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.

Crown-sulators are 1/4 the weight of porcelain
If dropped during inspection & maintenance, Crown-sulators do not crack or shatter.
A dropped Crown-sulator will not smash your safety shoe covered toes.
Under excessive duress - if they should fail, they fail by bending
– not snapping like porcelain.
Crown-sulators will not allow properly designed IPB conductor to
break loose of its supports.

- 150 kV BIL GR-3 porcelain insulator under wet-test hipot

- 150 kV BIL Crown-sulator under wet-test hipot

A 15kV / 95 kV BIL version – for

7EA Gas turbines and switchgear

15 kV Crown-Sulators are a bolt for bolt replacement for glastic insulators.
