In the mid 1960s a few people began collecting these glass and porcelain insulators.
Seves is the result of the integration Sediver PPC Insulators and Isoladores Santana all industrial groups whose history and leadership are recognised throughout the world. Sediver composite insulators Composite insulators were introduced on the market to address the needs of specific line environments and applications. HVDC Catalog International.
Sediver offers innovative high-quality toughened glass insulators designed to perform under all kinds of environmental conditions.
As technology developed insulators were needed for telephone lines electric power lines and other applications. In conjunction with the expansion of rural electrification in the early 20th century there was a major boom in the manufacturing of. Insulators installed on HVDC lines have to sustain very unique and specific stress conditions associated with the unidirectional electrical field and current flow that are generating ionic migration thermal runaway pollution accumulation and corrosion of metal fittings. Eventually desiring a fully European reach they acquired glass plants in Germany 1857 Italy 1889 and Spain.
