Zinc Coating Quality and Insulator Service Life
The hot-dip galvanized coating on insulator metal fittings is the primary defense against atmospheric corrosion. IEC 60383 specifies minimum zinc coating thicknesses (typically 85-100 microns for standard applications, heavier for aggressive environments). Regular thickness testing is a routine QC requirement for insulator manufacturers.
