- Dependability - Porcelain is able to withstand long-term
outdoor exposure without significant contamination collection, deterioration,
de-lamination & other performance problems.
- Handling - User is able to lift bushings from flange and
/ or porcelain making for shorter installation periods and less risk to
bushings, equipment & personnel.
- Storage - PRC & POC bushings can be stored without bottom
being in the oil tank and / or high maintenance costs. Non-porcelain insulating
materials are prone to bird and / or rodent damage while kept in inventory.
& Lead Time - Newer technologies can be priced much higher
and have long lead-times.
