The porcelain long rods failure proof mechanical design eliminates most common possible mechanical failure modes of conventional cap & pin (disc) insulators as well as of composite insulators.
Porcelain long rods are also available with RTV silicone coating to further improve their performance under polluted environmental conditions.
Insulating material: High quality aluminum oxide porcelain, C-130 (IEC 60672)
Coupling: Conforming to IEC, DIN and ÖNORM standards
Cementing: Lead antimony alloy as a standard, portland cement or sulfur possible
Profiles: Porcelain long rod insulators are produced with different shed profiles to optimize performance as per IEC standards that include:
- alternating sheds
- desert profile sheds
- plain sheds
- under rib sheds
