PURPOSE: A crosslinkable silicon composition exhibiting one or more of improved tracking resistance, high arc resistance, and decreased flammability is provided. Organopolysiloxanes capable of producing an elastomer by cross-linking the crosslinkable composition and a cross-linked product prepared from the composition are effectively used for manufacture of material for electric equipment, middle and high voltage insulator, cable pot head, anode cam, compression molding and extrudate. CONSTITUTION: About 50 to 90% by weight of organopolysiloxane having a viscosity of from 50 to 100x10¬6 mm¬2/s at 25 C. is mixed with 10 to 50% by weight of a metal oxide from the group consisting of titanium oxide, zirconium dioxide, zinc oxide, cerium(III) and cerium(IV) oxide, 0.3 to 5% by weight of an organosilicon compound containing basic nitrogen bound to silicon via carbon, 0.05 to 0.5% by weight of platinum calculated as the element, in the form of a bis(alkynyl)platinum complex which additionally includes donor ligands, and 0 to 5% by weight of another component, the sum of the percentages of the component being 100% by weight.
