Copper Braided Wires By M Pioneer Copper Technologies

Copper braid is made from weaving together strands of copper wire. The flexibility of the braid is determined by the diameter of the copper wire. The smaller the wire the greater the flexibility and the larger the volume occupied by the braid and the more expensive the braid becomes. Our standard sizes are 0.2, 0.1 and 0.05 mm dia although other sizes are available on request.
Flexibility is also determined by the type of weave. Flat braids are flexible in one axis. Round braids are flexible in 2 axis but rope braids are even more flexible than round braids, but also more expensive. An explanation of the construction of a copper braid is on our Products page.
We have a guide for current ratings for different sizes of copper braid at an ambient temperature of 35 deg C and working temperature of 70 deg C. If you have a hotter (or colder) ambient temperature we can calculate the impications for current carrying capacity and potential derating.
