Audits

Insulator type testing

Insulators are designed and tested to the requirements of DIN VDE 0441 Part 3 and IEC 60660 and IEC 60060-1.

The audit includes:

  • Withstanding voltage (IEC 60060-1)
  • Rated lightning impulse withstand voltage (IEC 60071-1)
  • Alternating voltage (AC)
  • Withstanding alternating voltage, dry
  • Flashover alternating voltage, dry
  • Water absorption test
  • Aging test
