YBM Series Prefabricated Substation for Residential Communities-6 to 40.5kV

The YBM series products represent a highly integrated power distribution solution, meticulously assembling medium-voltage (MV) switchgear, transformers, and low-voltage (LV) distribution equipment based on pre-defined connection schemes. Engineered for versatility, this series of substations is ideally suited for diverse applications, including residential communities, hotels, large-scale construction sites, and high-rise buildings.

It operates efficiently within voltage ranges of 6kV,12kV, 24kV and 40.5kV, at a frequency of 50Hz, and can handle capacities of up to 2500kVA.Adhering to stringent international standards, the YBM series complies with IEC 60076-1 and IEC 62271-202. It also meets the requirements of ANSI/IEEE C57.12.00, C57.12.20, and C57.12.90, as well as BS171 and SABS 780 (certification available upon request), ensuring reliable performance and quality assurance across various regions and industries.

Structure Characteristics

• Our box-type transformer substations come in two distinct configurations: corridor-style and non-corridor-style. The frames are constructed from high-quality anti-corrosive steel through welding, while the bases are made of hot-galvanized steel. The compact design significantly reduces the substation footprint, making it ideal for urban environments where space is at a premium.
• Each box-type transformer substation consists of three compartments: the high-voltage (HV) cabinet, the low-voltage (LV) cabinet, and the transformer cabinet. The internal layout can be tailored to specific customer needs. The double-layer roof design features an air-filled cavity, which provides effective insulation against temperature increases.
• These substations rely on natural convection cooling as the standard option. However, forced air cooling and automatic anti-condensation heaters can be added as optional enhancements. To safeguard the transformer, various combinations of load switches and fuses are available.
• They support multiple power supply modes, including terminal power supply, ring power supply, and dual power supply. The LV cabinets have a welded structure and are equipped with clear and durable nameplates. Additionally, the cabinets are securely bolted to the tank for stability.
