    摘要: Polymer concrete electrical insulation system comprising a hardened epoxy resin composition filled with an electrically non-conductive inorganic filler composition, wherein said polymer concrete electrical insulation system optionally may contain further additives, and wherein (a) the epoxy resin composition is based on a cycloaliphatic epoxy resin; (b) the inorganic filler composition is present within the range of about 76 % by weight to about 86 % by weight, calculated to the total weight of the polymer concrete electrical insulation system; (c) the inorganic filler composition comprises a uniform mixture of (i) an inorganic filler with an average grain size within the range of 1 micron (µm) to 100 micron (µm) [component c(i)], and (ii) an inorganic filler with an average grain size within the range of 0.1 mm (100 micron) to 2 mm [component c(ii)]; wherein (d) the inorganic filler with an average grain size within the range of 1 micron (µm) to 100 micron (µm) [component c(i)] is present in an amount within the range of 22 % to 42 %, calculated to the total weight of the polymer concrete electrical insulation system; and (e) the inorganic filler with an average grain size within the range of 0.1 mm to 2 mm [component c(ii)] is present within the range of 41 % to 61 % by weight, calculated to the total weight of the polymer concrete electrical insulation system; and method of producing said electrical insulation system.
