Crown-Sulators and the "Drop Test"

Better mechanical, and electrical properties than glastic or porcelain

Crown Electric uses ONLY dew point rated insulators.
Crown Electric does not need space heaters or pressurization in our IPB.
Crown insulators will withstand Hi-Pot values more than three (3) times their operating
voltage all while soaking wet.

Crown-sulators beat GR-3 porcelain with 50 % more cantilever strength.
(4500 ft.-lbs. vs. 3000 ft.-lbs. for porcelain), approximately 10 % more creep and hi-pot capabilities
– again while wet spray tested.
