37.5 KVA Vacuum Pressure Impregnated (VPI) Transformer 2.4KV To 240V DOE 2016 IEEE ANSI  Three Phase  Dry Type Ventilated

 

 

Overview

 

The Winley 37.5 kVA Vacuum Pressure Impregnated (VPI) dry-type transformer is engineered for reliable, high-efficiency power distribution in commercial and industrial environments. Designed and built to exceed industry standards, this unit offers robust insulation, low noise, and a compact footprint for pad- or floor-mounted installations indoors or outdoors (NEMA 3R).

 

    

 

Key Features

 

  • Transformer Type: Vacuum Pressure Impregnated (VPI) dry-type, ventilated construction for long-term insulation reliability and moisture resistance.
  • Capacity: 37.5 kVA (up to 6000kva)
  • Voltage: Primary 240 V , Secondary 2400 V .
  • Primary class 1.2 kV; secondary class 2.5 kV.
  • Vector Group: II6.
  • Insulation & Thermal: Class H insulation; 80°C temperature rise; temperature sensors and gauge included.
  • Cooling & Fans: ANN (natural air cooling). No forced-air fans — lower maintenance and quieter operation.
  • Winding Material: Copper for superior conductivity and reliability.
  • Acoustic Performance: Approximately 55 dBA sound level for quiet operation in sensitive environments.
  • Efficiency: Meets or exceeds DOE 2016 efficiency standards; typical operating efficiency up to 99.00% (measured at 50% of nameplate kVA).
  • Losses: No-load losses approx. ±840 W; full-load losses approx. ±4,500 W; total load losses approx. ±5,340 W 
  • Mechanical: NEMA 3R coated steel enclosure with ANSI ; Pad mount or floor mount options. 
  • Altitude & Ambient Rating: Rated for operation up to 3,300 ft (1,000 m) elevation and ambient up to 40°C.
  • Safety & Compliance: NRTL listed for the U.S. and Canada; complies with ANSI/IEEE C57.12.00, C57.12.01, C57.12.35, C57.12.59, C57.12.70; meets/exceeds CSA and NEMA ST-20 standards; RoHS and CE certified. Seismic bracing included for earthquake-specific installations.

Benefits

 

  1. High reliability and long service life: VPI process and Class H insulation protect windings from moisture and contaminants and reduce partial discharges.
  2. Low maintenance: Natural air cooling (ANN) and no fans mean fewer moving parts to service.
  3. Energy efficiency: Designed to meet DOE 2016 efficiency levels, reducing operating costs and losses over the transformer lifecycle.
  4. Quiet operation: 55 dBA sound rating suits commercial or noise-sensitive installations.
  5. Safety and compliance: Constructed to meet major North American and international standards, simplifying approvals and permitting.
  6. Flexible installation: NEMA 3R weatherproof enclosure and seismic bracing enable indoor or outdoor pad- or floor-mounted installation.
