ABSTRACT:
A modular lightweight, high voltage guyline insulator for VLF antennas. A glass fiber or "Kevlar" rod tension member that provides high tensile strength is enclosed by a porcelain jacket, which serves as a good high voltage insulator, preventing an arc breakdown along the surface and protecting the tension member from exposure to ultraviolet radiation which could cause the tension member to deteriorate. A rubber sleeve extends between each end of the porcelain jacket and a guyline fastening means, and together with the porcelain jacket forms a cavity or chamber around the tension member which is filled with SF.sub.6 gas, pressurized to 2 to 4 atmospheres (29.4 psia to 58.8 psia). Metal strips and metal toroid corona rings act to diffuse the electric field.
