Webfollows [6]: First, polymer insulators are made of organic materials and so subjected to chemical changes on the surface. Second, polymer insulators may suffer from erosion and tracking [3], which may lead ultimately to failure of the insulators. Structure of a polymer insulator [7], is shown in Figure 1. WebCompany Profile: Headquartered in New York and founded in 1893 by Fred Locke, Victor Insulators is the oldest insulator company in the USA.The same year the company was first founded, Locke innovated and patented a wet process method for porcelain that was to be used in power lines – a breakthrough which contributed significantly to the expansion of …
Weblevels, polymer sheds can begin to track and form an electrically conductive path along the surface. The presence of this new conductive path defeats the intended purpose of the insulating material and can lead to a line-to-ground short. These high leakage currents combined with associated dry band arcing can severely damage the polymer surface in
