12kV SINGLE POLE OUTDOOR AUTO RECLOSER
SRIWIN ELECTRIC, an ISO 9001:2015 Certified company, offers 12kV Single pole outdoor Auto Recloser suitable for outdoor pole mounting. Auto Recloser used on overhead distribution system to detect and interrupt transient/momentary faults. Since many short circuits on overhead lines clear themselves, an Auto Recloser improves service continuity by automatically restoring power to the line after fault hence Auto Recloser act as outdoor distribution switchgear.
