Home/Outdoor High-Voltage Switchgear/Automatic Circuit Recloser/38kV Medium Voltage Electrical Three Phase Recloser In Power System 38kV Medium Voltage Electrical Three Phase Recloser In Power System
The LYVZ38 three-phase recloser series is our top-rated outdoor automatic recloser solution for up to 38kV systems. Featuring 170kV lightning impulse withstand, ultra-long creepage distance (1290mm), and high breaking current up to 40kA, it’s designed for critical power infrastructure.
The magnetically ganged actuator ensures fault clearing across all three phases. Coupled with intelligent control from BC500, the medium voltage recloser provides comprehensive monitoring, protection, and adaptive reclosing, supporting grid reliability and reduced outage times.
Its manual open design and visual status indicator increase operator safety during on-site switching or inspection.
