With the development of society and the continuous improvement of people's material living standard, there are more and more power demands in different situations, such as data centers, modern office buildings, poly-silicon production plants, mining sites etc.. Commonly used low-voltage 400V AC diesel generator sets have large transmission lines, large line losses, which are difficult to lay out with high cost. In many cases, it is difficult to meet real demand. At this situation, high-voltage generator sets can fully reflect its value.

As prime or standby power supply for diesel generator sets, the capacity requirements are getting larger and larger.A few big power diesel generator sets need to be connected to the single unit or connected to the grid to meet the power requirements of the load. As Gensets quantity increases, it is necessary to build a separate machine room, and the distance from the actual use load is getting farther and farther. There are transmission defects in the parallel operation of multiple low-voltage diesel generator sets. In order to be safer and more reliable, the use of high-voltage Genset is undoubtedly the best choice.

The development and improvement of big power diesel engines, large-capacity high-voltage alternators and control system technology have made the advantages of high-voltage diesel generator sets gradually appear, and the market demand is strong, which has become a main solutions of emergency power supply for large-capacity, long-distance transmission, high intelligence and high reliability. 

High-voltage Gensets are widely used in high-end service industries such as telecommunications, metallurgy, airports, mining sites, ocean islands, large data centers, large-scale urban complexes, black start for medium and large-scale power plants, and prime or backup power systems for high-end manufacturing.

1. Voltage is high. Domestic markets need 6.6KV, 10.5KV; Markets for 60HZ frequency need 6.6KV, 13.8KV.
2. The capacity of the single Gen-set is large. Generally, it is above 1000KW, which can realize parallel operation of many units. The maximum quantity are 256 units.
3. Output current is small, which can transmit power over long distances and has less line loss in transmission and distribution.
4. The load distribution mode is flexible. The Gen-set can directly power high voltage load or power the low voltage load through transformer.
5. High automation. It integrates the protection, measurement, remote control, remote signaling, telemetry and signal of the electrical system to realizes the comprehensive automation of the electrical system with the function of protection and alarm signal and transmitted to the control center.
1. Equipped with large-capacity buried oil tanks to meet the requirements of long-term operation of each unit.
2. Configured with various power distribution cabinets, such as inlet and outlet cabinets, PT cabinets, grounding resistor cabinets, etc.
3. Remote monitoring and operating system.
4. The structure of the machine room can be designed according to actual needs.
5. Customize the container canopy according to the actual application environment.
6. Comply with the requirements of BS EN 60034 and other international standards (e.g. BS5000, VDE 0530, Nema MG1-32, IECEN60034, CSA C22.2-100 and AS1359).
7. High-voltage transmission makes small voltage drop and low comprehensive costs.
8. The products can supply for high-voltage load directly. Few high-voltage parallel devices make a simple system, few fall point and easy use.
9. Large capacity, ability of distant supply, centralized construction of generating set rooms, high reliability and safety, etc.
10. Voltagegrade: 6 kV、6.3 kV、6.6 kV、10 kV、10.5 kV、11 kV.
1. All Gensets' design are based on professional fluid software for simulation and analysis.
2. All Gensets' cooling systems use 50 ℃ as a reference.
3. Engines and alternators are selected from international famous brands
4. High degree of customization can be fully customized according to users' requirements.
