Abstract

La presente invención se refiere a mejoras en aislador eléctrico, que comprende un miembro alargado generalmente cilíndrico compuesto de material dieléctrico y teniendo substancial fuerza mecánica, conexiones de extremo aseguradas al miembro alargado, y una serie de cubiertas de intemperización que encierran al miembro alargado y cubriendo toda la superficie del miembro alargado entre las conexiones las cubiertas de intemperización, estando compuestas de un material aislante elastomérico, la mejora está caracterizada porque cada cubierta de intemperización tiene una abertura completa de una sección transversal en el estado sin esfuerzo que es más pequeña que la sección transversal del miembro alargado, por lo que, las cubiertas de intemperización están bajo tensión de lazo en la superficie del miembro alargado, y las cubiertas de inteperización están comprimidas longitudinalmente entre las conexiones mencionadas, por lo cual las superficies interiores de las aberturas de las cubiertas de intemperización ejercen presión sobre el miembro alargado y las cubiertas de intemperización ejercen presión una sobre la otra.The present invention relates to improvements in electrical insulator, which comprises a generally cylindrical elongated member composed of dielectric material and having substantial mechanical strength, end connections secured to the elongated member, and a series of weathering covers that enclose the elongated member and covering the entire surface of the elongated member between the connections the weathering covers, being composed of an elastomeric insulating material, the improvement is characterized in that each weathering cover has a full opening of a cross section in the effortless state which is smaller than the cross section of the elongated member, whereby the weathering covers are under loop stress on the surface of the elongated member, and the weathering covers are longitudinally compressed between the aforementioned connections, whereby the interior surfaces of the openings of the covers The weathering covers put pressure on the elongated member and the weathering covers put pressure on each other.
