Copper Busbar Coatings FAQs

Copper Conductors

Coating Systems can coat equipment or products essential to your industry. One of the many products that we can coat are copper busbars.

Discover answers to some frequently asked questions about copper busbar coating in our educational blog.

What are copper busbars?

Busbars are groups of conductors that collect and distribute electricity. It can have multiple joints and connectors that feed electrical power to various parts of a system. The part of the system where a busbar is located acts as a central hub for power to flow through.

Copper busbars are metallic strips made from copper that ground and conduct electricity. Copper busbars are preferred over other metals because they are light, soft, and malleable and boast a high thermal and electrical conductivity. Its resilience provides extra security in case of shorts or high-temperature situations.

Copper busbars can be found in just about any industry, including factories, hospitals, schools, and electrical substations. Busbars can move power between floors or different sections of a building, as well as moving electricity from a battery bank or similar facility to an electrical circuit.

What are the uses for copper busbar coating?

Without proper coatings, these hubs of electricity would not last as long as we need them to due to the high amount of electrical traffic that flows through their conductors. A faulty busbar can be disastrous for a facility, so having experts apply a powder coating to your copper busbars can ensure they last longer and act more effectively.

Preventing rust on the copper is essential for electrical conductivity, so a powder coating can provide anti-corrosive properties to your busbars. As electrical systems are made up of multiple different types of metals, when these metals come into contact through an electrical current a process known as galvanic corrosion occurs. The conduction of electricity can cause one of the metals to begin to corrode, but powder coating can reduce the amount of galvanic corrosion that occurs. 

How does copper busbar coating work?

  1. Powder Coating uses a dry application rather than a wet paint so that the coating adheres and sticks to the busbar via an electrostatic charge that bonds the coating to the surface on the molecular level.
  2. Copper’s natural high conductivity makes it perfect for the electrostatic charge that bonds the coating to the busbar. We negatively charge the coating by passing it through a spray gun made for this purpose. The negative charge helps bind the coating to the busbar.
  3. The coating is applied in a smooth, uniform application so that the busbars will easily fit the rest of your equipment.
  4. The coating is baked in an oven specifically made for powder coating so that the coating is kept in place.
