66/77 kV class SF{sub}6 gas insulated transformers

摘要

SF{sub}6 Gas Insulated Transformers have the superior characteristics, high reliability, high safety, easy maintenance and so on. So they have been much used as 66/77 kV class substation equipment.Nissin has compacted 66/77 kV Class Gas Insulated Transformers and fitted them in "All-in type Substation Equipment", due to design the optimum structure of the insulating and cooling systems.This article describes the outlines of the above results.
