IEC 60660 post insulators of organic material cantilever, tension, torsion strength testing machine
IEC 60660 Insulators - Tests on indoor post insulators of organic material for systems with nominal voltages greater than 1000 V up to
but not including 300 kV
Epoxy cast resin indoor post insulators can be used for all indoor applications.
They are suitable for temperatures from -25 °C up to +90 °C Construction: Epoxy cast resin indoor post insulators are cylindrical solid insulators, with proper creepage and number of ripples. The main dimensions are in accordance with IEC 60273 - 1990. Auxiliary inserts are connected with main insert electrically.
Tests: The following tests, according to IEC 60660 - 1990 are performed:
Routine tests:
» Visual inspection
» Testing of conductive connection of fixing inserts for post insula tors type B (IEC 60660 1999)
» Power-frequency withstand voltage (dry)
» Partial discharge measurement Sample tests:
» Testing of minimum failing load for bending
» Lightning impulse withstand voltage test (on request)
» Testing of minimum failing loads (nominal loads) for bending
