OverviewOperating principleBrief historyDesign featuresGenerator circuit breakersHigh power testingIssues related to SF6 circuit breakersComparison with other typesCurrent interruption in a high voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF6), having excellent dielectric and arc quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF6 gas is electronegativeand has a strong tendency to absorb free electrons. The contacts of the brea…

2020/4/19Insulation effectiveness is measured by its thermal resistance value, or R value, a number between 1 and 60 that reflects the material's resistance to heat transfer. The better the insulation, the higher the R value. This number is determined by the type of insulation, its thickness, density, and where and how the insulation is installed.
