Grid-Tied Three-Phase Pad Mounted Transformer 2500kVA for Utility Grid & Solar

The Three-Phase Pad Mounted Transformer (Box-Type Transformer) is a fully enclosed, ground-mounted power distribution solution designed for safe, reliable, and high-efficiency energy transformation in modern power networks. It is widely used in grid-tied solar plants, utility substations, industrial parks, residential communities, and commercial power distribution systems.

Engineered with a compact, tamper-proof, and weather-resistant enclosure, this transformer ensures stable operation under harsh outdoor conditions, including high temperature, humidity, dust, and coastal corrosion environments.

With power ratings up to 2500kVA, it provides efficient voltage conversion for medium-voltage distribution networks and is fully compliant with international standards such as IEC 60076, ANSI/IEEE C57.

• High Capacity Up to 2500kVA
  Designed for large-scale grid and industrial power distribution applications with stable high-load performance.
• Fully Enclosed & Tamper-Proof Design
  Ensures maximum safety for public areas such as residential zones, solar farms, and urban distribution networks.
• High Temperature & Harsh Environment Adaptability
  Special insulation and cooling design for tropical, desert, and coastal regions with extreme climate conditions.
• Low Loss & High Efficiency Core Design
  Uses high-grade silicon steel core to reduce no-load losses and improve energy efficiency.
• Flexible Configuration for Grid Integration
  Compatible with renewable energy systems such as solar PV and wind power grid connection.
• Maintenance-Free Outdoor Operation
  Sealed tank design reduces maintenance cost and ensures long operational life.

In regions such as Southeast Asia, the Middle East, Africa, and tropical coastal countries, power distribution systems face critical challenges:

• Extreme ambient temperatures leading to transformer overheating
• High humidity causing insulation degradation
• Coastal corrosion affecting metal enclosures
• Risk of thermal runaway and abnormal oil expansion
• Dust and sand infiltration in outdoor installations
• High load fluctuation in growing urban grids

To address these challenges, our pad-mounted transformer is engineered with advanced thermal and safety designs:

• Enhanced Cooling System (ONAN Optimization)
  Improved oil circulation and heat dissipation structure to prevent overheating in +50°C environments.
• High-Temperature Resistant Insulation System
  Uses Class F or Class H insulation materials to ensure stable dielectric strength under extreme heat.
• Anti-Explosion Pressure Relief Device
  Built-in pressure relief valve to prevent internal pressure buildup and reduce explosion risk.
• Anti-Corrosion Enclosure Treatment
  Hot-dip galvanized steel + epoxy powder coating for coastal and humid environments.
• Hermetically Sealed Tank Design
  Prevents moisture ingress and minimizes oil oxidation and self-degradation.
• Dust & Sand Protection Design
  IP-rated enclosure ensures stable operation in desert and dusty environments.
