Description
The flanges are adapted to the customer's transformer and GIS, so the bushing is selected for a specific pair of equipment. One side operates in the tank oil, the other in the GIS SF6. The insulation is dry, RIP or RIS. Direct connection removes the overhead busbars between transformer and switchgear. The bushings comply with IEC 60137 and IEC 62271-211.
