Copper braids

The copper braid is used as a super flexible conductor for all electric connection requirements, including power, earthing and equipotential connections.

Copper braids

It results from the use of a number of standard wires with diameter between 0.10 and 0.30 mm, twined together to form a cord.

More cords twined together can produce a small cross-sectioned braid or further secondary cords which, twined again, make it possible to get the desired cross-section.


It is used for power and mass connections, and, when suitably insulated, as an alternative to the cables. In that case, compared to insulated cables, with the same cross-section, it allows more current density and, most of all, extraordinary flexibility.


It is used as a protection sleeve for electric cables inserted inside of the braid, thus producing screens and protections against interferences and/ or disturbances.


It is used for power, earthing and equipotential connections. In power applications, it makes flexible connections which easily compensate offsets between elements to be interconnected, and also provides excellent buffering of vibrations induced by, i.e., connection to a transformer. With the same cross-section, it can take a higher current density than cables or copper bars.
