Electrical Insulation

Electrical Insulation

Electrical insulation can be provided by materials that facilitate an electric isolation of two parts at different voltages. Electrical insulation coatings are also known as dielectric coatings. Today, electrical insulation coatings are not only widely used for the electronics and electrical engineering industry but they are in high demand in growing industries such as vehicle engineering and machinery engineering.

A&A Coatings | Thermal Spraying Process to Achieve Electrical Insulation

When it comes to materials engineering, A&A Coatings has been recognized as one of the industry leaders because over the years, we are able to develop high quality dielectric coatings via our thermal spraying coating processes. The common materials used for the thermal spraying processes to achieve electrical insulation include oxide ceramics and polymers – ceramics are better than polymers due to their provision of higher corrosion resistance and wear resistance as well as longer durability. This is also why we tell our customers that ceramic insulation coatings are always worth the investment.

Benefits of Electrical Insulation Coatings

Obviously, the main advantage of dielectric coatings is their ability to provide electrical resistivity. Generally, electrical insulation coatings are able to provide these other benefits:

  • Good moisture protection
  • Good track resistance
  • Good corrosion resistance
  • Good abrasion resistance
  • Prevent electrical leakages and short circuits

Common Parts That Need Electrical Insulation Coatings

Engine components, crimper wheels, cable channels, corona rolls, circuit parts, and rolling contact bearing shells are some of the most common parts that can benefit from our electrical insulation coatings.

A&A Coatings has been an industry frontrunner in providing dielectric coatings for different applications. When you opt for our thermal spraying expertise, you will experience coatings that have high dielectric strengths up to 2kV/mil and they will also feature ultra high bond strength.
