ABSTRACT:
An improved electrical insulator for high voltage transmission lines is formed from certain polymer-based concrete compositions. An apparatus provides for the molding of the polymer-based mixture to form a highly degassed product. The method and apparatus include the ability to combine the constituents of the mixture in a mixer. A vacuum is applied to the mixture to degas the mixture. A mold is filled with the degassed mixture without introducing air thereinto in the absence of a vacuum. The resulting insulator has highly reduced air entrainment.
