Product Overview

The 500kVA Three-Phase Pad-Mounted Transformer offers a robust, energy-efficient solution for medium to large commercial, industrial, and utility applications. Designed for outdoor installations, this transformer provides stable and reliable power distribution with minimal maintenance. Its oil-immersed cooling system ensures optimal performance, even in demanding environments, while the tamper-proof design provides security and longevity. Ideal for applications requiring a constant, balanced power supply, the 500kVA transformer is engineered to meet high-performance standards and to withstand the rigors of continuous operation.

Features
  • Rated Capacity: 500 kVA
  • Type: Three-Phase, Pad-Mounted, Oil-Immersed
  • Primary Voltage: Customizable (e.g., 11kV, 13.8kV, 12.47kV)
  • Secondary Voltage: Customizable (e.g., 480Y/277V, 208Y/120V)
  • Frequency: 50Hz / 60Hz
  • Cooling Method: Oil Natural Air Natural (ONAN)
  • Temperature Rise: 65°C (standard)
  • Tap Changer: Off-circuit tap changer ±2×2.5% (customizable)
  • Protection Rating: IP23 (Optional: IP44, IP54 for more severe environments)
  • Insulation Level: BIL 95kV or according to customer specifications
  • Enclosure: Weatherproof, tamper-resistant design (ANSI/IEEE standards compliant)
  • Noise Level: ≤ 55 dB (low noise for residential and urban applications)
  • Weight: Approx. 2500-3000 kg (depending on configuration)
Benefits
  • Energy-Efficient Operation: High-performance core and winding design minimize energy losses, reducing operational costs.
