Product Overview
KGVZ is a solid-dielectric automatic circuit recloser designed for overhead distribution lines and distribution substations up to 38 kV. The switchgear uses vacuum interrupters encapsulated in hydrophobic epoxy resin and a ganged magnetic actuator for three-phase opening and closing.
The operating mechanism is enclosed in a stainless-steel tank with a light-grey powder-coated finish. KGVZ15,KGVZ27, and KGVZ38 configurations cover 15.5 kV, 27 kV, and 38 kV voltage classes with 630 A or 800 A continuous-current options shown in the technical table.
The recloser is supplied with a BC300 or BC500 microprocessor controller for protection, control, monitoring, metering, event recording, and communications. Utilities, EPC contractors, distributors, and automation project buyers should provide the feeder study, protection settings, communication protocol, mounting arrangement, quantity, and destination for technical review and quotation.
The product guide states that the KGVZ series has been type-tested in CANGO‘s independent laboratory.
