Abstract

Wire and cable are demanded to have not only high reliability in electrical and mechanical properties, but also low disaster characteristics from the viewpoint of fire safety. For this purpose, Fujikura have supplied low smoke, halogen free and flame retardant cables “Clean Cable” since 1983. From the viewpoint of environmental protection, we have developed a new type of halogen free recyclable cable with low toxic gas emission “Eco-Cable” since 1998. Our new recyclable cable material is low density (d=1.1), halogen free and flame-retardant material. We have examined to separate the cable jacket (new material and PVC) and insulation (XLPE) using density difference. We employed the liquid cyclone method which developed at Hitachi, Ltd.. As a result, XLPE (d=0.9), new material (d=1.1) and PVC (d=1.4) are separated by purity 99.6%, 99.9%, and 99.3% respectively.
