15 years of washing-free insulation

Customer challenge

One of our customers had to address very heavy industrial and coastal pollution. At first composite was considered but reliability of this technology reached its limits after only few years in service.

What we delivered

Italy turned to coated glass insulators with more than 1.5 million coated insulators installed, with no washing and no pollution-related flashover for more than 15 years. Sediver operates a yearly monitoring of samples selected from key transmission lines (AC and DC) in collaboration with the local Utility.
