Solid recloser

Your position:Home > Main Products > Solid recloser >
Rockwill Electric strives to bring our customers the latest technology and competitive pricing and best service for distribution automatic.
The solid recloser series automatic circuit reclosers can use on overhead distribution lines as well as distribution substation applications for all voltage classes 15kV up to 38kV at 50/60Hz power system per standards like: IEC62271-111,ANSI/IEEC C37.60 and GB1984-2006. And All Rockwill’s Recloser is provided with current rating up to 1250A.
The solid recloser series automatic circuit reclosers integrates the functions of control, protection, measurement, communication, fault detection, on-line monitoring of closing or opening.
The solid recloser series vacuum recloser is mainly combined with integration terminal, current transformer, permanent magnetic actuator and its recloser controller.
The vacuum recloser tanks are manufactured from 304 grade stainless steel and are powder coated a light grey colour.
Whole recloser tank meet to IP65 protection class, equipped with a auxiliary plug to connect with recloser controller by control cable, Diameter Max58mm, standard 6 M length(9M for special).
Primacy incomer terminal(directly connect to interrupter reduce power lost) Current transformer(external modular design easy for quality control and maintenance)
Vacuum interrupter(Adopt the APG technology with external silicone rubber mold pressure covering, increasing the whole insulation and weathering performance)
