How igus tests cables in energy chains at sub-zero temperatures

Written by: igus | Published:

Only real long-term tests under realistic conditions provide useful information about the reliability and service life of cables in energy chains.

In this weeks’ video, we head over to Cologne to visit our climatic test chamber. Here chainflex cables move continuously in energy chains where they are subjected temperatures down to -40°C; this is not done just once but millions of times.

Travelling over a distance of 4.35m and at speeds of over 0.7m/s, the cables endure 6,900 cycles every day. A cable only passes the test if it has no jacket fractures.

igus defines three different bending and temperature ranges for the jacket materials it uses. Firstly, for static cables, secondly for flexibly moving cables in accordance with VDE or IEC standards and, thirdly, for cables moving in energy chains.
