Introduction 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 12(max.15)kV, 24(max.27)kV, 36(max.38)kV 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.



Features - Proven design rated for 10,000 full load operations - Hydrophobic Cyloaliphatic Epoxy (HCEP) insulation provides industry leading reliability - Air insulation for an environmentally friendly design - Minimal maintenance required for the high voltage unit - Web Human Machine Interface (web HMI) software for field configuration - Remote Communication : MODBUS, DNP3.0, DNP3.0 over TCP/IP, IEC 60870-5-101, IEC 60870-5-104 over TCP/IP



Recloser Design



• • •



Magnetic actuator : 10,000 full load operations Vacuum interrupters : Lasting quality with 10,000 full load operations Pole assembly - UV protected for environmental durability - Molded design reduces risk of tampering



• HCEP insulating material - The Recloser insulating material is Hydrophobic Cycloaliphatic Epoxy(HCEP). Hydrophobic means resistant to water. This capability is advantageous because it prevents water from developing completely wetted, resistively conductive surfaces on outdoor insulation.
