Descripton

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 fixed connection schemes. Engineered for versatility, this series of substations is ideally suited for diverse applications, including neighborhood utility units, hotels, large-scale construction sites, and high-rise buildings. It operates efficiently within voltage ranges of 12kV, 24kV, 36kV, and 40.5kV, at a frequency of 50Hz, and can handle capacities of up to 2500kVA.

Adhering to stringent international standards, the YBW series complies with IEC60076 and IEC1330, as well as the ANSI/IEEE standards C57.12.00, C57.12.20, and C57.12.90. Additionally, it meets the requirements of BS171 and SABS 780, 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.
  

• 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 air cooling as the standard option. However, forced air cooling and automatic anti - condensation equipment 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 screen - type nameplates. Additionally, the cabinets are firmly fastened to the tank for stability.
