Quick Details
Specifications
Porcelain Line post insulator can be divided into horizontal line posts and vertical line posts according to insulator connectivity way, used for 6kV to 132kV transmission and distribution power lines. Porcelain Line post insulator made of porcelain materials, called line post porcelain insulator which installed with insulator stud. Line post insulator stud can be divided into long insulator stud and short insulator stud. Same dimension of the fittings as porcelain pin insulator, so they can
