Important applications of insulting materials



1. Electric wiring in houses is made up of conductors made of copper or aluminium which are insulated with a covering of plastic,  rubber or some kind of varnished cotton.


2. Overhead conductors in the street for distribution of electricity comprise aluminium or steel- cored aluminium conductor and air between the conductor’s acts as insulator.


3. Electric iron comprises high resistance conducting wire for heat generation and mica or asbestos insulation is to prevent the flow of electric current in the outer body of the iron.


4. Electric fan comprises a single phase motor having copper winding on the stator varnished cotton acts as insulator.
