GIS SF6 model HXGN15 series Switchgear 12/24/36KV 630A 1250A M.V panel GB ISO
Product Introduction
General
The so-called "ring network cabinet" means that each distribution branch is equipped with a switch cabinet (outgoing switch cabinet), and the busbar of this switch cabinet is also a part of the ring trunk. In other words, the ring trunk line is composed of the bus bars of each outlet cabinet. Each outlet cabinet is called a "ring network cabinet". In fact, if you take out a ring network cabinet alone, you can't see the meaning of "ring network".
