Bead Insulator

An insulator specifically designed to be used as a spacer in, or in conjunction with, such items as coaxial cables, transmission lines, brush shunts, test leads, high voltage lines and the like. Has an axial hole through which the wire passes and the length of which is considerably more than 25 percent of the largest diameter perpendicular to the hole. The external shapes may be variations of cylindrical and spherical shapes.
