How is the thickness of a copper braided wire measured?

The thickness of a copper braided wire is typically measured using the following methods:  

1. Measuring the Overall Diameter  

- The overall thickness (diameter) of the braided wire is measured using a caliper or micrometer.  

- This includes all the individual copper strands woven together.  

2. Determining the Cross-Sectional Area  

- The cross-sectional area of the braided wire is often specified in square millimeters (mm²) or American Wire Gauge (AWG).  

- To calculate the cross-sectional area, manufacturers sum up the areas of all individual strands.  

3. Measuring Individual Strand Thickness  

- Each copper strand's diameter is measured separately using a micrometer.  

- The number of strands and their thickness determine the overall wire size.  

- Example: A 10 mm² copper braid might consist of 100 strands of 0.1 mm diameter each.  

4. Using Standard Wire Gauge (AWG or SWG)  

- Copper braided wires are often classified using AWG (American Wire Gauge) or SWG (Standard Wire Gauge).  

- Manufacturers provide specifications like "10 AWG braided wire", which refers to a standard thickness.  

5. Checking Manufacturer Specifications  

- Most copper braided wires come with predefined thickness values in technical datasheets, specifying overall diameter, strand count, and individual strand size.
