Detailed information about the YBW prefabricated outdoor substation.
1. Product Introduction
Outdoor prefabricated substationYBW series (European type). It is a compact integrated power distribution unit designed to replace traditional civil substations with rapid deployment, high efficiency, safety, reliability, and cost savings.
The system includes high-voltageswitchgear, distributiontransformers, low-voltage switchgear, measuring instruments, reactive power compensation systems, intelligent monitoring systems, lightning protection, and moisture-proof systems. All assembly, electrical installation, testing, and commissioning work is completed at the factory. On-site, only foundation laying, cable connection, and grounding are required, significantly reducing construction time and costs.
The fully sealed and anti-corrosion housing ensures stable operation in harsh environmental conditions: high temperatures, cold, humidity, dust, and coastal salt spray. The substation supports flexible adjustment of voltage, power, protection level, and power supply mode (terminal, ring, dual-channel).
