Dye Penetration is a technique utilized to identify where voids exist within insulating materials, whether it be stranded polymer insulator rods or composite cores utilized in transmission line conductors.


  • Zyglo
  • Fuchsine

We use Zyglo and Fuchsine dye penetrants for testing that help locate and identify surface defects and voids in materials in order to screen out potential failure-producing defects.
