Abstract (en)

[origin: WO0008655A1] An electric DC-cable with an insulation system comprising an extruded polyethylene composition and a method for manufacturing such a cable. The insulating system comprises an extruded cross-linked polyethylene based insulation disposed around the conductor. The extruded insulation system in addition to the polyethylene based compound includes an additive, which is a glycerol fatty acid ester of the general formula (I): R<1>O(C3H5(OR<2>)O)nR<3> where n>/=1, R<1>, R<2>, and R<3>, which are the same or different, designate hydrogen or the residue of a carboxylic acid with 8-24 carbon atoms, with the proviso that there are at least two free OH groups and at least one residue of a carboxylic acid with 8-24 carbon atoms in the molecule. In the method for producing the DC-cable the compounded polyethylene based composition is extruded and cross-linked at a temperature and for a period of time sufficient enough to cross-link the insulation.
