As explained by Cal Manufacturing in their article “Copper Laminated Shunt Action,” copper laminated shunts play a vital role in various industrial applications. These shunts are constructed by stacking foils of electrolytic copper, which are then wound into specific shapes to meet their intended purposes. Their applications span a wide range, from resistance welding and switch gear to transformers, electric locomotives, and more.
One of the remarkable advantages of choosing copper laminated shunts is their exceptional flexibility. They are designed to fit seamlessly into tight spaces, making them highly versatile in different settings. These shunts consist of stacked strips with riveted or welded/soldered contact areas, ensuring a constant cross-section along their entire length. This uniformity allows busbars and laminated connectors with the same cross-section to carry the same current. In many cases, parts of laminated connectors also serve as flexible expansion connectors, connecting bus bars in switch gear, transformers, or generators, and dampening vibrations in switch gear. Additionally, some components of these shunts play a pivotal role in welding equipment.
The assembly of copper shunts is critical to optimize their performance. Various assembly methods, such as press welding, riveting, dip soldering, clips, and plates, are employed to ensure they function effectively within the equipment they are placed on.
Copper laminated shunts find applications across diverse industries, replacing traditional bus bars in some cases. They are integral to industries like resistance welding engineering, switch gear, electric locomotives, power plants, solar energy, and many more. These shunts are crucial components in various industrial processes, including caustic soda and chlorine plants, transformers, furnaces, and a wide array of other applications.
