For safety reasons SCHAKO recommends the use of halogen-free cables. The EasyBus system can, of course, also be equipped and configured with conventional PVC cables. The technical performance is identical for both types of cables. Halogen-free cables offer an number of advantages, which may prove crucial, depending on the application. In case of fire, halogen-free cables do not generate corrosive gases, have have a considerably lower fire load than PVC cables, and generate less smoke. In addition, they are resistant to hydrochloric acid within normal limits. For these reasons halogen-free cable sheaths are increasingly used for data cables.
