Original insulation trade vintage catalog for LAPP INSULATOR COMPANY, INC. was located in Leroy, NY. Manufacturers of high-voltage vacuum process insulators, for transmission, distribution, substation and industrial use, hardware and clamps. The Line Post and Station Post were entirely developments of Lapp engineers. Their design came from willingness to abandon traditional concepts and consider anew the requirements of a high voltage insulator. This section briefly summarizes a few of the most usually wanted pieces. Disbound from a large 1943 electrical construction materials book, this unique old eight page technical specifications brochure would display wonderfully matted and framed. A marvelous addition to your retro insulator equipment library. Pages are detached and may contain a small amount of residual glue on edge.
