Recloser with Directional Relay (Solid)


The Joongwon Recloser is designed to meet increasing requirement of the electric utility industry, providing a safe, maintenance free, long life, economical device to perform fault current interrupting and reclosing on overhead distribution lines. The Joongwon Recloser is applicable to 12kV(max.15kV), 24kV(max.27kV) and 36kV(max.38kV) power distribution systems and substation. It can be operated manually(if applicable) or electrically via controller with FTU and should be mounted to the pole and substation mounting base.
The Joongwon Recloser is able to meet present recloser demands, plus offer advanced capabilities such as fault location, adaptive protection, control monitoring, power quality, communications, single phase tripping and loop control for tomorrow’s needs of power distribution line.
