Description

Our Three Phase Pad Mounted Transformer (66 kV, 10 MVA) provides a compact, fully integrated solution for reliable, efficient, and safe power distribution. Unlike conventional box-type designs, they combine the high-voltage load break switch and ring main unit switch within the same oil tank, significantly reducing installation space and costs. Fully enclosed and maintenance-free, they deliver long-term stability, strong overload capacity, and superior protection against electrical faults and environmental stress.

Applications

These transformers are widely used in urban and rural distribution networks, residential communities, commercial complexes, industrial plants, substations, and renewable energy projects. They are ideal wherever space is limited, reliable operation is critical, and flexible, cost-effective power distribution is required.

Advantages

• Integrated & Compact Design: Combines transformer, high-voltage load switch, and ring network switch in a single unit.

• Maintenance-Free Operation: Fully sealed structure ensures 20+ years of stable, trouble-free performance.

• Strong Overload Capacity: Handles 2x rated load for 2 hours and 1.6x for 7 hours without reducing lifespan.

• High Reliability & Safety: Sensitive dual fuses and high-quality components improve protection and operational stability.

• Superior Voltage Quality & Lightning Protection: Dyn1 connection, three-phase five-column structure, and insulated lightning arresters.

• Durable & Corrosion: Resistant: Leak-proof, high-pressure-resistant enclosure with special paint for harsh outdoor environments.
