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 and the "Drop Test"
Better mechanical, and electrical properties than glastic or porcelain
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.
15 kV Crown-Sulators are a bolt for bolt replacement for glastic insulators.
