CV Self-Sealing Valve
This product is a device connecting SF6 gas density monitor meter or density meter and SF6 gas chamber; after the completion of the assembly, SF6 gas chamber can be effectively sealed. It can be applied to high and medium voltage equipment.
Application of CV Self-Sealing Valve
SF6 Gas Insulated Switchgear (GIS)
SF6 insulated circuit breakers
SF6 insulated pole-mounted switch
SF6 insulated transformer
SF6 insulated mutual inductor
SF6 Gas insulated busbar systems
SF6 insulated inflatable cabinet
SF6 insulated RMU
Feature of CV Self Sealing Valve
Self-sealing: If the device or connector is removed, self-sealing can be done
It can be used repeatedly
