The main results achieved during development of lead-free insulating compounds for SPEED line HV accessories; materials already tested on model cables in the laboratory, with moulding planned at the Livorno plant; complete industrialisation of a new sheathing material for the Oil & Gas sector, which will reduce costs due to an improved resistance to oils with respect to the original compound; new PVC formulations with improved flame-resistant properties, enabling the Giovinazzo plant to produce smaller and more competitive cables; development of a new LS0H compound for the sheathing of low voltage cables, able to significantly improve the speed of extrusion without affecting cable performance; development of a new class of compounds without halogens but with flame-retardant properties, intended to be lighter with improved performance; in-depth analysis of the combustion mechanism, to better understand the phenomenon and produce compounds whose performance reflects those concepts; development of a new method for measuring the conductivity of gases produced by the combustion of mica glass tapes and compounds for fire-resistant cables consistent with the type of materials used in this application.
