An alternative to the e-spool is the classic Zig-zag application. This is a technology that has proven itself over many years in the stage industry and was used for the first time by igus in 1998 at the Royal Opera London. Zig-zag systems are equally used to supply energy to stage platforms or lighting hoists. Zig-zag systems are also successfully used for the power supply of video cubes (as shown in the product picture). This allows several media to be guided without the need for a slip ring. The modular design and flexibility of the igus e-chains allow a creative solution for vertically suspended applications, which is not only cost-effective, but also particularly space-saving and quiet. It is also possible to add or replace cables later on. Therefore, the system can adapt to changing requirements.
