Abstract
The present invention relates to cable comprising a layer comprising a crosslinkable polyethylene composition comprising one or more ethylene copolymer(s) containing monomer units with polar groups and monomer units with hydrolysable silane groups, wherein the monomer units with polar groups are present in an amount of 0.02 to 25 mol. %, and a sulphonic acid, wherein the layer thickness is at least 0.9 mm.
Claims19
A cable comprising a layer comprising a crosslinkable polyethylene composition comprising
- (A1) one or more ethylene copolymer(s) containing monomer units with polar groups and monomer units with hydrolysable silane groups, wherein the monomer units with polar groups are present in an amount of 0.02 to 25 mol. %, based on the total polyethylene composition, and
- (B) a sulphonic acid,
- wherein the layer thickness is at least 0.9 mm.
Use of a crosslinkable polyethylene composition comprising
- (A1) one or more ethylene copolymer(s) containing monomer units with polar groups and monomer units with hydrolysable silane groups, wherein the monomer units with polar groups are present in an amount of 0.02 to 25 mol. %, preferably from 1 to 15 mol. %, more preferably from 2.5 to 15 mol. %, based on the total polyethylene composition, and
- (B) a sulphonic acid
- in a layer with a thickness of at least 0.9 mm of a cable for cross-linking at ambient temperature at increased speed.
