Water immersion pre-stressing tester for silicon rubber insulator

WATER IMMERSION PRE-STRESSING TESTING MACHINE OF SILICON RUBBER INSULATOR

Insulator polymer tightness tester is used to check tightness of polymer housing of composite insulator, whether the polymeric housing is well attached to FRP will be shown after 96 hours of boiling in salty water. This boiling process is also essential as preparation stage of some electrical test of composite insulator.
