Flame Retardant Halogenfree Thermoplastic Telecom Indoor Wiring,
Abstract
Flexible telecommunication cables and jumper wires are packed and formed as multipaired units in switching and main-repeater stations. Due to high values of electronic equipment, telecommunications systems and buildings, the following properties are required in case of fire: all cable and wire components contain nohalogens; no flame propagation, self extinction, no dripping; low smoke density, reduced toxicity, calorific values. Electrical and mechanical properties are to be similar to PVC cables on the whole. The approach discussed here makes use of non-cross-linked, thermoplastic materials which can be processed in existing, conventional extrusion lines economically. The new thermoplastics are suitable for insulation and sheathing, as a substitute for some plastics. Typical and standardized cable designs and their properties are shown. (Author)
