The general advantages of igus® products are low weight, corrosion resistance, protection against weather and dirt, and freedom from maintenance and lubricants. The e-chain® used was determined according to the available installation space. The length, width, height and bend radius of the e-chain® played a major role in this, and students Fey and Schrott opted for a closed system that protects cables from dirt and damage. The zipper system was chosen to make it easier to lay the cables. This enables the feed-through of the cables after the e-chain® has been installed.
