The ZW32-40.5kV outdoor vacuum recloser is a three-phase AC 50/60Hz high-voltage switchgear designed for medium-voltage power distribution systems in urban and rural areas. It can automatically detect and clear transient faults such as lightning or temporary line contact, while isolating permanent faults to maintain network stability and reduce outage areas. This ensures continuous power supply and reduces operational costs by minimizing on-site maintenance.
Equipped with advanced solid insulation technology, the recloser integrates vacuum interrupters and multiple sensors within an epoxy resin and silicone rubber insulated pole. The intelligent controller, compliant with IEC 61850, enables remote monitoring, control, and automation, making it an essential device for modern smart grid applications.
