The YB□-12/0.4 pre-installed substation, also known as a high-voltage/low-voltage prefabricated substation or European-style substation, is an integrated movable power distribution unit. It is composed of high-voltage and low-voltage switchgear, transformers, and an outer casing, pre-assembled in a factory. This type of substation is designed to replace traditional civil-constructed substations, providing the same power distribution functionalities.

Key features include:

• Usability in both indoor and outdoor environments.
• Applications across various sectors such as industrial parks, residential areas, commercial centers, public spaces, airports, ports, mining fields, oil fields, and temporary construction sites for receiving and distributing electrical power.
• Standardized and customizable design in line with national grid requirements, ensuring safety, reliability, durability, uniformity, interchangeability, and scalability.

The design follows the technical specifications outlined by the State Grid Corporation of China for 10kV high-voltage/low-voltage prefabricated substations, ensuring that the product meets modern standards for a high-efficiency, reliable distribution network.
