Prefabricated Substation (Hua-style)

The Hua-style prefabricated substation is an integrated outdoor power transformation device that combines high-voltage switchgear, oil-immersed transformers, low-voltage switchgear, monitoring and control systems, UPS backup power, control transformers, measurement and protection components, and indicating instruments within a high-protection-level enclosure. The transformer uses cooling fins for heat dissipation. It features safety, reliability, high integration, energy efficiency, environmental friendliness, intelligent monitoring and management, and flexible configuration. It is suitable for applications such as photovoltaic power generation and wind power generation. Commonly used transformer capacities for 35kV and below include 1600kVA, 2000kVA, 2500kVA, 3150kVA, 4000kVA, 5500kVA, 6900kVA, and 7100kVA, with a maximum capacity of up to 12500kVA.
