Solid Automatic Circuit Recloser EPRIS/EPR-1, EPR-2, EPR-3
Entec's Single/Three-Phase Solid Automatic Circuit Reclosers(EPRIS/EPR-1, EPR-2, EPR-3) are designed for the application in overhead line and substation for voltage classes up to 15kV, 27kV, and 38kV.
The operating mechanism uses a permanent magnetic actuator that guarantees high reliability and maintenance-free operation. It uses vacuum interrupters encapsulated in epoxy bushings for arc quenching, eliminating the need for the insulants such as oil and gas.
The bushings are made of HCEP(Hydrophobic Cycloaliphatic Epoxy) that provides excellent insulation performance even under harsh climatic environments and polluted areas. The Recloser tank and control cubicle are made of stainless steel, which have strong endurance against hot, humid, dusty, or corrosive environment.
The Recloser is supplied with complete microprocessor-based controller(ETR300-R or EVRC2A-NT) including metering, monitoring, recording, and communication functions.
TThe Recloser has been fully type tested by accredited laboratories such as KEMA, CESI or KERI according to the international standard ANSI/IEEE C37.60 and IEC 62271-111.
