Standard Insulating Materials Used in Electrical Engineering.

Electrical technology incorporates many different types of insulating materials for safety against electrical hazards. Materials like PVC, glass, asbestos, rigid laminate, varnish, resin, paper, Teflon or rubber are very good electrical insulators. These materials can insulate electrical conductors from electric charge. Best remedy to safeguard individuals from electrically energized wires and parts is through insulation. This articles covers why electrical insulation is needed, the application of insulation for cable and transmission lines (power lines), circuit boards, power stations and substations, home appliances, PPE, and insulation mats, and provides a list of common insulating materials and ASTM material standards.
