Product advantages
1.Full rated output at high altitude – no de‑rating.
--Specifically designed for 3600m with reinforced insulation (95kV withstand). Delivers full 3600kVA without capacity reduction.
2.High losses lead to rising electricity bills year after year.
--Advantage: Low-loss design – saves significant energy costs every year
Load loss 33,065W, no-load loss 8,100W – both better than GB limits. Significantly reduces total cost of ownership over time.
3.Low withstand voltage may cause failure during on-site acceptance tests.
--95kV high withstand – passes site acceptance with no surprises
HV power frequency withstand 95kV, LV 28kV; induced overvoltage 200% at 150Hz for 40s. Full test reports provided – smooth acceptance guaranteed.

Why SC-3600/34.5 is the solution to your toughest requirements
Pain Points & Solutions:
1. High-altitude operation risk – Standard transformers require de-rating above 3000m, and insulation breakdown is more likely.
✅ High-altitude reinforced insulation – Withstand voltage 95kV (vs. standard 70kV), no de-rating at 3600m, full load stable output.
2. Overheating shutdown due to insufficient cooling – No forced air cooling on site, concern about winding burnout under full load in summer.
✅ AN natural cooling + large temperature rise margin – No fans required; winding temperature rise ≤91K, well below the GB limit of 100K, safe for long-term full-load operation.
3. High electricity cost pressure – Transformer losses accumulate year after year, making energy cost a major expense.
✅ Low-loss design – Load loss 33,065W / No-load loss 8,100W, better than GB standards, significantly reduces total cost of ownership (TCO).
4. Project delay due to long lead time – Suppliers deliver slowly, and no one responds to urgent orders.
✅ Flexible delivery – Standard lead time 30–45 days, expeditable to 25 days for urgent projects; 2-year warranty + long-term technical support.
Customer reviews
1.At 3,400m altitude, the SC-3600/34.5 delivers full 3600kVA with no derating. The 95kV withstand voltage passed site acceptance easily.
– Javier Rodríguez
2.AN cooling kept the transformer safe under full load even in high ambient temperatures. We also saw monthly electricity bills drop.
– Maria Santos
3. Expedited delivery in 28 days saved our project timeline. Dyn11 handles fluctuating solar inverter loads without any issues.
– Samuel Omondi, Green Energy East Africa, Kenya
4.IP23 enclosure keeps out snow and ice at 3,500m. The low no-load loss saves us energy during off-peak hours.

Application scenarios
Reliable Power Supply for High-Altitude Mines (Up to 3,600m)
---High reliability power supply suitable for high-altitude mines at an altitude of 3600 meters
This 3600kVA dry-type transformer is specifically designed for mining operations at altitudes up to 3,600 meters. The AN (self-cooling) design eliminates fans that easily clog with dust and debris in plateau environments. With 34.5kV input and 4.16kV output, it directly powers large crushers, ball mills, and conveyor systems without intermediate transformers. Even in thin air with reduced cooling capacity, it delivers full rated output without derating, reducing maintenance costs and unplanned downtime.
Fan-Free Operation for Plateau Tunnels and Underground Projects
---Windless operation scheme suitable for high-altitude tunnels and underground engineering
Engineered for tunnels and underground worksites where ventilation is poor and maintenance access is limited. This transformer uses AN self-cooling — no moving parts, no fan failures, no filter changes. Its oil-free design meets strict fire safety codes for underground spaces. The 3600kVA capacity supports tunnel boring machines (TBMs), ventilation fans, lighting, and signaling systems throughout construction and ongoing operations. Robust insulation withstands the humidity and temperature swings common in deep excavations.
