High-Voltage Safety With Plastic Coating

Equipment, tools, and safety gear for working with high voltage need to be as reliable and protective as possible. That's where plastics come in, offering a durable, effective, non-conductive solution for many applications across the electrical industry. 

Choosing Plastic Coatings for High Voltage Use

Plastic coatings, whether applied by spraying or dipping, create a physical barrier that effectively stops electricity from traveling further, protecting adjacent parts and workers from coming into contact with the current. These dielectric, or insulating coatings typically include plastisol dip coating and epoxy, nylon, and vinyl powder coatings. 

Advantages of Plastic Coatings for High Voltage Applications

Powder and dip coating treatments are a natural match for electrical parts and equipment, providing numerous benefits, including:

Effective Insulation

Naturally dielectric, plastic coatings can prevent unwanted contact between parts and with environmental factors, including protecting high-voltage parts from:


  • Dust, dirt, and debris
  • Water and moisture
  • Chemical exposure
  • Other conductive parts
  • People and animals

Improved Safety

Whether it's plastisol-coated tools and PPE or coated bus bars, tap connectors and other components, plastic coatings keep workers safer and help prevent such hazards as arcs and shorts. Soft, rubbery plastisol coatings can also make high-voltage tools and their users easier to see in low-light conditions and make things easier to grip in wet or hazardous conditions.

Enhanced Durability

Plastic coatings for electrical applications can range from thin powder-coated films around 1/100th of an inch to thick plastisol dip coating around ¼-inch in thickness. The electrostatic bond and heat curing of powder coating and the natural qualities of plastisol make both types of coatings extremely resilient, protecting high-voltage parts and tools from impacts, abrasions, and other damage.
