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.
Transformer Insulating Oil - Transformer Insulation System Insulation System. Each transformer has its own complex system of insulation. There always must be a combination of solid and fluid (or liquid) insulating components. There is a plenty of possible insulating materials, but there are also the most common types. Transformer insulation can also have major and minor insulation.
Electrical substation - Wikipedia substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.
