Fenarro's YB-40.5/zkV Prefabricated Substation represents a revolutionary approach to medium-voltage power distribution. This fully integrated, factory-assembled, and tested solution is designed for 35kV three-phase AC 50Hz systems, encapsulating primary and secondary equipment within a robust, transportable enclosure. Engineered for durability, the enclosure is sealed against moisture, dust, and corrosion, ensuring reliable operation in diverse and challenging environments from coastal areas to arid industrial zones. By moving up to 80% of the assembly and testing work to our controlled factory environment, Fenarro drastically reduces on-site installation time, labor costs, and project risks, enabling faster grid connection and commissioning.
Rapid Deployment: Significantly reduces field construction time from months to weeks.
Superior Protection: Welded steel structure with IP54 rating, resistant to harsh weather and environmental conditions.
High Safety: Full segregation of compartments, equipped with safety interlocks and emergency systems.
Smart Ready: Pre-wired for seamless integration with SCADA, remote monitoring, and IoT platforms.
Quality Assured: 100% factory tested in accordance with GB/T17467-2020 and DL/T537-2018 before shipment.
Customizable: Layout and equipment can be tailored to specific project requirements (e.g., transformer type, switchgear brand).
