72.5kV, 126kV, 145kV GIS(SF6 gas insulated switchgear)

Product Description

ZF****2.5/**6/**5 SF6 gas insulated switchgears (GIS) is three-phase enclused in a common Al enclosure GIS with excellent electric&mechanical performance and compact construction. It is widely used in the power grid ranging from *2.5kV up to **5kV. Main features: Large breaking capability Self-energized arc control device is applied for circuit breaker. The device is so designed that the energy of arc generated is used to improve its arc quenching capability, which leads to a higher breaking capabilit and a lower operating force needed. Spring&motor operating mechanism The circuit breaker and high speed disconnector and earthing switch are equipped with motor drive, spring charged mechanism while maintenence disconnector and earthing switch are equipped with motor xxxxx greatly improve GIS’s operation reliability. Compact construction All electric components, xxxxx circuit breaker, disconnector, earthing switch, CT, PT, lightning arrestor are three-phase enclosure type to ensure compact construction. Easy erection&maintenace The complete bay of GIS will be delivered without dismantlement. Only connection between different bays of GIS is only to be needed to realize easy site erection. Double sealing gaskets and rings etc are adopted to realize maximum 0.5 gas leakage per year.
