As a professional insulator manufacturer, the advantage of our porcelain line post insulator lies in achieving high mechanical resistance in addition to their electrical insulation capability.
Porcelain line post insulator formation:
Porcelain line post insulator can be divided into capped line post insulator and capless line post insulator in the light of the hardware installation. Generally speaking, the mechanical strength grade of porcelain line post insulator has 2kN, 4kN, 6kN, 8kN, 10kN, 12.5kN. The capped line post insulator mechanical strength has 2kN and 4kN in the light of its design. Capped line post insulator installed hardware covering at the bottom of porcelain appearance. On the contrary, the metal fitting for capless line post insulator installed in the ceramic with thread.
Porcelain line post insulator design:
Multiple sheds for porcelain line post insulator provide extra leakage distance and uniform leakage path; shaped and spaced for natural cleaning; wind and rain flush off contamination, keep surface resistance high. Short, sturdy sheds of line post insulators design also contribute to the neat, trim appearance of modern overhead construction. The shell of porcelain line post insulator is usually in the same.
