    摘要： A cable comprising an electrical conductor with insulating and protecting layers surrounding the conductor is described. The cable is characterised in that at least one layer selected from said insulating and protecting layers consists of a crosslinked ethylene-alkyl (meth)-acrylate-unsaturated silane terpolymer composition wherein the alkyl (meth)acrylate comonomer comprises more than 5 mole% and the terpolymer composition has a tensile modulus, determined according to ISO 527-2 (1 mm/min) of less than 100 MPa. Preferably, the crosslinked ethylene-alkyl (meth)acrylate polymer is a moisture curable ethylene-alkyl (meth)acrylate-vinyl trialkoxysilane terpolymer, wherein the trialkoxysilan termonomer comprises 0.2-5 % by weight of the polymer composition. The polymer composition may include from 0 up to 50 % by weight of a plasticiser, up to 60 % by weight of a filler, and up to 10 % by weight of an additive.

    摘要： A composition for an insulating layer of a medium to high voltage power cable is disclosed. The composition comprises a cross-linkable polymer with hydrolysable silane groups, and a silanol condensation catalyst of formula (I) ArSO3H or a precursor thereof, Ar being a benzene ring substituted with at least one hydrocarbyl radical such that the total number of carbon atoms of the hydrocarbyl radical (s) is 8-20, or a naphthalene ring substituted with at least one hydrocarbyl radical such that the total number of carbon atoms of the hydrocarbyl radical(s) is 4-18, and the catalyst of formula (I) containing 14-28 carbon atoms in total. A medium to high voltage cable with an insulating layer that has a thickness of more than 2 mm and that comprises the cross-linked product of the above mentioned composition is also disclosed, as is a process of preparing such a cable by cross-linking the cable in the presence of steam at a superatmospheric pressure. Preferably the crosslinking is carried out with saturated steam in a vulcanising tube at about 0.8-1.2 MPa and 170-190°C.
