GSS4 12kV Solid Insulated High Voltage Switchgear With Metal Enclosed HV GIS Switchgear
GSS4 Solid Insulated Metal Enclosed Switchgear,High Voltage Switchgear
1. Overview of GSS4 Solid Insulated Metal Enclosed Switchgear,High Voltage Switchgear
GSS4-12 series of solid-insulated metal-enclosed switchgear is an indoor three-phase AC 50Hz, rated voltage of 12kV, suitable for secondary power distribution systems, with a rated current of 1250A. GSS4 is a new type of medium voltage switchgear that uses solid insulating materials as the insulating medium of the main conductive circuit. The functional components of the main conductive circuit are encapsulated with solid insulating medium into one or several fully insulated and fully sealed modules, which can be combined or combined again. Expansion, the solid insulation cabinet can replace the SF6 ring main unit, and it is the preferred equipment for the smart grid construction as the ring main unit.This switchgear meets GB, DL and other standards.
