Abstract (en)
[origin: WO9214253A1] In a method for reducing the risks of breakdown of the solid dielectric insulator of transmission lines and cables operating at high voltage where said insulator normally separates the conductors of a multiwire line or the central conductor and external metal sheath of a coaxial line, small quantities of metal particles smaller than a micron are added into the dielectric insulating material.
