Cable Insulation TechnologiesCable Insulation ComponentsQualityHVDC CableCable TerminalsCable JointsX Ray CableTesting of High Voltage CablesSee AlsoReferencesLike other power cables, high voltage cables have the structural elements of one or more conductors, an insulation system, and a protective jacket. High voltage cables differ from lower voltage cables in that they have additional internal layers in the insulation system to control the electric field around the conductor. These additional layers are required at 2,000 volts between conductors.

The higher the voltage (i.e. volts/meter) the higher the pressure can be for a discharge.

Environmental ConcernsSafety ConcernsSpecial Handling ProceduresInstallation ConcernsOperation and Maintenance ConcernsEnd of Life and Recycling ConcernsThe insulating gas used in MV GIS switchgear,sulfur hexafluoride (SF6), is a highly potent greenhouse gas with a global warming potential 23,900 times greater than CO2. SF6 also has an atmospheric life of 3,200 years, so it will contribute to global warming for a very long time.

A Strain gauge (sometimes refered to as a Strain gage) is a sensor whose resistance varies with applied force; It converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured. When external forces are applied to a stationary object, stress and strain are the result.
