General:
XGN66A-12 Cubicle Fixed AC Metal-clad Switchgear is a lastest version of high voltage complete set of electric
apparatus for satisfying national standard GB3906 " 3-35kV alternative current metal-clad switchgear" and
specifications of DI404 "indoor alternative current high voltage switchgear ordering specifications" issued by
Ministry of Electricity Power, as well as IEC 298 "Above 1kV to 52kV alternative current metal-clad switchgear
and control-switchgear specification".And it has 5-
Protective functions:
This switchgear is a kind of the indoor complete set apparatus with 3-10kV three phase alternative current 50Hz
single busbar segment, used for power transmission and distribution, and meanwhile having controlling,
protecting and monitoring functions.It is used in places, such as power plants, substations, industrial and mining
enterprises, high buildings, etc.And it can be combined with ring main unit used in some substations.
Product Features:
1.A series of vacuum circuit breaker, such as degrees of 23kV, 3150A, 40kA, etc.Could be fitted with.
2.A kind of specified designed switchgear in order to reduce occupied area of substation.
3.Combination with ring main unit.
4.Simple structure but reliable machinery interlock for antierror operation, ad operation is easy.
5.Each functional compartment is separated, which can effectively resist trouble to expand with individual
pressure release passage.
6.Insulation distances and cable terminal contact could be watched through watching window.
