Electrostatic Resistant Polymers and Insulated Polymers
Keywords:
Insulator, Insulating Polymer, Plastic, ResistanceAbstract
The electrically insulating polymer system resists the flow of electric current. A polymeric insulator has atoms with a bonded valence electron. It is used in parts of electrical equipment and is intended to support or separate electrical conductors without current passing through them. More materials, such as rubber-like chemical compounds and most plastics are also good insulators. They can insulate electrical wires, although they may have a weaker resistance. The simplest ceramic insulator is used in electric railways with an AC voltage of 25 kV, where the ideal polymeric insulator does not exist because insulators contain small numbers of mobile charges (charge carriers) where they can carry current. This is called the breaking potential of the insulator. Some materials such as glass, paper, and Teflon, which have high resistance, are considered very good electrical insulators as insulators for electrical wires and cables. Examples include rubber such as polymers and most plastics.
