Japan, Dec. 2 -- Toshiba Energy Systems & Solutions Corporation (Toshiba) has commercialized a gas-insulated busbar (GIB) that completely eliminates the use of sulfur hexafluoride (SF6), a highly potent greenhouse gas, and instead uses natural-origin gases. The newly developed GIB supports rated voltages of up to 550 kV, and is designed to advance sustainable power infrastructure by significantly reducing environmental impact. The GIB is now available to order.GIBs are core components of substations, used to connect transformers, switchgear and transmission lines, and transmit power between them. Similar to other power transmission and distribution equipment, GIBs use a high-insulation gas contained under high pressure within a hermetically...
