Crown Iso Phase Bus Dew Point Rated Stand offs.
Hi pot videos Crown-sulator vs Porcelain.
Crown Electric uses ONLY dew point rated insulators.
We NEVER need space heaters or pressurization in our IPB – unlike “Others”.
Our insulators will withstand Hi-Pot values more than 3 X operating voltage all while soaking wet.
Porcelain 38 kV, 150 kV BIL GR-3 insulator wet test Hipot - video
Our Crown-sulators beat GR-3 porcelain with 50 % more cantilever strength (4500 ft-lbs. vs 3000 for porcelain) and about 15 % more creep and hi-pot capabilities – again while soaking wet

- Crown-sulators are 1/4 the weight of porcelain
- They do not crack
- They do not hurt your toes if they fall on your safety shoes
- They do not break if dropped during maintenance
- And if they fail, they fail by bending – not snapping like porcelain – so if an earthquake hits your IPB they will not let the conductor break loose of its supports.
