A flame-retardant electric cable (10) is disclosed, the cable having a core comprising an electric conductor (11) and an electrically insulating layer (12) made from a flame-retardant polyolefin-based composition comprising: a) a cross-linked polyolefin as base polymer; b) silica; and c) carbon nanotubes wherein the amount of silica is from 5wt% to 10wt% of the polyolefin- based composition, and the amount of carbon nanotubes is from 0.5wt% to 2wt% of the polyolefin-based composition. Such a cable has improved flame retardant performances, especially regarding a lower occurrence of droplets during burning, which render it capable of being certified in higher classes of the current international standards, for example of the standard EN 50399:2011/A1 (2016).

Abstract
A flame-retardant electric cable (10) is disclosed, the cable having a core comprising an electric conductor (11) and an electrically insulating layer (12) made from a flame-retardant polyolefin-based composition comprising: a) a cross-linked polyolefin as base polymer; b) silica; and c) carbon nanotubes wherein the amount of silica is from 5wt% to 10wt% of the polyolefin- based composition, and the amount of carbon nanotubes is from 0.5wt% to 2wt% of the polyolefin-based composition. Such a cable has improved flame retardant performances, especially regarding a lower occurrence of droplets during burning, which render it capable of being certified in higher classes of the current international standards, for example of the standard EN 50399:2011/A1 (2016).| File | Dimensione | Formato | |
