  • welding flexible copper stranded wire


The stranded wire is designed to provide dynamic characteristics and fundamental flexibility for proper operation in various environments.

Installers find stranded copper wire easier to handle in tight areas and inside buildings due to its increased flexibility and the ability to be manipulated quickly by hand. This makes it an ideal choice for connecting electronic circuit components in confined spaces, where its bending and twisting capabilities can be effectively utilized.

A stranded conductor is very flexible; it can be coiled easily, packed and be transported over a long distances.

The flexibility of any conductor will increase with the number of strands.

Stranded conductors are formed by winding the strands together in several layers.

The several strands are laid one on top of the other in a helical format, a process commonly known as stranding.

For the stranding to hold, successive layers are laid opposite the direction of the preceding layer. The first strand is twisted clockwise, while the following layer is twisted counter clockwise, a process that is repeated as the layers are added.

The formula gives the total number of strands of any given conductor. N = 3 x2 - 3 x + 1, Where N refers to the total number of strands in the conductor

The diameter of the conductor is calculated by using the following formula D = (2 x – 1)d, where D refers to the diameter of the given conductor and d refers to the diameter of each strand.
