There are some materials, such as paper and glass, are the very best insulators. All of them are superb for insulation of cables and electrical wiring and also, used as a whippy covering on them.High- voltage power lines usually use only air, because steady and firm coverings are not practical. Insulator - it's such device for electrical and mechanical connection betwixt of electrical device's parts, that is under different electrical potentials. Insulator consists ofdetails of its bending (fittings) and dielectric (that is insulator itself). Sizes and construction of insulators are defined with the help of conditions of its exploitation and electrical voltage of installations, mechanic loads. High voltage glass insulators of open sub-distributing devices and power lines of electrical stations and substations open for influenceof atmospheric condensations, but they are especially dangerous while strong pollutions of the environment and air.In order to increase voltage in such insulators flashover ( electrical discharge on surface) outer surface gets more difficult shape,it helps to make the way of discharge more longer. Glass insulators are created from unique strained glass, besides, they have high mechanic durability, and their weight and size is more less than other insulators made of porcelain. They have only one disadvantage, there is a small electric resistance. Glass insulators value is that they definedby the voltage of electric field (kV/m), with which material of the insulator losses its dielectric qualities, give enough electric durability, also, they have plenty decent mechanic durability, that's why it allows the possibleness to resist to dynamic efforts, which arise between separate current-conducting parts during short closing in a circuit, they provide permanence of their qualities under the influence of environment (snow, rain and etc), they have enough heat resisting, it means they donot alter their electrical qualities in time when temperature changes in certainlimits, their surface is steady for the effect of electric charge. Glass insulators for sale and installation is not the only one where they can be used, on occasion they can be used in collecting as very popular objects. They can have different shapes, sizes, prices and colours. They are resplendent for display and have priceless historic interest.There are some materials, such as paper and glass, are the very best insulators.

High voltage glass insulators of power lines and open sub-distributing devices of substations and electrical stations open for workof atmospheric condensations, but they are especially dangerous while substantial pollutions of air and the environment. Glass insulators are made of specialized strained glass, besides, they have high mechanic durability, and their weight and size is more less than other insulators made of porcelain. Glass insulators value is that they definedby the voltage of electric field (kV/m), with which material of the insulator losses its dielectric qualities, supply enough electric durability. Glass insulators for sale and installation is not the only one where they can be used, even they can be used in in very popular collecting.
