Description
Three Phase Dry Type MV & HV Electrical Distribution Transformers 300kVA
Our three-phase dry type distribution transformers are engineered for medium voltage (MV) and high voltage (HV) power networks, delivering reliable and safe electricity distribution for industrial plants, commercial centers, residential complexes, and public facilities.
With available ratings of 300kVA, these transformers are optimized for small to medium-scale loads, ensuring stable operation of equipment including HVAC systems, lighting, pumps, elevators, and production machinery.
The dry type insulation design eliminates the need for oil, providing fire resistance, moisture resistance, and eco-friendly operation. They feature low losses, low noise, and high efficiency, making them suitable for indoor installations in urban or environmentally sensitive areas.
Key Advantages
  • Safe & Fire-resistant - Resin-cast insulation, no oil leakage or explosion risk
  • Energy Efficient - Low no-load and load losses, reduced operational costs
  • Reliable Cooling - Air natural (AN) / Air forced (AF) cooling options
  • Low Noise - Quiet operation suitable for residential and commercial buildings
  • Easy Installation & Maintenance - Compact design, minimal servicing required
Application Areas
  • Commercial buildings & shopping centers
  • Industrial facilities & manufacturing plants
  • Hospitals, schools & public infrastructure
  • Residential communities & mixed-use developments
  • Renewable energy projects (solar & wind power integration)
