Post Insulators

Application

Indoor post insulators of cast resin can be used for all indoor plants , also in the tropics. They are suitable for temperatures from -25 °C to +90 °C.

Construction

Indoor post insulators of cast resin are cyclindrical solid insulators. The main dimensions and mechanical requirements are innaccordance with , IEC 60273 -1990.

Test

The following tests to IEC 60660 -1999 are performed :
Type test ,

  • Test with rated power -frequency withstand voltage (dry).
  • Test with rated lightning impulse withstand voltage .
  • Testing of minumum failing loads (nominal loads) for ;
    • Bending , tension ,torsion

Rutin Testler

  • Visual inspection.
  • Dimensional inspection.
  • Testing of conductive connection of threaded fixing bushes.
  • Partial discharge extinction voltage test.
