Micah, often used as insulation, is predominantly utilized between commutator bars. In electrical applications, commutator bars are part of electric motors and generators, where they play a crucial role in converting alternating current (AC) to direct current (DC). The insulation provided by micah is essential to prevent short circuits and ensure efficient operation, as it can withstand high temperatures and electrical stress.

This property of micah makes it particularly suitable for environments where electrical conductivity could be detrimental to the performance of the equipment, allowing for safe and reliable operation of the machinery. The use of micah insulation helps enhance the duration and reliability of electrical components by preventing electrical arcing and ensuring proper functioning.
