27kV Outdoor Automatic Recloser
The 27kV outdoor automatic recloser serves 24kV three-phase overhead distribution lines (50/60Hz), compliant with IEC 62271-111 and benchmarked against IEEE C37.60. Widely adopted in South America, North America, East/South Africa, Southeast Asia, and Oceania where 24kV grids prevail. Available in three-phase ganged single-mechanism or three-phase independent mechanism configurations — independent mechanism is preferred for export projects. Upgraded insulation distances and vacuum interrupter sizing compared to the 15.5kV model. 304/316 stainless steel enclosure with outdoor powder-coat protection.
38kV Outdoor Automatic Recloser
The 38kV outdoor automatic recloser serves 33kV three-phase overhead distribution lines (50/60Hz), compliant with IEC 62271-111 and IEEE C37.60. The highest voltage class in the NAIJI recloser series, completing the 15.5kV / 27kV / 38kV sequence for global 11kV, 24kV, and 33kV grid coverage. Available in three-phase ganged or independent mechanism configurations. Significantly upgraded insulation distances, creepage distances, and vacuum interrupter sizing. 304/316 stainless steel enclosure with outdoor corrosion protection.
