How to get started...
Once ampacity, current rating or current-carrying capacity are determined, the next set of questions address physical design factors. Desigers will need to know what hole pattern will be required on both ends, the distance between the holes and the length from end to end. Punching is the most economical hole option, but drilling specific diameters is available and can be readily supplied upon request.
The next critical factor is width, is often a limiting factor and is most often impacted by ampacity. Higher rated braids tend toward wider configurations. Storm stocks flat flex braid in sizes ranging from #6 all the way up to 4/0. When the larger sizes are too wide for the physical limitations of an application, multiple layered flex braids are created to reach the correct related ampacity.
Flat vs. Round Braid
Flat copper braid works well in vertical applications or direct connections where horizontal flexibility is not an issue. Flat braid also has a lower profile and takes up less room in tight quarters.
When horizontal flexibility is specified, round copper braid is used because it bends and flexes equally in any direction.
Reaching the correct ampacity for a given application is also achieved through multiple layers of copper braid. Multiple layers of braid are selected based on total amperage requirements or current density then assembled in a parallel or stacked format according to a customer’s application.
