IS 11 High Voltage Switchgear - Gluckman Consulting· PDF fileIn the switchgear sector, the F-Gas Regulation affects the use of SF 6 as an insulating gas in various types of high voltage equipment. The 2014 EU F-Gas Regulation replaces the 2006 Regulation, strengthening all of the 2006 requirements and introducing a number of important new measures.
Insulator (electricity) - Wikipedia of conduction in solids. Electrical insulation is the absence of electrical conduction.Electronic band theory (a branch of physics) dictates that a charge flows if states are available into which electrons can be excited. This allows electrons to gain energy and thereby move through a conductor such as a metal.If no such states are available, the material is an insulator.
