An electrical cable () includes an elongate electrical conductor () surrounded by at least one crosslinked layer () obtained from a polymer composition including a polymer material and a protection system. The protection system includes diphenylamine or a diphenylamine derivative and a sulfur compound selected among an organic thiol, a thiolate, and one of the mixtures thereof.

Electrical cable including a crosslinked layer

The invention concerns organopolysiloxane compositions obtainable by the following successive steps: step 1: reacting (i) at least a linear diorganopolysiloxane reagent A comprising a hydroxyl group at each chain end; (2i) and at least a hydroxyl organopolysiloxane resin B having a weight content of hydroxyl group ranging from 0.1 to 10%; (3i) with at least a polyalkoxysilane C; step 2: introducing in the medium of step 1 (6i) a mineral filler G based on amorphous silica and (7i) an efficient amount of a catalyst H consisting of at least one titanium organic derivative; step 3: the resulting mixture is subjected to devolatilization carried out at a pressure less than atmospheric pressure.

The invention concerns a coating composition capable of being cold vulcanised (EVF), characterised in that it comprises, in a mixture: (1) at least one polyorganosiloxane having, per molecule, at least two C -C alkenyl groups bound to silicon; (2) at least one polyorganosiloxane having, per molecule, at least two hydrogen atoms bound to silicon; (3) a catalytically effective amount of at least one catalyst, consisting of at least one metal belonging to the platinum group; (4) an adherence promoter; (5) optionally a reinforcing system which can be at least a polyorganosiloxane resin and/or a reinforcing filler; (6) optionally at least one cross-linkage inhibitor; (7) and mineral or organic hollow microspheres.

The polyorganosiloxane composition resulting in a silicone elastomer of high thermal conductivity, which can reach and even exceed 1.2 W/m.K, the elastomer retaining an elongation at break of greater than 30%, comprises at least one functional polyorganosiloxane which crosslinks by a polyaddition or polycondensation reaction or by the radical route, optionally a polyorganohydrosiloxane, a catalyst, optionally a reinforcing filler and a filler intended to increase the thermal conductivity which is present in the composition in the proportion of 35 to 70% by volume with respect to the total composition, this filler comprising at least two groups of particles of very different mean diameters, a first group having a mean particle diameter of between 10 and 40 mm, present in a predominant amount in the filler, and a second group having a mean particle diameter of less than 5 mm.
