The influence of temperature, pollutant, and pH on the local corrosion rate of insulators installed in industrial, marine, and rural installation sites is investigated based on experimental and statistical investigations. The tensile load test confirms that corroded insulator specimens collected from industrial sites aged more than 10 years represent a minimum fracture load, 19,892 lbs. It was further observed that more than 91.

The development of efficient, defect-free, thermal resistive, hard, economical and environment-friendly sealing coating system is required to replace the current polymer-based highly toxic coatings for insulators. This study investigates the suitability of noble cerium (Ce)-based sealing coating film for use as an anti-corrosion coating for insulator pins installed in low-pH and highly corrosive sites.

The development of an efficient, economical, and eco-friendly anti-corrosion coating is essential to replace existing carcinogenic and toxic silicone-based coatings used by insulator industries. This article investigates the anticorrosion performance of a novel cerium-based sealing coating for insulator pins installed in highly corrosive (35 μm per year) industrial regions.
View Article and Find Full Text PDFDue to their great load-bearing capabilities, steel-cement interface structures are commonly employed in construction projects, and power utilities including electric insulators. The service life of the steel-cement interface is always decreasing owing to fracture propagation in the cement helped by steel corrosion. In this paper, a noble crack-resistant solution for steel-cement interfaces utilized in hostile outdoor environments is proposed.
