11kv Switchgear Description   XGN series ring main unit are applicable for Mining Enterprise, residential building, high-rise buildings and schools, parks and so on power distribution system. It is used as AC three-phase 10KV,50HZ ring main power supply units and terminal power distribution device. It can be used in the system of 50HZ,3.6-12kV and making and breaking of load current and short-circuit current ,controlling and protecting.    Normal operating conditions  Ambient air temperature:
1) less than or equal to 40°C
2) less than or equal to 35°C on average over 24 hours
3) greater or equal to –5°C.
Altitude
1) less than or equal to 1000 m
2) above 1000 m, a derating coeffi cient is applied (please consult us).
Solar radiation
1) no solar radiation infl uence is permitted.
 Ambient air pollution
1) no signifi cant pollution by dust, smoke, corrosive and/or fl ammable gases,
vapours or salt.
 Humidity
1) average relative humidity over a 24 hour period, less than or equal to 95%
2) average relative humidity over a 1 month period, less than or equal to 90%
3) average vapor pressure over a 24 hour period, less than or equal to 2.2 kPa
4) average vapor pressure over a 1 month period, less than or equal to 1.8 kPa.
For these conditions, condensation may occasionally occur. Condensation can be
expected where sudden temperature changes occur in periods of high humidity.
To withstand the effects of high humidity and condensation, such as breakdown of
insulation, please pay attention on Civil Engineering recommendations for design
of the building or housing, by suitable ventilation and installation.   Thechnical Data
