II. Description
The HXGN ring main unit is made up of modular units containing fi xed, disconnectable orwithdrawable metal-enclosed switchgear, using sulphur hexafl uoride (SF6) or vacuum.
The HXGN 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.
HXGN units are designed for indoor installations. Their compact dimensions are:
A. 375 to 1500 mm width
B. 1600 to 2250 mm height
C. 840 to 1400 mm depth
This makes for easy installation in small rooms or prefabricated substations. Cables are connected via the front.
All control functions are centralised on a front plate, thus simplifying operation. The units may be equipped with a number of accessories (relays, toroids, instrument transformers, surge arrester, control and monitoring, etc. ).
