commercial-area noise limits; verify by test per IEC 60076-10.
- High-load adaptability: high-purity copper windings and a cold-rolled silicon-steel core handle 120% of rated load for 2 hours - critical for commercial peaks such as mall weekends (overload capability per IEC 60076-7 guidance).
- Fire-safe insulation: high-flash-point insulating oil (flash point ≥ 140 °C per the oil specification) with a fire-retardant tank coating reduces fire risk in high-foot-traffic areas.
Performance Advantages of 160 kVA Oil Filled Transformer
- High energy efficiency: no-load loss as low as 320 W with load loss of 1850 W (160 kVA) - corresponding to a high efficiency class per GB 20052; for a commercial building operating 8760 hours/year, the loss saving versus a standard unit can be quantified as Δloss × operating hours (e.g., roughly 1200 kWh/year at typical loading).
- Stable voltage output: off-circuit tap changer (±2 × 2.5%) adjusts output within ±5%, protecting sensitive equipment (POS systems, HVAC controls, elevator motors).
- Weather resistance: 3 mm galvanized-steel tank with anti-corrosion powder coating resists rain, humidity and UV for outdoor installation.
- Long service life: the sealed tank minimizes oil contamination, supporting a 25+ year service life.
