Giesche porcelain power isolator

A power isolator, whose purpose is to isolate power transmission wires, is one of the most widely used objects of this type found in power engineering. Power isolators were initially made of glass or, as is the case here, of electrical porcelain – at the time both materials were considered cheap and durable. The item presented here was produced by the factory of the descendants of the Wroclaw merchant Jerzy Giza (Georg von Giesche), which operated without interruption from the end of the 17th century until the mid-20th century in Upper Silesia. The enterprise operated the mining of coal and metal ores, a steelworks, and a fertilizer factory. In 1925 it opened the Giesche Fabryka Porcelany SA porcelain factory (previously Czuday), which produced electrical engineering products and porcelain tableware.
