How to Connect on Copper Busbars?

If you have an electrical system with a number of different outlets, bus bars are a great way to connect them. They are flexible and can be re-located easily to meet changing demands. They also provide power monitoring which helps you to make purposeful energy efficient decisions.

The first step in connecting a bus bar is to choose the correct hardware for the job. There are many options for fastening hardware, including screws, bolts, pins and self-clinching fasteners. The right choice will depend on your application and the amount of torque you need to apply to the fastener.

Bolts are the most common type of fastener used for bus bars, and they are easy to use. However, there are some drawbacks to using this type of hardware. The most common problem is that copper alloys can be corroded by fasteners, so we recommend using stainless fasteners with self-clinching screws instead.

Another disadvantage of a conventional fastener is that it can become contaminated with dirt and moisture. This can lead to corrosion on the metal surface, which will reduce its conductivity. This is why we typically use stainless fasteners for custom copper bus bars.

A powder coating is a great option for protecting your bus bars from corrosion. It can also help to improve their electrical conductivity, but it is important to mask off the contact areas where you want the powder coat to be applied.

In some cases, it is possible to powder coat the entire bus bar, but this will reduce its electrical conductivity. This can be avoided by specifying the contact areas where you would like to mask off.

Tin plating is another option for improving the conductivity of your busbars. This process is simple and involves immersing the copper in a bath of pure tin. This gives the bus bar more corrosion resistance, while also increasing its solderability. The downside to tin plating is that it must be completed by a third-party supplier, so be sure to factor that in when estimating your cost.

Powder coating also protects your bus bar from rusting, which can happen when copper and aluminum come into contact with each other in an electric circuit. The two materials can corrode differently and cause problems for your bus bar system, so it is important to choose a copper powder coating that will minimize this issue.

We can also help you select the best type of powder coating for your project. Check out our selection of high-quality powder coats, which include anti-corrosion, UV-resistant, and abrasion-resistant options.

Aluminum is a common metal for busbars because it is lightweight and costs less than copper. It is often used in aircraft, as well as in overhead utility transmission lines. It is also an excellent option for outdoor electrical switchyards, which need to withstand a wide range of environmental conditions and extreme temperatures.

Both copper and aluminum have their own strengths and weaknesses, and it is up to you to determine which one will suit your application best. Regardless of which material you choose for your busbar, it must be manufactured to industry and environmental standards and installed correctly.
