PRODUCT      DESCRIPTION
GN2-12(Z)box-type  fixed  AC meta-enclosed   switchgear  (referred  to  as"switchgear") is   suitable  for  three-phase  AC  single bus  with   rated voltage  of  36-12kV,50Hz,rated   current   of  630A 3150A.double   bus,single   bus  with  bypass   system,for acceptance  and  distribution  of power. It  can meet  the   use  requirements  of  various  types   of  power   plants,substations   and industrial   and mining   enterprises.
This  product  complies  with  the  national  standard  GB3906"3-35kv  AC  metal-enclosed switchgear",IEC298"AC   metal- enclosed   switchgear and    control   equipment",and  DU/T402,DL/T404 standard,and   meets    the  "five anti"lockout requirements.
The Technical Specifications of this XGN2-12 Switchgear define its electrical and mechanical parameters for medium-voltage power distribution applications. The Box Type Fixed Metal Enclosed Switchgear is suitable for three-phase AC single bus systems with rated voltage of 3.6-12kV, frequency of 50Hz, and rated current ranging from 630A to 3150A, accommodating double bus and single bus with bypass systems for acceptance and distribution of power. This 12kV AC High Voltage Switchgear meets the use requirements of various types of power plants, substations, and industrial and mining enterprises. The XGN2-12 Switchgear complies with the national standard GB3906"3-35kV AC metal-enclosed switchgear", IEC298"AC metal-enclosed switchgear and control equipment", and DL/T402, DL/T404 standards, and meets the"five anti"lockout requirements for enhanced operational safety. This Box Type Fixed Metal Enclosed Switchgear features rated short circuit breaking currents of 16, 20, 31.5, and 40kA, with rated short-time withstand currents matching these values. The 12kV AC High Voltage Switchgear offers power frequency withstand voltages between poles of 24, 32, and 42kV, and lightning impulse withstand voltages of 40, 60, and 75kV. Each XGN2-12 Switchgear ensures reliable power distribution in 12kV networks.
