Prefabricated Substation (Hua-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 a central control room, 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, all that’s required is connecting the high- and low-voltage cables as well as the control and communication cables to put the system into operation—thus significantly reducing on-site workloads 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. Additionally, an advanced cooling system is employed to lower operating temperatures, improve heat dissipation efficiency, and reduce energy losses. Flexible Configuration: Whether it’s for photovoltaic power generation or wind power projects, we can provide tailored packaged substation solutions. Based on the specific site conditions and project requirements, we’ll 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 Huashi prefabricated substation is a type of outdoor substation in which high-voltage switchgear, oil-immersed transformers, low-voltage switchgear, measurement and control systems, UPS backup power supplies, control transformers, protective and measuring components, and indicating instruments are all integrated and installed within an enclosure featuring a high degree of protection. The transformer utilizes heat sinks for cooling, making it a fully integrated outdoor substation device. It boasts features such as safety and reliability, high integration, energy efficiency and environmental friendliness, intelligent monitoring and management, and flexible configuration. This substation is suitable for applications including photovoltaic power generation and wind power generation. Common transformer capacities for 35 kV and lower systems include 1,600 kVA, 2,000 kVA, 2,500 kVA, 3,150 kVA, 4,000 kVA, 5,500 kVA, 6,900 kVA, 7,100 kVA, and can be configured up to a maximum capacity of 12,500 kVA.
Safe and reliable The packaged substation is equipped with comprehensive electrical protection features, including overloading, short-circuit, and ground-fault protection. The transformer itself is fitted with non-electrical protection devices such as temperature, oil level, pressure, and gas monitoring systems. Moreover, the system enables real-time monitoring from the background and 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, all that’s required is to connect the high- and low-voltage cables and the control and communication cables, enabling immediate operation—thus 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. |
