Process for the reduction of breakdown risks of the insulant of high voltage cables and lines during their aging

摘要

Process for the reduction of breakdown risks with respect to the solid dielectric insulant of transmission cables and lines operating under high voltages. The insulant normally separates the conductors of a multi- conductor line or the central conductor and the outer metal envelope of a coaxial line. Small amounts of metal particles with dimensions below 1 micron are added to the dielectric insulant mass.
