摘要 |
The invention relates to a composition for coating electric conductors and a method for producing such a composition. The aim of the invention is to create a composition for coating electric conductors which is significantly more resistant to partial discharges than prior art compositions while the produced insulating layer is highly extensible. Said aim is achieved by a composition comprising 1 to 50 percent by weight of microparticles that have a specifically adjusted electronic defect structure in the crystal lattice, resulting in greater polarizability of the valence electrons, and an organic and/or organic-inorganic matrix. The microparticles that have a specifically adjusted electronic defect structure are composed of oxides, sulfides, selenides, tellurides of the elements which are part of the series encompassing silicon, zinc, aluminum, tin, boron, germanium, gallium, lead, the transition metals, lanthanides, and actinides, particularly from the series encompassing silicon, titanium, zinc, yttrium, cerium, vanadium, hafnium, zirconium, nickel, and/or tantalum, in such a way that the basic lattice is provided with vacant lattice positions by doping the basic lattice with adequate low-valent or higher-valent elements, said vacant lattice positions increasing the electronic polarizability of the microparticles by means of defect chemistry (the defect structure). |
