HV Switchgear
XGN-12 Solid-insulated Switchgear
12kV epoxy-cast solid-insulated switchgear for high altitude, cold and polluted areas.
XGN-12 is a solid-insulated metal-enclosed switchgear for 12kV systems. The main conductors are encapsulated in epoxy resin as a whole, providing full insulation, full sealing, full shielding and maintenance-free operation — especially suitable for high altitude, severe cold, humid and heavily polluted regions.
