Prefabricated Substation (European Style)
Safe and Reliable: The packaged substations are equipped with comprehensive electrical protection features, including overloading, short-circuit, and grounding protections. The transformers themselves are fitted with non-electrical protections such as temperature, oil level, pressure, and gas monitoring. Moreover, the system can be monitored in real time from the background control center, and remote operations can be performed from there, ensuring the continuous safe operation of the equipment at all times. High Integration: The entire system is pre-manufactured in the factory, fully integrated and thoroughly tested before being delivered to the site as a complete unit. On-site installation involves simply connecting high- and low-voltage cables as well as control and communication cables, significantly reducing on-site workload and boosting construction efficiency. Energy-Efficient and Environmentally Friendly: The transformers are made from energy-saving and environmentally friendly materials, and their design has been optimized to minimize no-load losses and enhance operational efficiency, meeting national energy-saving standards. An advanced cooling system is employed to lower operating temperatures, improve heat dissipation efficiency, and reduce energy losses. Flexible Configuration: Whether it’s a photovoltaic power generation or wind power generation project, we can provide tailored packaged substation solutions. Based on the specific site conditions and project requirements, we can rationally configure the substation’s capacity, incoming and outgoing cable connections, and protection levels to meet the unique needs of each site.

Detailed description
The European-style prefabricated substation is a compact, fully enclosed outdoor electrical equipment that integrates high-voltage switchgear, dry-type or oil-immersed transformers, low-voltage switchgear, measurement and control systems, UPS backup power supplies, control transformers, protective and measuring devices, and indicating instruments—all housed within an enclosure boasting a high degree of protection. The substation features no external exposed components, with separate, independent compartments for the high-voltage room, low-voltage room, and transformer room. The transformer employs air-cooling for heat dissipation. This integrated outdoor substation offers advantages such as high safety and reliability, advanced integration, energy efficiency, environmental friendliness, intelligent monitoring and management, and flexible configuration options. It is particularly well-suited for applications in photovoltaic and wind power generation projects where special product requirements exist. Common capacities for dry-type transformers rated at 35 kV and below include 1,600 kVA, 2,000 kVA, 2,500 kVA, 3,150 kVA, 4,000 kVA, 5,500 kVA, 6,900 kVA, 7,400 kVA, and can reach up to 12,500 kVA at maximum.
| Safe and reliable The packaged substation is equipped with comprehensive electrical protections against overloads, short circuits, ground faults, and other electrical abnormalities. The transformer itself is fitted with non-electrical protections such as temperature, oil level, pressure, and gas monitoring. Moreover, the system enables real-time monitoring from the background and allows remote operation from the control center, ensuring the continuous safe operation of the equipment at all times. |
High integration After the factory completes prefabrication and the entire system has been integrated and debugged, it is transported to the site as a complete unit. At the site, only the high- and low-voltage cables and control/communication cables need to be connected before the system can be put into operation, thereby reducing on-site workload and improving construction efficiency. |
Energy-saving and environmentally friendly The transformer utilizes energy-saving and environmentally friendly materials, and its optimized design reduces no-load losses and enhances operational efficiency, meeting the national energy-saving standards for loss reduction. It also features an advanced cooling system that lowers operating temperatures, improves heat dissipation efficiency, and minimizes energy losses. |
Flexible configuration Whether it’s a photovoltaic power generation project or a wind power generation project, we can provide suitable packaged substation solutions. Based on the site conditions and project specifics, we’ll rationally configure the capacity of the packaged substation, its incoming and outgoing lines, protection levels, and other relevant parameters to meet the unique needs of each site. |
