This was designed to improve corrosion resistance so that it can be used in special environments where SiC deterioration is quicker, while all the electrical specifications and shapes are the same as types E, F, and U. It can be used in extraordinarily toxic atmospheres with existence of nitrogen, hydrogen, alkali, lead, halogen and others. Various coatings can be applied to improve oxidation resistance and corrosion resistance depending on applications.
