Likewise, Sediver launched the concept of an <strong>undercoated insulator around 2010<\/strong> with extensive test results in various pollution conditions. <strong>This approach<\/strong> to substitute polymer insulators with hydrophobic surface over glass (but also porcelain) <strong>has substantially impacted the selection of insulators in polluted environments<\/strong> in which so far polymer insulators were used for their performance in contaminated environment.<\/p>\n\n\n\n<p>Today many companies offer silicone coated insulators either glass or porcelain and coating is either being applied in factories or on site. The latter case can be divided in two different approaches either <strong>directly on the tower or in the direct vicinity of the line or in temporary \u201csheds\u201d or \u201cspecialized containers\u201d trying to duplicate the quality and consistency of factory-made products<\/strong>.<\/p>\n\n\n\n<p>Some performances are still being debated among which adherence which will be discussed in this paper.<\/p>\n\n\n\n<p>More interest also for <strong>HVDC applications.<\/strong> In fact, except for China which has already used extensively coated insulators next to polymers in DC there are very few DC lines in severely polluted environments around the world. This will be discussed as well in this contribution.<\/p>\n\n\n\n<p>Finally, a relatively unique field experience will be discussed bringing some light to the<strong> far limits of performance of coated insulators in extreme conditions, far beyond the pollution classification from IEC TS60815<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Read the paper<\/h2>\n\n\n\n<p>You can read the paper through our download center or by <a href=\"https:\/\/www.sediver.com\/wp-content\/uploads\/SEDIVER_Coating_INMR_BERLIN-1.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">clicking on this link<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Listen to the presentation <\/h2>\n\n\n\n<p>Our scientific director have presented this paper during the last INMR congress.
