The dielectric strength of a material is a measure of the electrical strength of an insulator. It is defined as the maximum voltage required to produce a dielectric

REI - A European rating that describes three basic criteria for fire resistance as REI and these are defined as: R = load bearing (capacity to provide structural stability) E = integrity (capacity to remain intact) I = insulation (capacity to maintain a defined temperature on the unexposed side of the building element).

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. 2020-09-03 · The voltage operating capacity of the insulator is from 11 kV to 765 kV. It is mostly used in the overhead transmission system or line. It provides more flexibility to the overhead line. To state that an insulation material can withstand up to 130°C RTI means that under electric or mechanical stress, after 60 000 hours the product will have kept at least 60% of its initial characteristics.
