Detailed information about the YBW prefabricated outdoor substation.
1. Introduction to the product
Outdoor prefabricated substationThe YBW series (European type) is a compact, integrated power distribution system designed to replace traditional civil substations thanks to its rapid deployment, high efficiency, safety, reliability, and cost savings.
The system includes high voltagedistribution devices, distributiontransformersLow-voltage switchgear, measuring instruments, reactive power compensation systems, intelligent monitoring systems, lightning protection, and moisture protection systems. All assembly, electrical installation, testing, and commissioning work is performed at the factory. On-site installation requires only foundation laying, cable connections, and grounding, significantly reducing construction time and costs.
The fully sealed and corrosion-resistant enclosure ensures stable operation in harsh environmental conditions: high temperatures, cold, humidity, dust, and coastal salt fog. Substationsupportsflexible adjustment of voltage, power, degree of protection and power supply mode (terminal, ring, two-channel).
