Porcelain Longrod insulator is one of special porcelain insulators made of high strength alumina porcelain, can withstand continuous or changing mechanical electrical and thermal influences. Porcelain Longrod insulator has puncture- proof and is one of solid core insulator used in contamination areas. Superior dielectric and mechanical properties of Porcelain longrod insulators improve the reliability and stability of high voltage and extra high voltage transmission lines.



According to insulator standards, the main insulator technical data, insulator drawings and insulator code number for porcelain longrod insulator is as follow.
