An insulator is a solid material that does not allow the free flow of electric charges. It does not conduct current under the impact of high voltage electric fields. The manufacturers make it using materials that are poor conductors of current. The efficiency of an insulator is determined by how much resistance it provides to the current flow. You should buy reliable products from the porcelain insulators manufacturer in India for quality assurance.
Benefits of Using the Insulators
The technicians install electrical insulators in high voltage electric circuits and overhead cables. They serve innumerable purposes such as –
• It prevents the passing of high voltage current in a circuit
• It reduces the chance of electrical hazards
• It saves the environment by controlling the emission of pollutants
• It protects against electrocution or electric shocks
Important Properties of Electrical Insulators
• In the insulator, the valence electrons are held together tightly. There are no free electrons to conduct electricity.
• The material does not allow electric current to pass through it. This property is called electrical resistance. Its per unit cross-sectional area resistance per unit length is called resistivity. Therefore, insulators have high resistivity.
• Insulators have great dialectic strength. It is the maximum electrical field that the insulator can withstand. This happens without facing any breakdown.
• They have higher air permeability
Application of Electric Insulators
This equipment prevents the conduction of electrical charges. So, you can install and use it in the following areas –
· Circuit boards
· High voltage appliances
· Electric wire coatings
· Cable coatings
· Coatings of electric poles on the street
Types of Electric Insulators
• Pin type insulator
• Suspension type insulator
• Strain type insulator
• Shackle insulator
• Stay insulator
