After installation of transformer on the plinth, accessories viz. radiators, headers, bushings, air blowers, oil pumps with connecting pipes, OLTC drive mechanism and the connecting pipes to diverter switch compartments, marshalling box, etc. have to be mounted on the transformer as per the manufacturers' drawings.
Products - SF6-gas Gasbanor (Switzerland) GmbH, Micafluidgasbanor.com/english/products.htmProducts SF6-gas. Sulfur Hexafluoride is a colorless and odorless gas. SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons. It has over 100 times better arc quenching capability and significant better heat dissipation than air (N 2).
