With nearly two decades of experience, DSSD is a professional manufacturer and exporter of complete hydro-generator sets, spare parts, and turnkey EPC (Engineering, Procurement, and Construction) services for hydropower stations worldwide.
The core engineering team originates from Dongfang Electric Group, one of China's largest power equipment manufacturers. Each senior engineer brings over 20 years of hydro-turbine design and manufacturing experience — expertise that directly translates into superior product quality, innovative design, and dependable project execution.
| Model | Technical Specifications | Key Features | Typical Applications |
|---|---|---|---|
| Pelton Turbine (Impulse – High Head) |
• Water Head: 80–1,200 m • Unit Power: 50 kW – 10,000 kW • Runner: Stainless Steel 410 / 13Cr • Speed: 300–1,000 rpm • Frequency: 50 Hz / 60 Hz • Efficiency: 90%–93% • Runner Diameter: 450–2,500 mm |
• Custom stainless steel runners • Extreme high-head capability • Proven in mountainous terrain • Dual frequency compatible |
Mountain-area high-head plants. Widely deployed in Peru, Ecuador, Mexico, and Cameroon. |
| Francis Turbine (Mixed-Flow – Best-Selling) |
• Water Head: 15–300 m • Power Range: 100 kW – 50,000 kW • Installation: Horizontal / Vertical • Runner: 5-Axis CNC Forged Steel • Efficiency: Up to 94.5% |
• Compact structure, stable running • Long service life (50–60 years) • Low maintenance cost • Globally most popular model |
Medium-head hydropower stations. The highest-selling turbine type for global projects. |
| Kaplan Turbine (Axial-Flow – Low Head) |
• Water Head: 3–30 m • Unit Capacity: 100 kW – 20,000 kW • Adjustable-blade design • Adapts to variable flow rates |
• Adjustable runner blades • Handles fluctuating river discharge • High efficiency across variable flow • Optimized for plain-river conditions |
Plain-river, low-head hydropower stations requiring adaptable flow-rate management. |
| Tubular Turbine |
• Water Head: 3–25 m • Power Range: 100 kW – 50,000 kW |
• Compact axial flow design • Horizontal installation • Cost-effective for small hydro |
Low-head small-to-medium hydropower plants and irrigation channels. |
| Turgo Turbine |
• Water Head: 30–300 m • Power Range: 100 kW – 50,000 kW |
• Higher flow capacity than Pelton • Compact runner design • Easy maintenance |
Micro and small hydropower projects where Pelton turbines are less suitable. |
DSSD's manufacturing facility is ISO9001 certified with a state-of-the-art CNC machining workshop and hydraulic simulation laboratory. Every turbine component undergoes rigorous in-house testing before delivery, ensuring optimal efficiency and long-term reliability. Products are CE-approved to meet European safety standards, with stainless-steel runners designed for a 50–60 year operational lifespan.
DSSD has successfully delivered more than 700 hydropower projects across Africa, South America, Central Asia, and Southeast Asia. This extensive track record demonstrates DSSD's ability to adapt solutions to varied geographical and regulatory environments:
Beyond equipment supply, DSSD provides installation guidance, after-sales maintenance, and capacity upgrade services for aging power plants. The technical team works closely with plant operators to extend equipment life, improve efficiency, and increase output — a cost-effective alternative to complete replacement.
For inquiries, partnerships, or technical consultations, DSSD welcomes contact from project developers, EPC contractors, and government energy agencies worldwide.
