Electrical insulation Materials

Any elemental discussion of electrical insulation should properly take into account the prime function of an electrical insulating material and the peculiar properties which distinguish these materials from the myriad material substances now available to modern man. At the turn of the century, this was a relatively simple task. Today, the insulation specialist is confronted with a host of insulating materials — many the product of modern polymer chemistry. From these materials he must select the right insulating material for a particular job. This is no easy task. It underscores anew the necessity of understanding the fundamental function or functions of electrical insulating materials when used in specific electrical apparatus.
