European Prefabricated Outdoor Transformer Box Substation

LiuGao stands as a dedicated European type substation manufacturer,YB series European Prefabricated outdoor transformer box substation employs new technology, advanced components, and high-low voltage automation to address the power distribution automation needs of the high voltage 12KV and the intelligent community property management requirements of the low voltage 0.4KV. The upper monitor, located in the central station or property management department, facilitates four-remote system management. By connecting multiple intelligent box substations in a "hand-in-hand" ring network and utilizing autonomous software, the system achieves automatic location, fault clearance, load shifting, and network reconfiguration in the fault section. This ensures the recovery of power transmission within one minute.

Product Description

Liugao is European Prefabricated Outdoor Transformer Box Substation supplier.YB□-12/0.4 series of prefabricated substations integrate high voltage electrical equipment, transformers, and low voltage electrical equipment into a compact and complete power distribution device. These substations are employed in various settings, including urban high-rise buildings, residential areas, high-tech development zones, small and medium-sized factories, mines, oil fields, and temporary construction sites, to receive and distribute electric energy within the power distribution system.

Key features of the YB□-12/0.4 series prefabricated substations include a robust set of equipment, compact structure, safe and reliable operation, convenient maintenance, and portability. Compared to conventional substations, these box-type substations with the same capacity typically occupy only 1/10 to 1/15 of the space, significantly reducing design workload, construction complexity, and overall costs. They are suitable for use in ring network distribution systems, dual-power systems, or radiation terminal distribution systems within the distribution network. YB prefabricated substations adhere to the national standard GB/T17467-1998 for "high-voltage/low-voltage prefabricated substations."
