1.Description
The HXGN and SM6 SF6 ring main unit is made up of modular units containing fixed, disconnectable orwithdrawable metal-enclosed switchgear, using sulphur hexafl uoride (SF6) or vacuum.
The HXGN and SM6 SF6 ring main unit are used for the MV section in MV/LV transformer substations in publicdistribution systems and MV consumer or distribution substations up to 36 kV.
2.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 flammable 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.
