Abstract
The invention provides a cable, preferably a power cable, comprising one or more conductors surrounded by at least one layer, preferably an insulation layer, wherein said layer comprises a polymer composition comprising: (i) at least 75 wt % of an ethylene based plastomer; and (ii) 0.2 to 10 wt % of an amine filler, oxide filler or mixture thereof; and wherein said polymer composition has a dielectric loss expressed as tan δ (50 Hz) of 200×10−4 or less, when measured at 500 V/mm and 90° C. as described in the description part under “Determination methods”.
Claims20
A cable comprising one or more conductors surrounded by at least one layer, wherein said layer comprises a polymer composition comprising:
- 90 to 99.8 wt % of an ethylene based plastomer;
- and
- 0.2 to 10 wt % of an amine filler, an oxide filler, or mixtures thereof;
- and wherein said polymer composition has a dielectric loss expressed as tan δ (50 Hz) of 200×10−4 or less, when measured at 500 V/mm and 90° C. as described in the description part under “Determination methods”.
A cable comprising one or more conductors surrounded by at least one layer wherein said layer comprises a polymer composition comprising:
- (i) 10 to 40 wt % of an ethylene based plastomer;
- and
- (ii) 60 to 90 wt % of a polyolefin (a) selected from the group consisting of an LDPE, polypropylene homopolymer, random heterophasic polypropylene copolymer and mixtures thereof;
- and wherein said polymer composition has a dielectric loss expressed as tan δ (50 Hz) of 200×10−4 or less, when measured at 500 V/mm and 90° C. as described in the description part under “Determination methods”.
