Guessing power line voltage from the number of disc insulator
Most of california seems to have the same sort of high voltage distribution lines. aka the large metal transmission lines with what seem to be ceramic disc insulators, it seems like there might be a standard for modern ceramic disc insultors $endgroup$ ?C Pasha Reshetikhin Jun 4 13 at 15:19Get Price >>

power - Why do ceramic insulators have a stacked disc .
Ive seen these stacked-disc structures on high voltage power lines everywhere. I could not find any information regarding this particular shape, though. From what Ive noticed, high voltage ceramic insulators only insulate conductors end-to-end (not inside to outside, like traditional plastic insulators).Get Price >>

Pin Insulator. Pin insulators are the earliest developed overhead insulator, but are still commonly Ceramic (Porcelain and Glass) InsulatorsMaterials UsedInsulator StringsPost-Type InsulatorsLong Rod InsulatorsPorcelain is the most frequently used material for insulators. Insulators are made of wet, processed porcelain. The fundamental materials used are a mixture of feldspar (35%), china clay (28%), flint (25%), ball clay (10%), and talc (2%).The alternative method is formation by extrusion bars that are machined into the desired shape. The shells are dried and dipped into a glaze material. After glazing, the shells are fired in a kiln at about 120See more on electrical-engineering-portalPorcelain Disc Suspension Insulators For High Voltage .Application: The porcelain disc suspension insulators are used on the high voltage transmission line and distribution line.
