The present invention relates to an insulation material for use in MV and HV power systems comprising - at least one Ci_i0-olefin polymer in an amount of up to 99 wt% of the total weight of the insulation material, - a crosslinker in an amount between 0.01 and 0.6 wt%, and - a crosslinkable organic ion scavenger of formula (I), wherein: A is an aromatic cycle or aromatic heterocycle comprising one or more rings, whereby the heterocycle comprises one or more atoms selected from O, N and S, n is 1 to 10, L is a spacer selected from the group comprising -CH2-, C2H4-, - (CH2)0-2-O-(CH2)0-2, -(CH2)0-2-S-(CH2)0-2, -(CH2)0-2-N-(CH2)0-2, -(CH2)0-2- C(O)-(CH2)0-2, -(CH2)0-2-O-C(O)-(CH2)0-2 and -(CH2)0-2-C(O)-O-(CH2)0-2, and t is 0 to 10, in an amount between 1 and 30 wt%, and whereby the weight ratio between the crosslinker : the crosslinkable organic ion scavenger is between 1 : 7 and 1 : 300. |
