Porcelain Longrod Insulators Designed for Demanding Environments

May 13, 2024
PPC Insulators exhibited at the 2024 IEEE PES T&D show in Anaheim, California.

PPC porcelain longrod insulators are used in transmission and distribution lines. The strength of the porcelain and modern design make them a safe and reliable solution for demanding environments, according to the company.

Compared to other types of insulators, they are suitable for a safe and stable power supply without power failure with low operating costs. Under polluted conditions, insulators can be subjected to extreme electrical field stress causing tracking and erosion.

Porcelain insulators will only show minor surface marks but maintain 100% mechanical strength. Porcelain Long Rod insulators are not affected by UV, wind, rain, ice and temperature changes. They will provide reliable service for the life of the conductors and towers.

Porcelain longrod insulators have high dielectric strength. Aluminum oxide ensures the low porosity of porcelain. This ensures the porcelain is impervious to moisture and will not lose its mechanical properties due to freezing.

All components of porcelain insulators are fully recyclable in the manufacturing process and throughout their life cycle. Compared to other insulation materials, they leave a significantly lower carbon footprint. Once properly installed, the porcelain longrod insulators retain reliability for decades.
