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.
