Why Bus Bar Coatings Matter

What Are Bus Bars?

Bus bars, or busbars, are metal strips or rods, typically made of copper, brass, or aluminum, which connect parts of electrical distribution systems. While small bus bars are used in a variety of electronics, larger bus bars are a vital component of both low- and high-voltage environments, including power generation applications, aluminum smelters, electric vehicles, electrical service panels, switchyards, generators, charging stations, and battery banks. Systems of bus bars are commonly used to supply power in facilities such as factories and hospitals.

Importance of Bus Bar Coatings

Efficient conduction is a vital part of any electrical system, and coating bus bars can help maintain them at their peak ability to conduct current. Many powder and dip coatings are suitable for electrical applications, although epoxy, vinyl, and plastisol are most commonly used to protect bus bars for:

Corrosion and Oxidation Risks

Corrosion and oxidation can reduce the ability of a bus bar to efficiently do its job by increasing its resistance and even contributing to possible overheating and system failure. Powder coating on bus bars can protect them from exposure to air, moisture, and other contacts which contribute to oxidation and corrosion. 

Safety Hazards

Particularly in high-voltage environments, bus bars can carry substantial electrical loads. Coating, especially with plastisol, can make them safer, especially for workers around them. Coatings can also help prevent arcing and short circuits, and minimize buildup of dust and debris.
