Electrical cable capable of providing a minimum electrical service during a fire, even when directly exposed to a flame

摘要

The electrical cable, of the type of those comprising at least one insulated conducting core (1) embedded in a jacket (4), is noteworthy in that the jacket (4) is made from polymers of the category of polyolefins which can be crosslinked and which can accommodate a high filler loading in order to create, under the effect of a high temperature, ashes exhibiting good cohesion and a high insulating capacity corresponding to the CR1 category of the Standard NF-C 32310 and to the N.3 test of the Standard NF-C 32070. <IMAGE>
