The flexibility of our fabric tapes is determined by their design. The higher the number and the smaller the diameter of the individual wires, the more flexible the finished product will be.

Thus, it is possible for all flat copper conductors to be precisely geared towards the desired application.

Table of current loads

Below you can select your appropriate cross-section as a function of the current load (determined at a room temperature of 35 °C and the maximum temperature of the conductor, viz. 70 °C).

Due to other factors usually playing a role as well, the values indicated below are to be seen as a non-binding recommendation.
